WCF -Rest- DataContract：反序列化XML包装的响应

Question

Assuming we are using a REST WCF service returning xml.

Is it possible to deserialize "automatically" an xml wrapped response to a DataContract ?

Simple example

Class:

[DataContract]
public class TestClass
{
    [DataMember]
    string StringValue { get; set; }
    [DataMember]
    int IntValue { get; set; }
}

Service:

[OperationContract]
[WebGet(UriTemplate = "Test",
   BodyStyle      = WebMessageBodyStyle.Wrapped,
   RequestFormat  = WebMessageFormat.Xml,
   ResponseFormat = WebMessageFormat.Xml)]
TestClass Test();

Client:

using (WebClient webClient = new WebClient())
{
    webClient.Headers["Content-type"] = "application/xml";
    webClient.Encoding = Encoding.UTF8;
    return webClient.DownloadString($"{BASE_URL}/Test");
}

Deserialization:

// With T as TestClass in or example.
public static T Deserialize<T>(string xml)
{
    using (Stream stream = new MemoryStream())
    {
        byte[] data = System.Text.Encoding.UTF8.GetBytes(xml);
        stream.Write(data, 0, data.Length);
        stream.Position = 0;
        DataContractSerializer deserializer =
             new DataContractSerializer(typeof(T));
        return (T)deserializer.ReadObject(stream);
    }
}

This code works well for bare response.

As webClient just return the full request, output xml contains thre wrapper element, and DataContractSerializer try parse a simple string, and don't now it come from WCF wrapped response (and should "forget" the wrapper).

Goal is to construct a client where wrapping style (bare/wrapped) doesn't matter.

why don't you just deserialize the output as a simple XML? something like this:

public static T XmlDeserializer<T>(string xmlString)
{
        var instance = default(T);
        var xmlSerializer = new XmlSerializer(typeof(T));
        using (var stringreader = new StringReader(xmlString))
            instance = (T)xmlSerializer.Deserialize(stringreader);

        return instance;
}

note: because of default xmlns tags you should use name space in your client side class like this:

[DataContract(Namespace = "http://schemas.datacontract.org/2004/07/WcfWebService")]
