How to Convert Json Result to Object in c# mvc

I am trying to convert this response to object so that i can use access them using object in c# mvc application.
Following is the code i did:
var response = await client.GetAsync("ApiTest?Amount=" + Amount.ToString() + "&WalletAddress=" + WalletAddress.ToString() + "&TokenCode=" + TokenType.ToString());
if (response.IsSuccessStatusCode)
{
result = response.Content.ReadAsStringAsync().Result;
var test1 = Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(result);
(Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(result));
result = await response.Content.ReadAsStringAsync();
var obj =Newtonsoft.Json.JsonConvert.DeserializeObject(result);
return Json(new { Message = "Your Transaction Has Been Completed Successfully!" }, JsonRequestBehavior.AllowGet);
}
Following is the Json response but its in string format:
{"Error":"Transaction amount must be greater than
0","Result":null,"IsSuccess":false,"HttpResponse":{"Headers":[{"Key":"X-Frame-Options","Value":["sameorigin"]},{"Key":"Strict-Transport-Security","Value":["max-age=31536000"]},{"Key":"Pragma","Value":["no-cache"]},{"Key":"Access-Control-Allow-Origin","Value":["*"]},{"Key":"Keep-Alive","Value":["timeout=5, max=100"]},{"Key":"Connection","Value":["Keep-Alive"]},{"Key":"Cache-Control","Value":["no-store,

any help would be highly appreciated>
Thanks

You can utilize Visual Studio's Paste Special feature:
Copy JSON and Paste Special:
You will get following classes:
public class JsonResponse
{
public string Error { get; set; }
public object Result { get; set; }
public bool IsSuccess { get; set; }
public Httpresponse HttpResponse { get; set; }
}
public class Httpresponse
{
public Header[] Headers { get; set; }
public string ContentBody { get; set; }
public int StatusCode { get; set; }
public bool IsSuccessStatusCode { get; set; }
public string RequestUri { get; set; }
public string RequestBody { get; set; }
}
public class Header
{
public string Key { get; set; }
public string[] Value { get; set; }
}
Now simply utilize Newtonsoft to deserialize:
var items = JsonConvert.DeserializeObject<JsonResponse>(json);
Output:

Try this:
using Newtonsoft.Json.Linq;
...
var jso = JObject.Parse(content);
string value = jso["propertyname"].Value<string>();

Cannot deserialize the current JSON array with metadata and records

Here is a sample of the JSON data I am getting back from a web service.
It has a single node of "odata.metadata", another single node of "value", and then the repeating records consisting of 3 fields "Code", "Name" and "XTag". This is in a string variable called Content
{"odata.metadata":"https://notthereal.domain:3148/system/OData/$metadata#pageLocationList","value":[{"Code":"LOC-A","Name":"Location A","XTag":"36;DgAAAAJ7/zEAMAAwAC0ATQBBAEkATgAAAAAA8;264943250;"},{"Code":"LOC-B","Name":"Location B","XTag":"36;DgAAAAJ7/zEAMAAxAC0ATQBBAEkATgAAAAAA8;388906690;"},{"Code":"LOC-C","Name":"Location C","XTag":"36;DgAAAAJ7/zEAMAAyAC0ATQBBAEkATgAAAAAA8;388844480;"},{"Code":"LOC-D","Name":"Location D","XTag":"36;DgAAAAJ7/zEAMAAzAC0ATQBBAEkATgAAAAAA8;388876720;"}]}
I have the following as the model, which I got by pasting the JSON data into the class.
public class ModelPageLocationList
{
public string odatametadata { get; set; }
public List<Value> value { get; set; }
}
public class Value
{
public string Code { get; set; }
public string Name { get; set; }
public string XTag { get; set; }
}
and this is the code trying to deserialise it...
DataPageLocationList =
JsonConvert.DeserializeObject<List<ModelPageLocationList>>(content);
..and this is the error message. I am stuck! Any ideas? I think the issue is around the 2 single records at the start, and then the repeating data after.
ERROR Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
Here is what I am calling
public async Task<List<ModelPageLocationList>> RefreshPageLocationListAsync ()
{
DataPageLocationList = new List<ModelPageLocationList>();
var uri = new Uri(string.Format(WebServiceSettings.WebServiceUrl, string.Empty));
try
{
var response = await client.GetAsync(uri);
if (response.IsSuccessStatusCode)
{
var content = await response.Content.ReadAsStringAsync();
Debug.WriteLine("{0}", content.ToString());
DataPageLocationList = JsonConvert.DeserializeObject<List<ModelPageLocationList>>(content);
}
} catch (Exception ex)
{
Debug.WriteLine(#"ERROR {0}", ex.Message);
}
return (DataPageLocationList);
}

