从字符串列表中获取唯一值

Question

我有一个像这样的字符串列表：

{"100", "101, "101", "102, "103, "103", "104", "104", "105"}

我需要获得一个只有不同值的新字符串列表：

{"100","101","102","103","104","105"}

任何人都有快速的方法吗？

Answer 1

您可以使用Distinct方法：

List<string> distinctList = dupeList.Distinct().ToList();

Answer 2

List<String> strings = new List<string>() { "100", "101", "101", "102", "103", "103", "104", "104", "105" };
var distinctStrings = strings.Distinct().ToList(); 

Answer 3

List<string> dupes = new List<string>(){"100", "101, "101", "102, "103, "103", "104", "104", "105"};
List<string> no_dupes = dupes.Distinct().ToList();

或者您可以使用HashSet

var noDupes = new HashSet<string>(dupes).ToList();
