I am trying to deserialize the following JSON file into 3 variables:
manager(Class)
Servers(list-class)
Admins(List-Class)
Everything I've tried so far doesn't work. How should I do that?
{
"Manager":{
"ServerIp":"ServerIP",
"ServerPort":"6000"
},
"Admins":[
{
"Name":"AdminUserName",
"ID":"AdminID"
}
]
"Servers":[
{
"ServerName":"servername",
"Path":"executablepath",
"IP":"ip",
"Port":"port",
"Password":"pass"
}
]
}
public class Manager
{
public string? ServerIp { get; set; }
public string? ServerPort { get; set; }
}
public class Admins
{
public string? Name { get; set; }
public string? ID { get; set; }
}
public class Servers
{
public string? ServerName { get; set; }
public string? Path { get; set; }
public string? IP { get; set; }
public string? Port { get; set; }
public string? Password { get; set; }
}
Add another class that precisely matches the structure of the JSON that you're describing:
public class Info // come up with a better name than "Info"...
{
public Manager Manager { get; set; }
public List<Admins> Admins { get; set; }
public List<Servers> Servers { get; set; }
}
Then just deserialize the contents of this file into an instance of this class, for example (using System.Text.Json):
var json = File.ReadAllText(pathToFile);
var info = JsonSerializer.Deserialize<Info>(json);
Then just read the properties of info as you need them (Manager, etc.).
here is an equivalent JSON model to your desired C# types. Nullable types are not recommended to use while working with JSON to C# Models.

I have a json file, where i have to validate a json attribute element value based on another json element attribute value. But if there json elements with the same name. It always takes the last value always instead of parsing the json data fully. Please guide me.
Below the sample json file
{
"PLMXML":{
"language":"en-us",
"author":"Developer",
"date":"2020-05-22",
"traverseRootRefs":"#id6",
"Operation":{
"id":"id21",
"subType":"BS4_BaOP",
"catalogueId":"70700000209604"
},
"Operation":{
"id":"id28",
"subType":"BS4_BaOP",
"catalogueId":"70700000209603"
},
"OperationRevision":{
"id":"id6",
"subType":"BS4_BaOPRevision",
"masterRef":"#id21",
"revision":"A1"
}
}
}
And below the code which im trying to use
public void Readjsonfile(string jsondata)
{
var message = JsonConvert.DeserializeObject<plmxmldatamodel>(jsondata);
if (String.Equals(message.PLMXML.traverseRootRefs.Substring(1), message.PLMXML.OperationRevision.id))
{
Console.WriteLine("Condtion1");
if (String.Equals(message.PLMXML.OperationRevision.masterRef.Substring(1), message.PLMXML.Operation.id))
{
Console.WriteLine("Condition_2");
//Do something based on the condtion
}
}
}
public class Operation
{
public string id { get; set; }
public string subType { get; set; }
public string catalogueId { get; set; }
}
public class OperationRevision
{
public string id { get; set; }
public string subType { get; set; }
public string masterRef { get; set; }
}
public class PLMXML
{
public string language { get; set; }
public string author { get; set; }
public string date { get; set; }
public string traverseRootRefs { get; set; }
public Operation Operation { get; set; }
public OperationRevision OperationRevision { get; set; }
}
public class plmxmldatamodel
{
public PLMXML PLMXML { get; set; }
}
When i try to dedug this in the second if condtion, the value for message.PLMXML.Operation.id is always id28 , because of which second if condition fails. While the first if condition is passed as there is only one message.PLMXML.OperationRevision.id. i wanted behaviour where it would check complete json data and check if message.PLMXML.Operation.id with value id21 is present or not , So my data gets passed. Please kindly guide me here.I am very new to C# here.
From my observation you have couple of issues.
What happen you have double keys, and your parser taking the last value not the first one.