Two things. Use JsonProperty to handle the odata.metadata property as the dot (.) in the property name will cause syntax problems.
public class ModelPageLocationList {
[JsonProperty("odata.metadata")]
public string odatametadata { get; set; }
[JsonProperty("value")]
public List<Value> value { get; set; }
}
Next based on the provided JSON example data you need to refactor the calling code
public async Task<ModelPageLocationList> RefreshPageLocationListAsync () {
try {
var uri = new Uri(string.Format(WebServiceSettings.WebServiceUrl, string.Empty));
var response = await client.GetAsync(uri);
if (response.IsSuccessStatusCode) {
var result = await response.Content.ReadAsAsync<ModelPageLocationList>();
return result;
}
} catch (Exception ex) {
Debug.WriteLine(#"ERROR {0}", ex.Message);
}
return null;
}

You need to serialize to your root object ModelPageLocationList, NOT a list of your root objects. Your JSON is an object not an array of objects. This will fix it:
DataPageLocationList =
JsonConvert.DeserializeObject<ModelPageLocationList>(content);

Without seeing the JSON Data you are trying to pass in, I can only provide two possible answers based on the information you have provided.
1) Make sure your JSON Looks like this:
{
"odatametadata": "SomeDataHere",
"value": [{
"code": "Code1",
"name": "Name1",
"xTag": "XTag1"
}, {
"code": "Code1",
"name": "Name1",
"xTag": "XTag1"
}, {
"code": "Code1",
"name": "Name1",
"xTag": "XTag1"
},
]
}
2 Add this attribute to your C# Class Model
public class ModelPageLocationList
{
[JsonProperty("odatametadata")]
public string odatametadata { get; set; }
[JsonProperty("value")]
public List<Value> value { get; set; }
}
public class Value
{
[JsonProperty("code")]
public string Code { get; set; }
[JsonProperty("name")]
public string Name { get; set; }
[JsonProperty("xTag")]
public string XTag { get; set; }
}

I did the following to get my code to work with the JSON data at the start of my post. Not ideal, and I would prefer to be able to do this without having to edit the JSON string.
public async Task<List<ModelPageLocationList>> RefreshPageLocationListAsync ()
{
DataPageLocationList = new List<ModelPageLocationList>();
var uri = new Uri(string.Format(WebServiceSettings.WebServiceUrl, string.Empty));
try
{
var response = await client.GetAsync(uri);
if (response.IsSuccessStatusCode)
{
var content = await response.Content.ReadAsStringAsync();
Debug.WriteLine("BEFORE {0}", content.ToString());
content = content.Substring(content.IndexOf('['), content.IndexOf(']') - content.IndexOf('[') + 1);
Debug.WriteLine("AFTER {0}", content.ToString());
DataPageLocationList = JsonConvert.DeserializeObject<List<ModelPageLocationList>>(content);
}
}
catch (Exception ex)
{
Debug.WriteLine(#"ERROR {0}", ex.Message);
}
return (DataPageLocationList);
}
and the class from the JSON data
public class ModelPageLocationList
{
public string Code { get; set; }
public string Name { get; set; }
public string ETag { get; set; }
}
Thanks everyone for their replies.

