Overloading webmethods

[Stuart Hemming (via DFN-CIS NetNews Service)]

Can I overload a webmethod?

Is there some special mechnism necessary to make this work? If I
compile something like this ...

--- START OF CODE ---
[WebMethod(Description="Call Process", EnableSession=true)]
public XmlElement MyMethod(string ProcessName) {
XmlDocument xml = new XmlDocument();

return xml.DocumentElement;
}

[WebMethod(Description="Call Process with input data", EnableSession=true)]
public XmlElement MyMethod(string ProcessName, XmlDocument UserData) {
XmlDocument xml = new XmlDocument();

return xml.DocumentElement;
}
--- END OF CODE ---
It compiles OK, but I get an exception when I try and access it.

Always remember you're unique, just like everyone else.

You can overload the method in the class file, but it must have a unique
message name. For example on your second overload you might put the
following:

[WebMethod(Description="Call Process with input data",
EnableSession=true,MessageName="MyMethod2")]
