fastest way to see if IEnumerable<T> contains item based on criteria
Sort of a Linq beginners question, but is there a simple built-in way to optimize this:
bool cont开发者_如何转开发ainsItemWithValue42 = items.Where(i => i.Value == 42).Count() > 0;
I would like Linq to stop iterating as soon as it found a match.
The Any
method does exactly that:
bool containsItemWithValue42 = items.Any(i => i.Value == 42);
