c# Check if all strings in list are the same [duplicate]

Answer 1

var hasIdenticalItems = list.Count() <= 1 || list.Distinct().Count() == 1;

Answer 2

var allAreSame = list.All(x => x == list.First());

Answer 3

var allAreSame = list.Distinct().Count() == 1;

or a little more optimal

var allAreSame = list.Count == 0 || list.All(x => x == list[0]);

Answer 4

How about this:

    string[] s = { "same", "same", "same" };
    if (s.Where(x => x == s[0]).Count() == s.Length)
    {
        return true;
    }