First of all your json should be corrected. I assume you have access to change your json and operation should be an array like follow:
{
"PLMXML":{
"language":"en-us",
"author":"Developer",
"date":"2020-05-22",
"traverseRootRefs":"#id6",
"Operations":[
{
"id":"id21",
"subType":"BS4_BaOP",
"catalogueId":"70700000209604"
},
{
"id":"id28",
"subType":"BS4_BaOP",
"catalogueId":"70700000209603"
}
],
"OperationRevision":{
"id":"id6",
"subType":"BS4_BaOPRevision",
"masterRef":"#id21",
"revision":"A1"
}
}
}
When array in place than use an online tool like to validate your json and use this tool to create a model.
Your model will be like this:
public partial class PlmxmlDataModel
{
[JsonProperty("PLMXML")]
public Plmxml Plmxml { get; set; }
}
public partial class Plmxml
{
[JsonProperty("language")]
public string Language { get; set; }
[JsonProperty("author")]
public string Author { get; set; }
[JsonProperty("date")]
public DateTimeOffset Date { get; set; }
[JsonProperty("traverseRootRefs")]
public string TraverseRootRefs { get; set; }
[JsonProperty("Operations")]
public Operation[] Operations { get; set; }
[JsonProperty("OperationRevision")]
public OperationRevision OperationRevision { get; set; }
}
public partial class OperationRevision
{
[JsonProperty("id")]
public string Id { get; set; }
[JsonProperty("subType")]
public string SubType { get; set; }
[JsonProperty("masterRef")]
public string MasterRef { get; set; }
[JsonProperty("revision")]
public string Revision { get; set; }
}
public partial class Operation
{
[JsonProperty("id")]
public string Id { get; set; }
[JsonProperty("subType")]
public string SubType { get; set; }
[JsonProperty("catalogueId")]
public string CatalogueId { get; set; }
}
And your method like this:
public void Readjsonfile(string jsondata)
{
var message = JsonConvert.DeserializeObject<PlmxmlDataModel>(jsondata);
if (String.Equals(message.Plmxml.TraverseRootRefs.Substring(1), message.Plmxml.OperationRevision.Id))
{
Console.WriteLine("Condtion1");
if (String.Equals(message.Plmxml.OperationRevision.MasterRef.Substring(1), message.Plmxml.Operations[0].Id))
{
Console.WriteLine("Condition_2");
//Do something based on the condtion
}
}
}
Now in your method I am looking for array index 0 with contain id 28, but if you are look for id 28 in any of the array then you can do some thing like:
if (message.Plmxml.Operations.Any(e => e.Id == message.Plmxml.OperationRevision.MasterRef.Substring(1)))
I have a task to fetch the list of all missing updates using a C# .NET Framwork 4.7.2 windows Service which runs at specific intervals.
I have gotten this far to Fetch the Missing updates following this Answer.
Now I need to Put all the Fetched data in a JSON file using the following Format:
{
"hostName": "LRD-SomeHost",
"ip" : "192.168.13.12",
"mac" : "MAC:23:23:123:AS"
"timeStamp" : "CURRENT_TIME_STAMP",
"updates" : [
{
"updateID": "b32e464f-2e4a-4109-9018-33583a079a8a",
"updateDetails": [
{
"patchDescription" : "Some Long Description",
"patchCategory" : "28bc880e-0592-4cbf-8f95-c79b17911d5f"
"patchType" : "UpdateClassification"
"patchName" : "Update Rollups"
},
{
"patchDescription" : "Windows 10"
"patchCategory" : "a3c2375d-0c8a-42f9-bce0-28333e198407"
"patchType" : "Product"
"patchName" : "Windows 10"
},
{
"patchDescription" : "Windows 10 LTSB"
"patchCategory" : "d2085b71-5f1f-43a9-880d-ed159016d5c6"
"patchType" : "Product"
"patchName" : "Windows 10 LTSB"
}
]
}
]
}
Following is my C# Model:
namespace UpdateCollector
{
public class Host
{
public string hostname { get; set; }
public string ip { get; set; }
public string mac { get; set; }
public DateTime? timeStamp { get; set; }
public List<Updates> updates { get; set; }
}
public class Updates
{
public string updateID { get; set; }
public List<UpdateDetails> updateDetails { get; set; }
}
public class UpdateDetails
{
public string patchDescription { get; set; }
public string patchCategory { get; set; }
public string patchType { get; set; }
public string patchName { get; set; }
}
}
My Question is How to put my C# Data in this Format?
