I'm working on .NET Core where I'm trying to masking some sensitive data like emailid, password, etc.. I want all my json response data keys or properties name should be in lowercase for that I'm using one of the feature of Newtonsoft e.g ContractResolver which helps us to customize property name.
But it seems, it only works with generic class type e.g
class customer
{
public string firstName { get; set; }
}
but it not working when we have json string e.g
{\n \n \"firstName\": \"Testbusiness\",\n \"lastName\": \"business\",\n}
now i'm looking for how to convert json response to specific object type dynamically so that i can pass that object to contractResolver checkout below code.
public class LowerCaseResolver : DefaultContractResolver
{
protected override string ResolvePropertyName(string propertyName)
{
return propertyName.ToLower();
}
}
using Newtonsoft.Json;
using SerializationContractResolverExample.ContractResolver;
using System;
namespace SerializationContractResolverExample
{
class Program
{
static void Main(string[] args)
{
CustomerInfo customerInfo = new CustomerInfo()
{
FirstName = "Sukhpinder",
LastName = "Singh",
MobileNumbers = new System.Collections.Generic.List<string>() {
"33443434343"
}
};
var sestting = new JsonSerializerSettings
{
ContractResolver = new LowerCaseResolver()
};
// need to convert below response to dynamic generic type
string tem1 = "{\n \"lmsUserId\": 10268,\n \"landlordProfileId\": \"2ea81674-6ca6-478c-a9c6-fefbe9572f28\",\n \"firstName\": \"Testbusiness\",\n \"lastName\": \"business\",\n \"email\": \"yesteluydi#vusra.com\",\n \"createdBy\": 1551,\n \"createdDate\": \"2022-05-05T17:05:10.37\",\n \"user\": null,\n \"linkedLLCs\": null,\n \"ssn\": null,\n \"accountTypeId\": 2,\n \"completeLater\": false\n}";
var responseLowerCase = JsonConvert.SerializeObject(tem1, Formatting.Indented, sestting); //Not working
var responseLowerCase = JsonConvert.SerializeObject(customerInfo, Formatting.Indented, sestting); //Working Fine
Console.WriteLine(responseLowerCase);
Console.ReadLine();
}
}
}
You can try to use JsonConvert.DeserializeObject to convert tem1 to Object .
string tem1 = "{\n \"lmsUserId\": 10268,\n \"landlordProfileId\": \"2ea81674-6ca6-478c-a9c6-fefbe9572f28\",\n \"firstName\": \"Testbusiness\",\n \"lastName\": \"business\",\n \"email\": \"yesteluydi#vusra.com\",\n \"createdBy\": 1551,\n \"createdDate\": \"2022-05-05T17:05:10.37\",\n \"user\": null,\n \"linkedLLCs\": null,\n \"ssn\": null,\n \"accountTypeId\": 2,\n \"completeLater\": false\n}";
var s = JsonConvert.DeserializeObject<Object>(tem1);
result:
using .NET C#, I am trying to create a new JObject from a JArray. I have a FetchData JObject that I want to return a JObject of data for data driven testing. Here is what I have so far:
public static JObject FetchData(string testMethodName)
{
using (StreamReader r = new StreamReader("PathToJsonfile"))
{
string jsonstring = r.ReadToEnd();
JObject obj = JObject.Parse(jsonstring);
JArray jsonArray = JArray.Parse(obj[testMethodName].ToString());
JObject jObject = new JObject(new JProperty("test",jsonArray));
return jObject;
}
}
I want to return a JObject of test data that pertains to the testMethod which is being run. when I run this code, jObject returns:
"test": [
{
"loginId": "testuser1",
"userCase": "verify for user"
},
{
"loginId": "testuser2",
"userCase": "verify for user"
}
]
My issue is that I only want to return the following arrays within the JObject:
{"loginId":"testuser1","userCase":"verify for user"}
I have researched for a while and cannot find a solution without adding a key to the new JObject, in this case, key being "test".
Is this even possible in C#?
