[Mono-devel-list] [PATCH] null argument testing in System.Collections.Specialized.ListDictionary.Remove()

The method System.Collections.Specialized.ListDictionary.Remove(object
key) should throw ArgumentNullException, when the parameter is null.

Steps to reproduce the problem:
1. Create a new instance of ListDictionary
2. call the method Remove(object key) , with null as parameter.

Actual Results:
the method throws NullReferenceException.

Expected Results:
the method throws ArgumentNullException.

Enclosed is a small test case and a patch.

Thanks a lot,

Alon Gazit
