c# - How to pass dictionary as part of the payload in POST request in Advanced Rest Client -

i trying use advanced rest client chrome extension testing webapi locally , pass dictionary part of payload post request trying make. while debugging found out dictionary though passing in json format doesn't deserialize correctly , count dictionary remains zero.

payload example :

{ "dictionaryforevaluationtelemetries" :{ "b":"{\"counter\":\"500\"}"} } 

this simple code object part of dictionary

[datacontract] class class1 {         private int counter;          [datamember]         public int counter         {             { return counter; }         }          public void increment()         {             interlocked.increment(ref counter);         } }  [datacontract] public class telemetrypayload {         [datamember]         public concurrentdictionary<string, class1> dictionaryforevaluationtelemetries { get; set; } }      [httppost]     public void logevaluationtelemetry()     { // internally below method :  jsonserializer<t>.deserialize(request.content.readasstringasync().result);                  var telemetrypayload = request.getobjectfrombody<telemetrypayload>();     } 

json deserialization done system.runtime.serialization.json

using system.io; using system.runtime.serialization.json; using system.text;  public static class jsonserializer<t> t : class {         public static t deserialize(string jsonobject)         {             byte[] array = encoding.utf8.getbytes(jsonobject);             using (memorystream ms = new memorystream(array))             {                 datacontractjsonserializer jsonserializer = new datacontractjsonserializer(typeof(t));                 return (t)jsonserializer.readobject(ms);             } } 

as far can tell json passing doesn't have object map class1. json should this:

{     "dictionaryforevaluationtelemetries" : {"b": {"counter": 500}} } 

where dictionaryforevaluationtelemetries.b map class1.

or, depending on request.getobjectfrombody<> method does, more this:

{"counter" : 500}
