Custom DataMember names to deserialize a JSON class

Question

I cannot manage to specify custom names for properties. I receive some JSON from the server (which I cannot change) with some ugly property names. I'd like the C# code to stick to naming conventions.

Below is the code I have (result0.StringValue stays null):

  [TestClass()]
  public class WebServiceResultConverterTest
  {
    [DataContract(Name = "SimpleObject")]
    private class SimpleObject
    {
        [DataMember(Name = "str_value")]
        public String StringValue { get; set; }

        [DataMember(Name = "int_value")]
        public String IntValue { get; set; }
    }

    [TestMethod()]
    public void DeserializeTest()
    {
        String input0 = @"{
          ""str_value"": ""This is a test string"",
          ""int_value"": 1664
        }";

        JavaScriptSerializer serializer = new JavaScriptSerializer();
        SimpleObject result0 = serializer.Deserialize<SimpleObject>(input0);

        Assert.AreEqual("This is a test string", result0.StringValue);
        Assert.AreEqual(1664, result0.IntValue);
    }
  }

You need to use the DataContractJsonSerializer with those attributes. I believe the JavascriptSerializer is now obsolete as of .Net 3.5.

Thanks, that works. Would there be any mean to specify some custom way of parsing the JSON for some of the data members? – Vincent Mimoun-Prat Sep 08 '11 at 15:35
It depends what sort of control you need. I find that JSON.NET http://json.codeplex.com/ allows for more control that the datacontract one. You can create `JSONConverter`s. Otherwise, you can create surrogate classes to define how to serialize using the data contract one - http://msdn.microsoft.com/en-us/library/system.runtime.serialization.idatacontractsurrogate.aspx – David Neale Sep 08 '11 at 16:01
