The SoapRpcServiceAttribute allows you to set the default encoding style for XML Web service methods within an XML Web service to RPC method encoding and Encoded parameter encoding.

Web Services Description Language (WSDL) defines two styles for how an XML Web service method, or operation, can be encoded in a SOAP request or a SOAP response: RPC and Document. The RPC style refers to encoding the XML Web service method according to section 7 of the SOAP specification for using SOAP for RPC. This style specifies that all parameters are encapsulated within a single element named after the XML Web service method, and that each element within that element represents a parameter named after its respective parameter name.

To set the default method level encoding to Document, apply a SoapDocumentServiceAttribute to the class implementing the XML Web service.

For more details, see Customizing SOAP Message Formatting.

This attribute can be applied to a class implementing an XML Web service.

The following example shows how to use the SoapRpcServiceAttribute class.

<%@ WebService Language="c#" Class="SumService" %>

using System;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Web.Services.Description;

	public class SumService : System.Web.Services.WebService
		public int Add(int a, int b)
			return a + b;
