DataContract question: Support for returning XmlDocument to client

Question

Hi,

I have a service method which returns xml document to client. If I have this method, then service is returning error:

"The service encountered an error while generating metadata. See the trace files for more details."

My code is:

[ServiceContract]

public interface IMyService

{

[OperationContract]

MyXmlData GetInstructionSumaryXmlDoc();

}

 

[DataContract]

public class MyXmlData

{

[DataMember]

public XmlDocument Data;

}

Is there any thing wrong in the above code?

Thanks in Advance,

Venkat

Answer 1

You will need to add the [XmlSerializerFormat] attribute.

So (without using Datacontract although you can use that too):

[ServiceContract(Namespace = "urn:SerializationTest")]

[XmlSerializerFormat]

public interface IBlah

{

[OperationContract]

XmlDocument Returnxmldoc();

}

Thanks!  I had the same problem and have been banging my head on the keyboard all day, but that fixed it!
