why I cant deserlize json using datacontractserializer when using wrapped format - json

Question

My wcf service uses the wrapped format body style. When I try deserializing it using DataContractJsonSerializer isn't deserializing the json properly
SignInResult returnedUser = new SignInResult();
MemoryStream stream = new MemoryStream(Encoding.UTF8.GetBytes(provider.SignIn(username, password)));
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(SignInResult),"root");
returnedUser = serializer.ReadObject(stream) as SignInResult;
stream.Close();
return returnedUser;
but I don't get a object populated according to the following json
{
"SignInResult": {
"CreationDate": "/Date(1480598102923+0000)/",
"Email": "bladsa#as.com",
"IsApproved": true,
"IsLockedOut": false,
"IsOnline": true,
"IsValidLogin": true,
"LastActivityDate": "/Date(1490954750307+0100)/",
"LastLockoutDate": "/Date(-6816268800000+0000)/",
"LastLoginDate": "/Date(1490954750307+0100)/",
"LastPasswordChangedDate": "/Date(-2208988800000+0000)/",
"ProviderName": "LoginProvider",
"ProviderUserKey": "dcc5f38f-f71e-4d9d-bdb2-58fb60b7a65e",
"UserName": "schoi"
}
}
It does work if I use the bare format so it definately something to do with the wrapped message format.
I know I can do this in Newsoft json but I know I will get asked to use Microsofts way.

Answer 1

its so simple. at first we create a jsondeserilzer method like this:
public static T DataJsonDeserializer<T>(string jsonString)
{
var mStrm = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));
var jsonSerializer = new DataContractJsonSerializer(typeof(T));
var objResponse = jsonSerializer.ReadObject(mStrm);
return (T)objResponse;
}
then we create a json object like this:
public class SignInResult
{
public DateTime CreationDate { get; set; }
public string Email { get; set; }
public bool IsApproved { get; set; }
public bool IsLockedOut { get; set; }
public bool IsOnline { get; set; }
public bool IsValidLogin { get; set; }
public DateTime LastActivityDate { get; set; }
public DateTime LastLockoutDate { get; set; }
public DateTime LastLoginDate { get; set; }
public DateTime LastPasswordChangedDate { get; set; }
public string ProviderName { get; set; }
public string ProviderUserKey { get; set; }
public string UserName { get; set; }
}
public class RootObject
{
public SignInResult SignInResult { get; set; }
}
finally you can deserilze any thing like this:
var x = JsonDeserializer<RootObject>(provider.SignIn(username, password)));
