In your example, you're trying to call a function WriteText() from inside a
class where the function is not defined in the class of in any of it's
parents. This will not compile. Here're few ways you can call a function in
another class (c2) from inside your class (c1):
1. Create a member variable of type C2 inside class C1
2. Have C2 inherit from C1
3. Define the method inside C2 as static and then call using the Syntax
Class.Method()
4. Define a delegate of the same type as the function call in your class
C1 and on construction initialize the delegate to the original function
defined.
Hope this helps. If you tell me the exact scenario, I can give you some more
specific pointers
