Remove elements from one List that are found in another

Question

I have two lists

 List list1 = new List();
 List list2 = new List();

I want remove all elements from li

Answer 1

If you want to remove a list of objects (list2) from another list (list1) use:

list1 = list1.Except(list2).ToList()

Remember to use ToList() to convert IEnumerable to List.
