Get unique values from a List of strings

Question

I have a List of strings like this:

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

And I need get a new list of strings with only the different values:

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

Anyone have a quick way to do this?

Answer 1

You can use the Distinct method:

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();

Or you could use a HashSet

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