Remove elements from one List that are found in another

Question

I have two lists

 List list2 = new List();

I want remove all elements from li

Answer 1

Description

I think you mean the generic type List. You can use Linq to do this

Sample

List l = new List();
List l2 = new List();

l.Add("one");
l.Add("two");
l.Add("three");

l2.Add("one");
l2.Add("two");
l2.Add("three");
l2.Add("four");

l2.RemoveAll(x => l.Contains(x));