Thanks
You could use Json.NET to achieve this, here is a possible implementation:
First you need to install the package using NuGet:
Install-Package Newtonsoft.Json -Version 12.0.3
Then you define your classes in the same way you are doing, you can, however, use C# naming conventions and make use of attributes to specify different names for serialization:
public class Host
{
[JsonProperty(PropertyName = "hostname")]
public string Hostname { get; set; }
[JsonProperty(PropertyName = "ip")]
public string Ip { get; set; }
[JsonProperty(PropertyName = "mac")]
public string Mac { get; set; }
[JsonProperty(PropertyName = "timeStamp")]
public DateTime? TimeStamp { get; set; }
[JsonProperty(PropertyName = "updates")]
public List<Updates> Updates { get; set; }
}
public class Updates
{
[JsonProperty(PropertyName = "updateID")]
public string UpdateId { get; set; }
[JsonProperty(PropertyName = "updateDetails")]
public List<UpdateDetails> UpdateDetails { get; set; }
}
public class UpdateDetails
{
[JsonProperty(PropertyName = "patchDescription")]
public string PatchDescription { get; set; }
[JsonProperty(PropertyName = "patchCategory")]
public string PatchCategory { get; set; }
[JsonProperty(PropertyName = "patchType")]
public string PatchType { get; set; }
[JsonProperty(PropertyName = "patchName")]
public string PatchName { get; set; }
}
To serialize your class to json you can use the following statement:
var host = new Host();
// Fill all the properties, lists etc...
string json = JsonConvert.SerializeObject(host, Formatting.Indented);
To deserialize a json string back to the a C# object you use the opposite statement:
Host host = JsonConvert.DeserializeObject<Host>(json);
The code above should work for most cases but if you need to serialize / deserialize any of your objects in a special way you can write a custom JsonConverter: see here for an example.
Install Newtonsoft.Json package and do serialization of your object.
follow below code example.
List<Host> dataList=new List<Host>();
string jsonString = JsonConvert.SerializeObject(dataList);
I have been trying to get this json to deserialize for two days now using RestSharp. I have gone through the RestSharp github site, looked at countless examples, and spent much time here on Stack Overflow to try and find the answer to no avail. My code had previously worked perfectly but the vendor changed their API version and I was forced to do an update to keep using the application for my legal practice. My json is as follows(client info has been removed and replaced with generic info):
{
"data":[
{
"id":1035117666,
"client":
{
"id":905422394,
"name":"client1"
},
"display_number":"11-00012",
"description":"General",
"practice_area":
{
"id":4269978,
"name":"Business"
},
"status":"Open",
"open_date":"2011-12-14",
"close_date":null,
"billing_method":"hourly"
},
{
"id":1035117768,
"client":
{
"id":905422506,
"name":"client2"
},
"display_number":"12-00037",
"description":"HOA",
"practice_area":
{
"id":4269978,
"name":"Business"
},
"status":"Open",
"open_date":"2012-08-07",
"close_date":null,
"billing_method":"hourly"
}
],
"meta":
{
"paging":
{
"next":"https://app.goclio.com/api/v4/matters.json?fields=id%2C+client%7Bid%2C+name%7D%2C+display_number%2C+description%2C+practice_area%7Bid%2C+name%7D%2C+status%2C+open_date%2C+close_date%2C+billing_method&limit=2&page_token=BAh7BjoLb2Zmc2V0aQc%3D--b1ea3eba20c8acefbcdfc7868debd1e0ee630c64&status=Open"
},
"records":91
}
}
I built the following schema within my c# code:
public class MatterList
{
public List<Matter> matters { get; set; }
public Meta meta { get; set; }
}
public class Meta
{
public Paging paging { get; set; }
public int records { get; set; }
}
public class Paging
{
public string previous { get; set; }
public string next { get; set; }
}
[DeserializeAs(Name = "data")]
public class Matter
{
public int id { get; set; }
public Client client { get; set; }
public string display_number { get; set; }
public string description { get; set; }
public PracticeArea practice_area { get; set; }
public string status { get; set; }
public DateTime open_date { get; set; }
public DateTime close_date { get; set; }
public string billing_method { get; set; }
public string type = "matter";
}
public class PracticeArea
{
public int id { get; set; }
public string name { get; set; }
}
public class Client
{
public int id { get; set; }
public string name { get; set; }
}
When I run the RestSharp deserialize method I am sending the result to an object of type MatterList using the following line of code
MatterList matterList = jsonHandler.Deserialize<MatterList>(response);
I have so far attempted to deserialize without the Meta or Paging POCO classes with the accompanying change to the MatterList class (taking out the Meta property).
