Validation of Web Method parameters

[bill dawson]

Is there any way, using declarative attributes, to specify the values that
are acceptable for the parameter of a web method? I would like to restrict
a parameter to certain values, and I'm interested in the best place to my
logic. The most convenient for me would be to make it an attribute and let
the WSDL take it into account automatically -- does such an attribute
exist?

There is nothing in the shipped CLR that provides exactly this. However,
there is a 2-part series of MSDN Magazine articles that provides an
excellent sample of how to validate parameters via a XML Schema and
declarative attributes.

Hope this helps,
