Passing a class to a web method

[Greg Merideth]

I ran into a small snag in passing in a class as a parameter to a web
method from our calling code.

Now, we routinely pass *back* as a return value from a method, a class
reference and that works just fine, it just seems we can't pass *to* a
web method a class as a parameter.

Here's what I mean

webserver -> monitor.asmx

public testMethod ( (IPInventory) _ipInvClass )
{
if(_ipInvClass. MemberA=="whate ver")
doSomething();
}

webclient -> testcall.cs

[iniitalize soap calls and stuff like that]

LocalIPInventor y.MemberA="what ever";
soapCall.testMe thod( (IPInventory) LocalIPInventor y );

Now, when the web service "monitor.as mx" gets to the if() part I get an
error indicating that I am attempting to use a value without it being
initialized.

The soap logger we have clearly shows *all* of the members of the
(IPInventory) class being sent to the method, its just the web method
won't place those values into the parameter class.

If we make the method return a type (IPInventory) and call it, the
client recieves a full class of type(IPInventor y) back and can use the
values.

So, why can't I pass a web method a class as a parameter yet I can
recieve it back from the method?

Anyone?
