What is the difference between Contains and Any in LINQ?

by

Contains takes an object, Any takes a predicate.

You use Contains like this:

listOFInts.Contains(1);

and Any like this:

listOfInts.Any(i => i == 1);
listOfInts.Any(i => i % 2 == 0); // Check if any element is an Even Number

So if you want to check for a specific condition, use Any. If you want to check for the existence of an element, use Contains.

MSDN for Contains, Any