I have also tried adding the JArray directly to the JObject:
JObject jObject = new JObject(new JObject(jsonArray));
but get error : System.ArgumentException: 'Can not add Newtonsoft.Json.Linq.JArray to Newtonsoft.json.Linq.JObject
I have also tried adding the arrays to the JObject like this:
for (int i = 0; i < jsonArray.Count; i++)
{
jObject[i] = jsonArray[i];
}
but get error : System.ArgumentException : Set JObject values with invalid key value: 0. Object property name expected.
fwiw this is how I am doing this is Java and it works like a charm, but I cannot figure it out in C#. Java Code:
JSONObject[] jsonObject = new JSONObject[jsonArray.length()];
for (int i = 0; i < jsonArray.length(); i++) {
jsonObject[i] = jsonArray.getJSONObject(i);
}
To get first element of array you can do next:
var json = #"{
""test"": [
{
""loginId"": ""testuser1"",
""userCase"": ""verify for user""
},
{
""loginId"": ""testuser2"",
""userCase"": ""verify for user""
}]
}";
var testMethodName = "test";
var jObject = JObject.Parse(json);
var first = (JObject)jObject[testMethodName][0]; // note that this can throw for multiple reasons
Analog of your java code would be:
// parse jObject as earlier
var jArr = (JArray)jObject[testMethodName];
var jsonObjectArr = new JObject[jArr.Count];
for (int i = 0; i < jArr.Count; i++)
{
jsonObjectArr[i] = (JObject)jArr[i];
}
Or you can use LINQ to JSON:
// parse jObject as earlier
var jsonObjectArr = jObject[testMethodName]
.Children<JObject>()
.ToArray();
Why don't you return only the first object of your array like this:
public static JToken FetchOneDatum(string testMethodName)
{
string jsonString = GetFileContent("sampleTest.txt");
JObject obj = JObject.Parse(jsonString);
JArray jsonArray = JArray.Parse(obj[testMethodName].ToString());
return jsonArray[0];
}
You can find the whole visual Studio solution here:
solution on GitHub
C# approach ;)
public class Test
{
public string loginId { get; set; }
public string userCase { get; set; }
}
public class Scenario
{
public Test[] tests { get; set; }
}
// Usage
public static Test FetchData(string testMethodName)
{
using (var reader = new StreamReader("PathToJsonfile"))
{
var json = reader.ReadToEnd();
var scenario = JsonConvert.DeserializeObject<Scenario>(json);
return scenario.tests.First();
}
}
I am receiving response from httpWebRequest as a string, which is format of JSON. What I would like, is to change this string to json and then, there are two opitons
1) change json to the 2D array
2) change json to dictionary
The point is I want to have easy access to the variables.
This is a string I am receiving:
"[{\"Year\":2000,\"Name\":\"Ala\",\"Val\":0.5},{\"Year\":2001,\"Name\":\"Ola\",\"Val\":0.6}... {\"Year\":2004,\"Name\":\"Ela\",\"Val\":0.8}]"
So as you can see I could have table with n rows and 3 columns (Year, Name, Val).
This is the code which I use to receive the response
var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://127.0.0.1:5000/");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
//send request data in json format
streamWriter.Write(jsonData);
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
//take data as string
var result = streamReader.ReadToEnd();
}
return null;
}
Instead of null I will return this array/dictionary.
Which way is better? Someone know how to make it? I feel lost in c#.
Thank you for help in advance!
First, to make work with JSON easier you can install Newtonsoft.Json package
Install-Package Newtonsoft.Json -Version 11.0.2
Then add using Newtonsoft.Json;
Look at this example
public class Item
{
public int Year { get; set; }
public string Name { get; set; }
public double Val { get; set; }
}
public class Program
{
public static void Main()
{
string json = "[{\"Year\":2000,\"Name\":\"Ala\",\"Val\":0.5},{\"Year\":2001,\"Name\":\"Ola\",\"Val\":0.6},{\"Year\":2004,\"Name\":\"Ela\",\"Val\":0.8}]";
List<Item> items = JsonConvert.DeserializeObject<List<Item>>(json);
foreach(var item in items)
{
Console.WriteLine("Year: {0}; Name: {1}; Val: {2}", item.Year, item.Name, item.Val);
}
}
}
Here I create a new class Item witch will be represents one object from array from your JSON. Then using Newtonsoft.Json deserialize json string to list of items.
