c# - 如何在列表中查找重复项并按出现次数对它们进行排序

Question

有没有一种简单的方法可以在列表中找到重复项，然后按出现次数对它们进行排序？此外，应删除重复项。

例如。你有一个List<String>像这样:

List<String> = new List<String>{"6","1","2","2","4","6","5","1","6","6","2"};

问题是，如何将这个列表转换为 -> "6"、"1"、"2"、"4"、"5"？

Answer 1

使用 Linq.Distinct()

List<String> list = new List<String>{"6","1","2","2","4","6","5","1","6","6","2"};
list = list.Distinct().ToList();
