I have the following sample C# code that is auto-genereated from an xsd using the svcutils.exe application.

 [DataContract] public enum Foo { [EnumMember(Value = "bar")] Bar = 1, [EnumMember(Value = "baz")] Baz = 2 } [DataContract] public class UNameIt { [DataMember(Name = "id")] public long Id { get; private set; } [DataMember(Name = "name")] public string Name { get; private set; } [DataMember(Name = "foo")] public Foo Foo { get; private set; } } 

The following is a unit test that attempts to deserialise a sample JSON document to the UNameIt class.

 [TestClass] public class JsonSerializer_Fixture { public const string JsonData = @"{ ""id"":123456, ""name"":""John Doe"", ""foo"":""Bar""}"; [TestMethod] public void DataObjectSimpleParseTest() { DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(UNameIt)); MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(JsonData)); UNameIt dataObject = serializer.ReadObject(ms) as UNameIt; Assert.IsNotNull(dataObject); Assert.AreEqual(123456, dataObject.Id); Assert.AreEqual(Foo.Baz, dataObject.Foo); } } 

Unfortunately, the test fails giving the following reason:

System.Runtime.Serialization.SerializationException: There was an error deserializing the object of type MyNamespace.Units.UNameIt. The value 'Bar' cannot be parsed as the type 'Int64'.

The test will pass if I update my JSON string to replace the string specifier for the Enum to an integer e.g.

public const string JsonData = @"{ ""id"":123456, ""name"":""John Doe"", ""foo"":""1""}"; 

I do not have the flexibility to the change the supplied JSON so I have to figure out how to convert the string Enum representation perhaps on serialisation. Ideally, I would like to facilitate this without having to change my autogenerate class because once I re-generate the class I would loose my changes.

I am wondering if it would be possible to extend the DataContractJsonSerializer to custom handle Enumerations? Or perhaps there is better way to do this?

Thanks, d