Trying to convert a JSON string into an object in C#. Using a really simple test case:
JavaScriptSerializer json_serializer = new JavaScriptSerializer();
object routes_list = json_serializer.DeserializeObject("{ \"test\":\"some data\" }");
The problem is that routes_list never gets set; it's an undefined object. Any ideas?
Or, you can use the Newtownsoft.Json library as follows:
using Newtonsoft.Json;
...
var result = JsonConvert.DeserializeObject<T>(json);
Where T is your object type that matches your JSON string.
It looks like you're trying to deserialize to a raw object. You could create a Class that represents the object that you're converting to. This would be most useful in cases where you're dealing with larger objects or JSON Strings.
For instance:
class Test {
String test;
String getTest() { return test; }
void setTest(String test) { this.test = test; }
}
Then your deserialization code would be:
JavaScriptSerializer json_serializer = new JavaScriptSerializer();
Test routes_list =
(Test)json_serializer.DeserializeObject("{ \"test\":\"some data\" }");
More information can be found in this tutorial:
http://www.codeproject.com/Tips/79435/Deserialize-JSON-with-Csharp.aspx
You probably don't want to just declare routes_list as an object type. It doesn't have a .test property, so you really aren't going to get a nice object back. This is one of those places where you would be better off defining a class or a struct, or make use of the dynamic keyword.
If you really want this code to work as you have it, you'll need to know that the object returned by DeserializeObject is a generic dictionary of string,object. Here's the code to do it that way:
var json_serializer = new JavaScriptSerializer();
var routes_list = (IDictionary<string, object>)json_serializer.DeserializeObject("{ \"test\":\"some data\" }");
Console.WriteLine(routes_list["test"]);
If you want to use the dynamic keyword, you can read how here.
If you declare a class or struct, you can call Deserialize instead of DeserializeObject like so:
class MyProgram {
struct MyObj {
public string test { get; set; }
}
static void Main(string[] args) {
var json_serializer = new JavaScriptSerializer();
MyObj routes_list = json_serializer.Deserialize<MyObj>("{ \"test\":\"some data\" }");
Console.WriteLine(routes_list.test);
Console.WriteLine("Done...");
Console.ReadKey(true);
}
}
Using dynamic object with JavaScriptSerializer.
JavaScriptSerializer serializer = new JavaScriptSerializer();
dynamic item = serializer.Deserialize<object>("{ \"test\":\"some data\" }");
string test= item["test"];
//test Result = "some data"
Newtonsoft is faster than java script serializer. ... this one depends on the Newtonsoft NuGet package, which is popular and better than the default serializer.
one line code solution.
var myclass = Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(Jsonstring);
Myclass oMyclass = Newtonsoft.Json.JsonConvert.DeserializeObject<Myclass>(Jsonstring);
You can accomplished your requirement easily by using Newtonsoft.Json library. I am writing down the one example below have a look into it.
Class for the type of object you receive:
public class User
{
public int ID { get; set; }
public string Name { get; set; }
}
Code:
static void Main(string[] args)
{
string json = "{\"ID\": 1, \"Name\": \"Abdullah\"}";
User user = JsonConvert.DeserializeObject<User>(json);
Console.ReadKey();
}
this is a very simple way to parse your json.
Here's a simple class I cobbled together from various posts.... It's been tested for about 15 minutes, but seems to work for my purposes. It uses JavascriptSerializer to do the work, which can be referenced in your app using the info detailed in this post.
The below code can be run in LinqPad to test it out by:
Right clicking on your script tab in LinqPad, and choosing "Query
Properties"
Referencing the "System.Web.Extensions.dll" in "Additional References"
Adding an "Additional Namespace Imports" of
"System.Web.Script.Serialization".
