Why doesn't Any() work on a c# null object

Question

When calling Any() on a null object, it throws an ArgumentNullException in C#. If the object is null, there definitely aren\'t \'any\', and it should probably return false.

Answer 1

Any() is an extension method, so this is actually passed as the first argument to the method. In this situation, it's understandable for it to throw ArgumentNullException is this is null.

You can perform the check yourself beforehand:

bool hasAny = yourData == null ? false : yourData.Any(yourPredicate);
