fastest way to see if IEnumerable<T> contains item based on criteria

Question

Sort of a Linq beginners question, but is there a simple built-in way to optimize this:

bool containsItemWithValue42 = items.Where(i => i.Value == 42).Count() > 0;

I would like Linq to stop iterating as soon as it found a match.

Answer 1

The Any method does exactly that:

bool containsItemWithValue42 = items.Any(i => i.Value == 42);
