[Mono-devel-list] [PATCH] parameters validation testing in System.Collections.Specialized.ListDictionary.CopyTo()

[Alon Gazit]

Hello,

The method System.Collections.Specialized.ListDictionary.CopyTo(Array
array, int index) should perform the following validation tests:
1. if the array parameter is null , the method should throw
ArgumentNullException.
2. if the index parameter's value is less than 0 ,  the method should
throw ArgumentOutOfRangeException

Steps to reproduce the problems:
1. create a new instance of ListDictionary
2. call the method CopyTo(Array array, int index) , with null and 0 as
parameters .
3. call the method CopyTo(Array array, int index) , with a one
dimensional array instance and -1 as parameters .

Actual Results:
the method does nothing.

Expected Results:
the method throws the relevant exception.

Enclosed is a small test case and a patch.

Thanks a lot,

Alon Gazit
