Hi,

If the WebMethod is defined with ByRef parameters, it can returns values through these parameters (and becomes and two-way message).

But (obviously) nothing gets passed 'by reference' in the classic sense - i.e. a pointer to the data. All that happens is that .NET automatically includes elements for the byRef data in the return SOAP message. Unless the method in question is also used as a non-webservice method I can't see much point in this construct.
