If I have a WebMethod that takes a parameter, what is the correct way to
validate it? I could throw an exception, but that does not seem right.

public DataSet TestMethod( string MyString )
{
// Validation Code
if ( MyString =="InvalidValue" )
Throw SoapException();

// Real code starts here
return ds;
}

Totally missed the post by Mark yesterday. I with the information posted
there unless anyone has any additional words of wisdom to add.

Thanks!

You could throw an exception, but any exception you throw comes back as a
SOAP exception. You could do one of the two things:

1. Throw a custom exception on the server-side, and parse the SOAP
exception's message on the client to check the name of the exception.

2. Use a helper class on the server to wrap the exception, and throw this
instead:
