In C#, what is the fastest way to remove one collection from another Collection?

I have two collections that are both:

 List<MyObject>
  1. fullCollection
  2. oldCollection

I want to find out which objects are in the full list but not the other list. What is the fastest ways to do something like this:

var inOneButNotTheOther = 
    fullCollection.Remove(oldCollection, new MyObjectComparer());