Hope it helps!

catch

// Probably means an invalid path (ie object doesn't exist)
}

}
}
As tripletdad99 said
var result = JsonConvert.DeserializeObject<T>(json);
but if you don't want to create an extra object you can make it with Dictionary instead
var result = JsonConvert.DeserializeObject<Dictionary<string, string>>(json_serializer);
add this ddl to reference to your project: System.Web.Extensions.dll
use this namespace: using System.Web.Script.Serialization;
public class IdName
{
public int Id { get; set; }
public string Name { get; set; }
}
string jsonStringSingle = "{'Id': 1, 'Name':'Thulasi Ram.S'}".Replace("'", "\"");
var entity = new JavaScriptSerializer().Deserialize<IdName>(jsonStringSingle);
string jsonStringCollection = "[{'Id': 2, 'Name':'Thulasi Ram.S'},{'Id': 2, 'Name':'Raja Ram.S'},{'Id': 3, 'Name':'Ram.S'}]".Replace("'", "\"");
var collection = new JavaScriptSerializer().Deserialize<IEnumerable<IdName>>(jsonStringCollection);
Copy your Json and paste at textbox on json2csharp and click on Generate button.
A cs class will be generated use that cs file as below
var generatedcsResponce = JsonConvert.DeserializeObject(yourJson);
Where RootObject is the name of the generated cs file;
Another fast and easy way to semi-automate these steps is to:
take the JSON you want to parse and paste it here: https://app.quicktype.io/ . Change language to C# in the drop down.
Update the name in the top left to your class name, it defaults to "Welcome".
In visual studio go to Website -> Manage Packages and use NuGet to add Json.Net from Newtonsoft.
app.quicktype.io generated serialize methods based on Newtonsoft.
Alternatively, you can now use code like:
WebClient client = new WebClient();
string myJSON = client.DownloadString("https://URL_FOR_JSON.com/JSON_STUFF");
var myClass = Newtonsoft.Json.JsonConvert.DeserializeObject(myJSON);
Convert a JSON string into an object in C#. Using below test case.. its worked for me. Here "MenuInfo" is my C# class object.
JsonTextReader reader = null;
try
{
WebClient webClient = new WebClient();
JObject result = JObject.Parse(webClient.DownloadString("YOUR URL"));
reader = new JsonTextReader(new System.IO.StringReader(result.ToString()));
reader.SupportMultipleContent = true;
}
catch(Exception)
{}
JsonSerializer serializer = new JsonSerializer();
MenuInfo menuInfo = serializer.Deserialize<MenuInfo>(reader);
First you have to include library like:
using System.Runtime.Serialization.Json;
DataContractJsonSerializer desc = new DataContractJsonSerializer(typeof(BlogSite));
string json = "{\"Description\":\"Share knowledge\",\"Name\":\"zahid\"}";
using (var ms = new MemoryStream(ASCIIEncoding.ASCII.GetBytes(json)))
{
BlogSite b = (BlogSite)desc.ReadObject(ms);
Console.WriteLine(b.Name);
Console.WriteLine(b.Description);
}
Let's assume you have a class name Student it has following fields and it has a method which will take JSON as a input and return a string Student Object.We can use JavaScriptSerializer here Convert JSON String To C# Object.std is a JSON string here.
public class Student
{
public string FirstName {get;set:}
public string LastName {get;set:}
public int[] Grades {get;set:}
}
public static Student ConvertToStudent(string std)
{
var serializer = new JavaScriptSerializer();
Return serializer.Deserialize<Student>(std);
}
Or, you can use the System.Text.Json library as follows:
using System.Text.Json;
...
var options = new JsonSerializerOptions()
{
PropertyNameCaseInsensitive = true
});
var result = JsonSerializer.Deserialize<List<T>>(json, options);
Where T is your object type that matches your JSON string.
