How to set StreamingContext for DataContractSerializer?

Question

I have code like this:

[DataContract]
class Foo {
    [OnSerializing]
    private void BeforeSerialize(StreamingContext ctx)
    {
        ((MtType)ctx.Context).DoStuff()
    }

    ...
}

var reader = new XmlTextReader(filename);
var serializer = new DataContractSerializer(typeof(Type));
Type type = (Type)serializer.ReadObject(reader);

and I need to provide a structure StreamingContext. I found some links that this can be done for NetDataContractSerializer, but not for DataContractSerializer.

• Is there any way to make this work?
• Am I just doing it wrong?

Using IDataContractSurrogate allows you to perform custom JSON serialization and deserialization for each type or for each object.

See IDataContractSurrogate methods for API documents and see DataContract Surrogate for a sample.
