How to deserialize JSON string is correct in c#?

Question

Help to deal with JSON deserialization correct answer. For example, we have JSON response to the following:

{"variant":"otvet1",
 "source":"otvet2",
 "items":[
          {"list":"512"},
          {"vist":"315"},
          {"zist":"561"}]}

To deserialize using the following code:

  [DataContract]
    public partial class ItemsList
    {
        [DataMember(Name = "list")]
        public string lisType { get; set; }

        [DataMember(Name = "vist")]
        public string vistType { get; set; }

        [DataMember(Name = "zist")]
        public string zistType { get; set; }
    }

    [DataContract]
    public partial class SourceList
    {
        [DataMember(Name = "variant")]
        public string variantType { get; set; }

        [DataMember(Name = "source")]
        public string vistType { get; set; }

        [DataMember(Name = "items")]
        public List <ItemsList> TestItemsList { get; set; }
    }

    public class JsonStringSerializer
    {
        public static T Deserialize<T>(string strData) where T : class
        {
            MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(strData));
            DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
            T tRet = (T)ser.ReadObject(ms);
            ms.Close();
            return (tRet);
        }
    }

    private static SourceList SourceTempList;
    SourceTempList = JsonStringSerializer.Deserialize<SourceList>(e.Result); //in e.Result JSON response

In the previous code, it works, but if you change the JSON response, it does not work ... New JSON response:

{"variant":"otvet1",
 "source":"otvet2",
 "items":[3,
          {"list":"512"},
          {"vist":"315"},
          {"zist":"561"}]}

In this case, c # code for deserialization does not work ... Items in the number 3 appeared, tell me how to deserialize the JSON response to this? Were available to list vist and zist ...Help me...please

Historically the DataContractJsonSerializer has been seen as broken. The reccomendation is to use JSON.Net http://james.newtonking.com/projects/json-net.aspx
