This attribute is used to bind methods in an HttpGetClientProtocol or HttpPostClientProtocol proxy class to web service methods.

The ParameterFormatter property specifies how the proxy encodes parameters before sending them to a web service method. The ReturnFormatter property specifies how the proxy class decodes the web method's return value. Both values must be set, as there is no default value. Set ReturnFormatter to the UrlParameterWriter type if you are using HTTP GET or the HtmlFormParameterWriter type if you are using HTTP POST. Always set ParameterFormatter to the XmlReturnReader type. An example attribute declaration for HTTP GET is <HttpMethodAttribute(GetType(XmlReturnReader), GetType(UrlParameterWriter))>.

public sealed class HttpMethodAttribute : Attribute {
// Public Constructors
   public HttpMethodAttribute( );
   public HttpMethodAttribute(Type returnFormatter, Type parameterFormatter);
// Public Instance Properties
   public Type ParameterFormatter{set; get; }
   public Type ReturnFormatter{set; get; }
}