I have tried with and without the [DeserializeAs(Name="data")] directive.
I have tried to set the RootElement of the json response prior to deserialization.
I have tried to shorthand the deserialization by combining it with the Execute request code
IRestResponse<MatterList> matterList = client.Execute<MatterList>(request);
I have created a container class called MatterContainer which I placed between MatterList and Matter classes in the schema:
public class MatterList
{
public List<MatterContainer> matters { get; set; }
}
public class MatterContainer
{
public Matter matter { get; set; }
}
public class Matter
{
public int id { get; set; }
public Client client { get; set; }
public string display_number { get; set; }
public string description { get; set; }
public PracticeArea practice_area { get; set; }
public string status { get; set; }
public DateTime open_date { get; set; }
public DateTime close_date { get; set; }
public string billing_method { get; set; }
public string type = "matter";
}
I know I am getting the json response back from the server correctly so my request is proper and MatterList is not null after deserialization. The problem is that I cannot get the deserialization to actually populate the List matters within the MatterList class.
I have been looking at this off and on for two days and cannot get past this hurdle. If anyone sees what I did wrong I would greatly appreciate the insight, I am at a point where I cannot progress further with my application.
Thanks!
I think your [DeserializeAs(Name = "data")] attribute is in the wrong place. Try putting it in the root class instead:
public class MatterList
{
[DeserializeAs(Name = "data")]
public List<Matter> matters { get; set; }
public Meta meta { get; set; }
}
alternatively, try renameing that property to data
I'm using the API of www.textlocal.in, which returns a JSON formatted object.
JSON
{
"warnings":[
{
"message":"Number is in DND",
"numbers":"917000000000"
}
],

"cost":1,
"num_messages":1,

],
"messages":[
{
"id":"1350123781",
"recipient":918819437284
}
],
"status":"success"
}
My code with which I'm trying to parse the JSON:
private void button1_Click(object sender, EventArgs e)
{
var a = JsonConvert.DeserializeObject<List<jsonToObj[]>>(richTextBox1.Text);
}
public class jsonToObj
{
public warnings[] warnings { get; set; }
public int balance { get; set; }
public int batch_id { get; set; }
public int cost { get; set; }
public int num_messages { get; set; }
public message message { get; set; }
public string receipt_url { get; set; }
public string custom { get; set; }
public messages[] messages { get; set; }
public string status { get; set; }
}
public class warnings
{
public string message { get; set; }
public string numbers { get; set; }
}
public class messages
{
public string id { get; set; }
public int recipient { get; set; }
}
public class message
{
public int num_part { get; set; }
public string sender { get; set; }
public string content { get; set; }
}
I'm getting an exception with the following message:
Newtonsoft.Json.JsonSerializationException: 'Cannot deserialize the
current JSON object (e.g. {"name":"value"}) into type
'System.Collections.Generic.List`1[WindowsFormsApp1.Form2+jsonToObj[]]'
because the type requires a JSON array (e.g. [1,2,3]) to deserialize
correctly. To fix this error either change the JSON to a JSON array
(e.g. [1,2,3]) or change the deserialized type so that it is a normal
.NET type (e.g. not a primitive type like integer, not a collection
type like an array or List) that can be deserialized from a JSON
object. JsonObjectAttribute can also be added to the type to force it
to deserialize from a JSON object. Path 'warnings', line 1, position
12.'
First of all you have to figure out what your API returns.
