How do you get the index of the current iteration of a foreach loop?

Question

Is there some rare language construct I haven\'t encountered (like the few I\'ve learned recently, some on Stack Overflow) in C# to get a value representing the current iter

Answer 1

For interest, Phil Haack just wrote an example of this in the context of a Razor Templated Delegate (http://haacked.com/archive/2011/04/14/a-better-razor-foreach-loop.aspx)

Effectively he writes an extension method which wraps the iteration in an "IteratedItem" class (see below) allowing access to the index as well as the element during iteration.

public class IndexedItem {
  public IndexedItem(int index, TModel item) {
    Index = index;
    Item = item;
  }

  public int Index { get; private set; }
  public TModel Item { get; private set; }
}

However, while this would be fine in a non-Razor environment if you are doing a single operation (i.e. one that could be provided as a lambda) it's not going to be a solid replacement of the for/foreach syntax in non-Razor contexts.
