Delegate / Action variable capture / value capture:

Dynamically create button listeners with parameter passing.

You’re almost there… the above is likely perfect EXCEPT that C# does “variable capture” instead of value capture. This means that your listeners will ALL be created and use the final value of i, not an ever-increasing 0, 1, 2, 3 etc which is what you want. SO… what you want to do is make a local variable inside the for() loop block: int i2 = i; // capture for delegate And now use i2 anywhere in the delegate. Each time through the loop that is a brand-new instance of the local variable, eac…

Well, closures are a topic on their own. The wikipedia article may be a bit overkill. The important part is essentially about the “capturing”. There are two ways to look at it, from a purely functional point of view and from the technical point of view. The functional point of view is simply: A closure is an anonymous inline declared method that has access to local variables which are normally not accessable from inside the method. So the method simply can “hold onto” the local variables. It’s …
