ArrayList.Sort method in C#

Today I first used the sort method of ArrayList in C#.
 In order to sort the data under my business logic I designed a class inherit the IComparer interface,
then I realized the method -- Compare of the interface,in which I coded some logic to
compare two objects and return a value indication whether one is less than,equal to
or greater than the other.
There is a simple sample here

ArrayList myAL = new ArrayList();
            myAL.Add("The");
            myAL.Add("QUICK");
            myAL.Add("BROWN");
            IComparer myComparer = new myCompare();
            myAL.Sort(0, 3, myComparer);


    public class myCompare : IComparer
    {
        int IComparer.Compare(Object x, Object y)
        {
            return ((new CaseInsensitiveComparer()).Compare(y, x));
        }
    }

I think the sort way of ArrayList designed in C# is great , we can sort the elements in any way we want
