C# Assert.AreEqual

I am trying to test my code but I am getting an error and I shouldn't.  Code is below.

List<string> expected = new List<string>();
expected.Add("hello");

List<string> result = new List<string>();
result.Add("hello");

Assert.AreEqual(expected, result);

Select allOpen in new window

I'm receiving the following error:  

Assert.AreEqual failed.
Expected:<System.Collections.Generic.List`1[System.String]>.
Actual:<System.Collections.Generic.List`1[System.String]>.
