How do closures work behind the scenes? (C#)

Question

I feel I have a pretty decent understanding of closures, how to use them, and when they can be useful. But what I don\'t understand is how they actually work behind the sce

Answer 1

Your third guess is correct. The compiler will generate code like this:

private class Locals
{
  public int count;
  public void Anonymous()
  {
    this.count++;
  }
}

public Action Counter()
{
  Locals locals = new Locals();
  locals.count = 0;
  Action counter = new Action(locals.Anonymous);
  return counter;
}

Make sense?

Also, you asked for comparisons. VB and JScript both create closures in pretty much the same way.