Right now you're trying to parse a List of jsonToObj Arrays (List<jsonToObj[]>). You have to decide whether to use a jsonToObj[] or List<jsonToObj> or a simple jsonToObj which your API provides now:
var a = JsonConvert.DeserializeObject<jsonToObj>(richTextBox1.Text);
But this then throws:
JSON integer 918819437284 is too large or small for an Int32. Path 'messages[0].recipient', line 25, position 33."
So make sure you use a Long for that.
public class messages
{
public string id { get; set; }
public long recipient { get; set; }
}
Furthermore you can add inDND to your jsonToObj class if you need the info:
public class jsonToObj
{
...
public string[] inDND { get; set; }
...
}
Based on string you class structure should be like this :
public class Warning
{
public string message { get; set; }
public string numbers { get; set; }
}
public class Message
{
public int num_parts { get; set; }
public string sender { get; set; }
public string content { get; set; }
}
public class Message2
{
public string id { get; set; }
public long recipient { get; set; }
}
public class RootObject
{
public List<Warning> warnings { get; set; }
public int balance { get; set; }
public int batch_id { get; set; }
public int cost { get; set; }
public int num_messages { get; set; }
public Message message { get; set; }
public string receipt_url { get; set; }
public string custom { get; set; }
public List<string> inDND { get; set; }
public List<Message2> messages { get; set; }
public string status { get; set; }
}
It looks like your class structure is not proper, Make use of visual studio and generate C# class from json string and then using that generated class try to deserialize class.
Read : Visual Studio Generate Class From JSON or XML
I simulated your problem and made the following changes that worked:
Change the method that deserializes to this:
var a = JsonConvert.DeserializeObject<jsonToObj>(richTextBox1.Text);
The result of the JSON you receive is not a List, so it will not work to deserialize to List<>.
The recipient property of the messages class receives values larger than an integer, so it must be transformed into a long like this:
public long recipient { get; set; }
These changes solve your problem.
Looks like this is a very old post, still thought of answering.
First of all, your Json data is singular which means, either
var a = JsonConvert.DeserializeObject<List<jsonToObj[]>>(richTextBox1.Text);
or
var a = JsonConvert.DeserializeObject<List<jsonToObj>>(richTextBox1.Text);
may not work for you.
You can either try:
var a = JsonConvert.DeserializeObject<jsonToObj>(richTextBox1.Text);
or
enclose the data with [ and ], which would do the trick.
make sure your parsing single object vs list of objects.
I am setting a class in C# to hold a response that I will be receiving from a web service call. I'm using RestSharp to handle the calling / parsing of the JSON data.
The web service documentation describes the response as:
OUTPUT: JSON object similar to example below.
{
"response":"[success] or [failed]",
"messages":"Process succeeded.",
"logonkey":"[logon key]",
"tokenkey":"[security token]",
"reccount":"1",
"filelist":
{
"fileid":"12345",
"status":"N",
"filename":"data.tar",
"fulfilled":"2012-06-15"
}
}
My question is how can I define the filelist array element in my class?
I was thinking something like this:
public class Files
{
public string Response { get; set; }
public string Messages { get; set; }
public string LogonKey { get; set; }
public string TokenKey { get; set; }
public int RecordCount { get; set; }
public List<FileList>
}
public class FileList
{
public string FileID { get; set; }
public string Status { get; set; }
public string Filename { get; set; }
public DateTime Fulfilled { get; set; }
}
However, I'm having a problem with the "public List" statement.
Any suggestions on the best way to handle this scenario would be appreciated.
Also you forgot to give it a name, for example try this
public List<FileList> MyFavouriteList {get;set;}.
A proprety is declared like this "access modifier", "Type", "identifier(or name)", "getter and setter".
The filelist in JSON sample doesn't look like list of objects. Instead it is a single object.
You could try,
public class Files
{
public string Response { get; set; }
public string Messages { get; set; }
public string LogonKey { get; set; }
public string TokenKey { get; set; }
public int RecordCount { get; set; }
public FileList File {get; set; }
}
If you are sure the filelist in JSON is really list of object, you could try,
public List<FileList> Files = new List<FileList>();
