list with distinct和StringComparison.OrdinalIgnoreCase

Question

我有清单,我怎样才能获得不同的价值观？

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

这给了我错误: Distinct有一些无效的参数.

Answer 1

你需要:StringComparer.OrdinalIgnoreCase不是StringComparison.OrdinalIgnoreCase

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