Remove content of list from another list

How do I remove the content of one list from anot开发者_开发问答her list?

list1.RemoveAll(i => list2.Contains(i));

List<object> result = anotherlist.Except(list).ToList();

Here is a short addition and advise to James post.

If you are using List<T> and the myOtherList contains many items you should convert it to a Hashset<T> var set = new Hashset(myOtherList), so his solution should run much faster.