System.Text.Json is available in:
.NET Core 2.0 and above
.NET Framework 4.6.1 and above
I just used the XmlWriter to create some XML to send back in an HTTP response. How would you create a JSON string. I assume you would just use a stringbuilder to build the JSON string and them format your response as JSON?
Using Newtonsoft.Json makes it really easier:
Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Price = 3.99M;
product.Sizes = new string[] { "Small", "Medium", "Large" };
string json = JsonConvert.SerializeObject(product);
Documentation: Serializing and Deserializing JSON
You could use the JavaScriptSerializer class, check this article to build an useful extension method.
Code from article:
namespace ExtensionMethods
{
public static class JSONHelper
{
public static string ToJSON(this object obj)
{
JavaScriptSerializer serializer = new JavaScriptSerializer();
return serializer.Serialize(obj);
}
public static string ToJSON(this object obj, int recursionDepth)
{
JavaScriptSerializer serializer = new JavaScriptSerializer();
serializer.RecursionLimit = recursionDepth;
return serializer.Serialize(obj);
}
}
}
Usage:
using ExtensionMethods;
...
List<Person> people = new List<Person>{
new Person{ID = 1, FirstName = "Scott", LastName = "Gurthie"},
new Person{ID = 2, FirstName = "Bill", LastName = "Gates"}
};
string jsonString = people.ToJSON();
Simlpe use of Newtonsoft.Json and Newtonsoft.Json.Linq libraries.
//Create my object
var myData = new
{
Host = #"sftp.myhost.gr",
UserName = "my_username",
Password = "my_password",
SourceDir = "/export/zip/mypath/",
FileName = "my_file.zip"
};
//Tranform it to Json object
string jsonData = JsonConvert.SerializeObject(myData);
//Print the Json object
Console.WriteLine(jsonData);
//Parse the json object
JObject jsonObject = JObject.Parse(jsonData);
//Print the parsed Json object
Console.WriteLine((string)jsonObject["Host"]);
Console.WriteLine((string)jsonObject["UserName"]);
Console.WriteLine((string)jsonObject["Password"]);
Console.WriteLine((string)jsonObject["SourceDir"]);
Console.WriteLine((string)jsonObject["FileName"]);
This library is very good for JSON from C#
http://james.newtonking.com/pages/json-net.aspx
This code snippet uses the DataContractJsonSerializer from System.Runtime.Serialization.Json in .NET 3.5.
public static string ToJson<T>(/* this */ T value, Encoding encoding)
{
var serializer = new DataContractJsonSerializer(typeof(T));
using (var stream = new MemoryStream())
{
using (var writer = JsonReaderWriterFactory.CreateJsonWriter(stream, encoding))
{
serializer.WriteObject(writer, value);
}
return encoding.GetString(stream.ToArray());
}
}
If you need complex result (embedded) create your own structure:
class templateRequest
{
public String[] registration_ids;
public Data data;
public class Data
{
public String message;
public String tickerText;
public String contentTitle;
public Data(String message, String tickerText, string contentTitle)
{
this.message = message;
this.tickerText = tickerText;
this.contentTitle = contentTitle;
}
};
}
and then you can obtain JSON string with calling
List<String> ids = new List<string>() { "id1", "id2" };
templateRequest request = new templeteRequest();
request.registration_ids = ids.ToArray();
request.data = new templateRequest.Data("Your message", "Your ticker", "Your content");
string json = new JavaScriptSerializer().Serialize(request);
The result will be like this:
json = "{\"registration_ids\":[\"id1\",\"id2\"],\"data\":{\"message\":\"Your message\",\"tickerText\":\"Your ticket\",\"contentTitle\":\"Your content\"}}"
Hope it helps!
You can also try my ServiceStack JsonSerializer it's the fastest .NET JSON serializer at the moment. It supports serializing DataContracts, any POCO Type, Interfaces, Late-bound objects including anonymous types, etc.
Basic Example
var customer = new Customer { Name="Joe Bloggs", Age=31 };
var json = JsonSerializer.SerializeToString(customer);
var fromJson = JsonSerializer.DeserializeFromString<Customer>(json);
Note: Only use Microsofts JavaScriptSerializer if performance is not important to you as I've had to leave it out of my benchmarks since its up to 40x-100x slower than the other JSON serializers.
