c# - How do i exit a List<string>.ForEach loop when using an anonymous delegate?

Question

In a normal loop you can break out of a loop using break. Can the same be done using an anonymous delegate?

Example inputString and result are both declared outside the delegate.

blackList.ForEach(new Action<string>(
    delegate(string item)
    {
        if(inputString.Contains(item)==true)
        {
            result = true;
            // I want to break here
        }
    }
));

Edit: Thanks for the replies, I'm actually reading your book at the minute John :) Just for the record i hit this issue and switched back to a normal foreach loop but I posted this question to see if i missed something.

Answer 1

As others have posted, you can't exit the loop in ForEach.

Are you able to use LINQ? If so, you could easily combine TakeWhile and a custom ForEach extension method (which just about every project seems to have these days).

In your example, however, List<T>.FindIndex would be the best alternative - but if you're not actually doing that, please post an example of what you really want to do.
