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
