RESTful web service body format

Question

I am new to WCF. I am doing some simple RESTful WCF operation contracts. And, I have a question about options for property BodyS

Answer 1

The usage of the wrapped on the operation description simply wraps the request (or the response) in an XML element. For example, in this contract:

[ServiceContract]
public interface ITest
{
    [OperationContract]
    [WebInvoke(BodyStyle = WebMessageBodyStyle.Bare)]
    string Echo(string text);

    [OperationContract]
    [WebInvoke(BodyStyle = WebMessageBodyStyle.Wrapped)]
    string EchoWrapped(string text);

    [OperationContract]
    [WebInvoke(BodyStyle = WebMessageBodyStyle.Wrapped)]
    int Divide(int dividend, int divisor, out int reminder);
}

The input for the Echo operation is simply a element, with the text contained within. Likewise, its response contains a single element with the return of the operation. For the EchoWrapped operation, the input is actually a element, whose child is a element whose child contains the input to the method.

What a service expects for the Echo operation:

What a service expects for the EchoWrapped operation:
