Questions tagged [webmethod]

WebMethod is an attribute that is marked to indicate that a function (usually in .NET) in a web service is exposed to the consumers of the web service.

The WebMethod attribute is attached to a public method (cannot be attached to a private/protected) that you want the method exposed as part of the .NET Web service. It is also used to further configure the behavior of the method by passing additional attributes. Check out the MSDN link for more information, How to: Use the WebMethod Attribute.
