You need to pass a IComparer object or Comparison delegate to the Sort function.

Here is a sample code from C# 2.0

   Array.Sort(array,delegate(string a, string b)
    {
        return b.CompareTo(a);
    });

EDIT: missed the array bit.

if you use a different comparitor that is the reverse of the standard that would do it.

Alternatively sort it normally and then reverse it...

Provide an appropriate element comparer. What C# version do you use? 3 lets you do this:

Array.Sort(myarray, (a, b) => b.CompareTo(a));
