Custom objects as web methods parameters

[Diego F.]

I'm having a problem that I can't solve.

- I wrote a library with a class that has some numeric attributes and an
ArrayList; more or less:

public class myClass
{
private int number;
private ArrayList list;

public myClass(){}
public myClass(int n, ArrayList l)
{
number = n;
list = l;
}
}

I compiled it into a DLL so I can reuse it.

- Then I wrote a web service that has to use this class in some web methods,
like:
[WebMethod]
public void newObject(myClass obj) {...}

- Finally I have the application that use the web service. I use a reference
for the DLL and a web reference for the web service. I declare an object of
myClass and then try to pass it as the paremeter to the web service, but I
get a compilation error because it expects to receive an object with the
type of the web method (?). The problem is that the type of myClass is now
associated to the web service, and not to the DLL separately.

What should I do?