Additional information: Unable to cast object of type 'System.IO.MemoryStream' to type 'JsonData'

i have defined this class for decoding json response
private class JsonData
{
[JsonProperty(PropertyName = "api-author")]
public string apiauthor { get; set; }
[JsonProperty(PropertyName = "api-usage")]
public string apiusage { get; set; }
[JsonProperty(PropertyName = "status")]
public string status { get; set; }
[JsonProperty(PropertyName = "language")]
public string language { get; set; }
[JsonProperty(PropertyName = "sentiment-text")]
public string sentimenttext { get; set; }
[JsonProperty(PropertyName = "sentiment-score")]
public string sentimentscore { get; set; }
}
and i am trying to call an api
string url = "https://loudelement-free-natural-language-processing-service.p.mashape.com/nlp-text/?text=";
var response = Unirest.get(url)
.header("X-Mashape-Key", "AlZVYH30C9mshLPNM7KiE48aFfTHp1h3A31jsnmVPccxBzW5uB")
.header("Accept", "application/json")
.asJson<JsonData>()
.Body
;
var status = response.sentimenttext;
where i am getting this exception
An exception of type System.InvalidCastException' occurred in
unirest-net.dll but was not handled in user code
Additional information:
Unable to cast object of type 'System.IO.MemoryStream' to type
'JsonData'.

How about writing your own methods instead of using that library
public async Task<T> Get<T>(string url)
{
using (HttpClient client = new HttpClient())
{
client.DefaultRequestHeaders.TryAddWithoutValidation("X-Mashape-Key", "AlZVYH30C9mshLPNM7KiE48aFfTHp1h3A31jsnmVPccxBzW5uB");
client.DefaultRequestHeaders.TryAddWithoutValidation("Accept", "application/json");
var json = await client.GetStringAsync(url);
return JsonConvert.DeserializeObject<T>(json);
}
}
Now you can call it as
string url = "https://loudelement-free-natural-language-processing-service.p.mashape.com/nlp-text/?text=apple";
var jsonData = await Get<JsonData>(url);
Output:

C# Deserializing HttpResponseMessage to Object

I'm having some problem deserializeing a HttpResponseMessage into an object.
The problem is that when the object should have deserialized all fields are null, no exceptions are thrown.
HttpContent content = new StringContent(xml);
content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("text/xml");
HttpResponseMessage response = await client.PostAsync("URL", content).ConfigureAwait(false);
// Parse response
if (response.IsSuccessStatusCode)
{
XmlSerializer serializer = new XmlSerializer(typeof(ResponseObject));
Stream responseStream = await response.Content.ReadAsStreamAsync();
ResponseObject responseObject = serializer.Deserialize(responseStream) as ResponseObject;
//Possible example of wrong data
Console.WriteLine(responseObject.Message);
}
[XmlRoot("response")]
public class ResponseObject
{
[XmlElement("session")]
public string Session { get; set; }
[XmlElement("status")]
public string Status { get; set; }
[XmlElement("message")]
public string Message { get; set; }
}
Response message as a string
"<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>
<response>
<val n=\"session\">SESSION ID</val>
<val n=\"status\">201</val>
<val n=\"message\">Created</val>
</response>"
Have I missed something? I'm pretty new to serializing/deserializing.
Grateful for pointers.

Okay I solved it with the help of Eser and Biscuits in the comments.
I was trying to reuse code and did't really think about the response message having a different structure then the earlier project.
I changed my ResponseObject to this:
[XmlRoot("response")]
public abstract class ResponseObject
{
[XmlIgnore]
public bool Success { get; set; }
[XmlIgnore]
public string Session
{
get
{
var result = Values.FirstOrDefault(n => n.Name == "session");
return result.Value;
}
}
[XmlIgnore]
public string Status
{
get
{
var result = Values.FirstOrDefault(n => n.Name == "status");
return result.Value;
}
}
[XmlIgnore]
public string Message
{
get
{
var result = Values.FirstOrDefault(n => n.Name == "message");
return result.Value;
}
}
[XmlElement("val")]
public List<ResponseXmlWrapper<string>> Values;
}
public class ResponseXmlWrapper<T>
{
[XmlAttribute("n")]
[JsonProperty("n")]
public string Name { get; set; }
[XmlText]
[JsonProperty()]
public T Value { get; set; }
public ResponseXmlWrapper()
{
}
public ResponseXmlWrapper(string attributeName, T value)
{
Name = attributeName;
Value = value;
}
}
I don't know if this is an optimal solution but it works.

