獲取唯一值

Question

我有一個字符串像這樣的列表：

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

我需要得到一個新的字符串列表，只有不同的值：

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

任何人都有一個快速的方法來做到這一點？

Answer 1

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

Answer 2

您可以使用DISTINCT方法：

List<string> distinctList = dupeList.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(); 

或者你可以使用一個HashSet

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