Question

I have

public delegate void DocumentCompleteEventHandler(object pDisp, ref object URL)

Can i use lambda expression such as :

ie.DocumentComplete += (o, e) => {  };

It expression doesn’t work. How should i change it for using in code? Is it possible?

Answer 1

Have you tried:

ie.DocumentComplete += (object o, ref object e) => {};

Sometimes the compiler can’t figure out things through pure inference and you need to specify the labmda argument types (and modifiers.) Note that it’s an all-or-nothing thing: you must given types for all arguments or not at all.

p.s. I’m waiting for a certain Mr. Skeet to hop in here and paste in an essay to steal all of my points.
