  • Does it include dynamic method calls?

    by Chris Altman /

    Your message is awaiting moderation. Thank you for participating in the discussion.

    There are some times when I'm not sure if I am going to call .Add() or .Subtract() on an object until runtime. Rather than building a dynamic method that is wrapped in an switch statement to call the appropriate object method. I'd still like to be able to, for example, call Invoke("Add", 10, 20).

    Hopefully that makes sense.
