how to call webservice with ref?

[veger]

I am calling a webservice that will return multiple integer values, so I assume the best way to do so is pass the variables by ref, right?

 

So I define my variables, and call the webservice...

 int foo;
 ret = mywebservice.mymethod( ref foo);

But I get a compilation error: "use of unassigned local variable 'foo'"

 

Since the purpose of the webservice function is to populate foo, surely I don't have to populate foo before calling the function?

Either initialize the variable with an initial value, or use the out parameters. I recommend you look through MSDN to check the differences between the two.

int hello = 10;
DoHello(ref hello);

You could also create a class that exposes the returned values as properties and return an instance of the class.
