list with distinct and StringComparison.OrdinalIgnoreCase

Question

I have list, how can I get distinct values?

IList<string> words = new List<string> { "A", "b", "a" };
var distinctWords = words.Distinct(StringComparison.OrdinalIgnoreCase);

this gives me error: Distinct has some invalid arguments.

Answer 1

You need: StringComparer.OrdinalIgnoreCase not StringComparison.OrdinalIgnoreCase

IList<string> words = new List<string> { "A", "b", "a" };
var distinctWords = words.Distinct(StringComparer.OrdinalIgnoreCase);
