c# - DataContractJsonSerializer exception -

i getting error when using class.

error

expecting element 'root' namespace ''.. encountered 'none' name '', namespace

my class

[datacontract] public class entrydata {     [datamember]     public string entryid { get; set; }      [datamember]     public string emailaddress { get; set; }      [datamember]     public string statuscode { get; set; }      [datamember]     public string totalvotecount { get; set; }      public static t deserialise<t>(string json)     {         var obj = activator.createinstance<t>();         using (var memorystream = new memorystream(encoding.unicode.getbytes(json)))         {             memorystream.position = 0;             var serializer = new datacontractjsonserializer(obj.gettype());             obj = (t)serializer.readobject(memorystream); // getting exception here                                 return obj;         }     } } 

usage

string responsejson = new streamreader(httpcontext.current.request.inputstream).readtoend(); var results = entrydata.deserialise<entrydata>(response) 

i have seen online has memorystream position can see setting beginning.

please help.

json going handler

i don't set statuscode or totalvotecount when passing json in. don't think problem though.

{     "entryid":"43",     "emailaddress":"test@email.com" } 

answer

instead of using deserialize method in class using this.

//commented out code.         string responsejson = new streamreader(httpcontext.current.request.inputstream).readtoend(); var results = entrydata.deserialise<entrydata>(response)  // way go using javascriptserializer    var serializer = new javascriptserializer(); var results = serializer.deserialize<entrydata>(response); 

could caused json names not matching property names in c#?

my understanding that

{      "firstname" : "mark" } 

would able deserialize into:

[datacontract] public class person  {          [datamember]      public string firstname {get; set;} } 

but wouldn't able serialize

{      "name" : "mark" } 

unless changed c# class have explicit name datamember

[datacontract] public class person  {          [datamember(name="name")]      public string firstname {get; set;} } 

i'm not sure error cause though. don't have enough first hand experience.