Send xml with a post request to wcf service on iis

SOLVED with this link
I'm developing a wcf service, with rest pattern. Now it is on a IIS server.
It has got a method callable with a post, which has to receive a xml data.
I'm trying to send this xml (with other parameter), but I'm getting only deserial errors:
in System.ServiceModel.Dispatcher.OperationFormatter.DeserializeRequest(Message message, Object[] parameters)
in System.ServiceModel.Dispatcher.DemultiplexingDispatchMessageFormatter.DeserializeRequest(Message message, Object[] parameters)
in System.ServiceModel.Dispatcher.UriTemplateDispatchFormatter.DeserializeRequest(Message message, Object[] parameters)
in System.ServiceModel.Dispatcher.DispatchOperationRuntime.DeserializeInputs(MessageRpc& rpc)
in System.ServiceModel.Dispatcher.DispatchOperationRuntime.InvokeBegin(MessageRpc& rpc)
in System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage5(MessageRpc& rpc)
in System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage31(MessageRpc& rpc)
in System.ServiceModel.Dispatcher.MessageRpc.Process(Boolean isOperationContextSet)
This is the request:

If you click here, you can find out how an xml is returned by my wcf. I thought I have to send the same xml with other data, but I get the deserial error.
Why?
How can I send the xml to my wcf? In this test phase, I'm using this.
If I can give to you other useful infos, ask me and I'll write them here.
UPDATE: The text of the error message says that there are invalid data at root level, row 1, pos 1. Also if I put
<?xml version="1.0" encoding="utf-8" ?>
at the root level.
Maybe are there some missing headers?
UPDATE server side:
this is how my server wcf is configured:
[OperationContract]
[WebGet(UriTemplate = "cliente.xml?retista={codret}&cliente={codiceCliente}&H={hashedString}", ResponseFormat = WebMessageFormat.Xml)]
List<WrapClienti> GetClienteXML(string codret, string codiceCliente, string hashedString);
and this is the called method:
public GenericResponse SetClientiXML(List<WrapClienti> clienti, string retista, string hashedString)
{
var api = new API();
return api.SetClienti(clienti, retista, hashedString);
}
as you can I see, I don't manage any xml/json deserialzing phase, it is managed by the wcf routine. For example, if I send a json list, it converts it to a List. This is what also with xml I want to see, but I'm getting the error at the top of this question.
ANOTHER UPDATE: I have to send 3 parameters in xml, so.... this is my last attempt, I think it is more correct than previouses. Now the server gives null reference error:
<?xml version="1.0" encoding="utf-8" ?>
<SetClientiXML
xmlns="http://tempuri.org/">
<XMLRequest>
<ArrayOfWrapClienti
xmlns="http://schemas.datacontract.org/2004/07/aaa"

</WrapClienti>
</ArrayOfWrapClienti>
<RETISTA>1111</RETISTA>

I have also created this class:
[DataContract]
public class XMLRequest
{
[DataMember]
public List<WrapClienti> XML;
[DataMember]
public string RETISTA;
[DataMember]
public string HASHEDSTRING;
public XMLRequest() { }
public XMLRequest(List<WrapClienti> x, string r, string h)
{
this.HASHEDSTRING = h;
this.XML = x;
this.RETISTA = r;
}
}
and the portotype now is:
public GenericResponse SetClientiXML(XMLRequest xr)

Does this work?
