c# - Test if all values in a list are unique

Question

I have a small list of bytes and I want to test that they're all different values. For instance, I have this:

List<byte> theList = new List<byte> { 1,4,3,6,1 };

What's the best way to check if all values are distinct or not?

Answer 1

bool isUnique = theList.Distinct().Count() == theList.Count();