Take a look at http://www.codeplex.com/json/ for the json-net.aspx project. Why re-invent the wheel?
If you want to avoid creating a class and create JSON then Create a dynamic Object and Serialize Object.
dynamic data = new ExpandoObject();
data.name = "kushal";
data.isActive = true;
// convert to JSON
string json = Newtonsoft.Json.JsonConvert.SerializeObject(data);
Read the JSON and deserialize like this:
// convert back to Object
dynamic output = Newtonsoft.Json.JsonConvert.DeserializeObject(json);
// read a particular value:
output.name.Value
ExpandoObject is from System.Dynamic namespace.
If you can't or don't want to use the two built-in JSON serializers (JavaScriptSerializer and DataContractJsonSerializer) you can try the JsonExSerializer library - I use it in a number of projects and works quite well.
If you're trying to create a web service to serve data over JSON to a web page, consider using the ASP.NET Ajax toolkit:
http://www.asp.net/learn/ajax/tutorial-05-cs.aspx
It will automatically convert your objects served over a webservice to json, and create the proxy class that you can use to connect to it.
Encode Usage
Simple object to JSON Array EncodeJsObjectArray()
public class dummyObject
{
public string fake { get; set; }
public int id { get; set; }
public dummyObject()
{
fake = "dummy";
id = 5;
}
public override string ToString()
{
StringBuilder sb = new StringBuilder();
sb.Append('[');
sb.Append(id);
sb.Append(',');
sb.Append(JSONEncoders.EncodeJsString(fake));
sb.Append(']');
return sb.ToString();
}
}
dummyObject[] dummys = new dummyObject[2];
dummys[0] = new dummyObject();
dummys[1] = new dummyObject();
dummys[0].fake = "mike";
dummys[0].id = 29;
string result = JSONEncoders.EncodeJsObjectArray(dummys);
Result:
[[29,"mike"],[5,"dummy"]]
Pretty Usage
Pretty print JSON Array PrettyPrintJson() string extension method
string input = "[14,4,[14,\"data\"],[[5,\"10.186.122.15\"],[6,\"10.186.122.16\"]]]";
string result = input.PrettyPrintJson();
Results is:
[
14,
4,
[
14,
"data"
],
[
[
5,
"10.186.122.15"
],
[
6,
"10.186.122.16"
]
]
]
The DataContractJSONSerializer will do everything for you with the same easy as the XMLSerializer. Its trivial to use this in a web app. If you are using WCF, you can specify its use with an attribute. The DataContractSerializer family is also very fast.
I've found that you don't need the serializer at all. If you return the object as a List.
Let me use an example.
In our asmx we get the data using the variable we passed along
// return data
[WebMethod(CacheDuration = 180)]
public List<latlon> GetData(int id)
{
var data = from p in db.property
where p.id == id
select new latlon
{
lat = p.lat,
lon = p.lon
};
return data.ToList();
}
public class latlon
{
public string lat { get; set; }
public string lon { get; set; }
}
Then using jquery we access the service, passing along that variable.
// get latlon
function getlatlon(propertyid) {
var mydata;
$.ajax({
url: "getData.asmx/GetLatLon",
type: "POST",
data: "{'id': '" + propertyid + "'}",
async: false,
contentType: "application/json;",
dataType: "json",
success: function (data, textStatus, jqXHR) { //
mydata = data;
},
error: function (xmlHttpRequest, textStatus, errorThrown) {
console.log(xmlHttpRequest.responseText);
console.log(textStatus);
console.log(errorThrown);
}
});
return mydata;
}
// call the function with your data
latlondata = getlatlon(id);
And we get our response.
{"d":[{"__type":"MapData+latlon","lat":"40.7031420","lon":"-80.6047970}]}
Include:
using System.Text.Json;
Then serialize your object_to_serialize like this:
JsonSerializer.Serialize(object_to_serialize)
