This interface is used in conjunction with the Array.Sort and Array.BinarySearch methods. It provides a way to customize the sort order of a collection. See the Compare method for notes on parameters and return value.

The default implementation of this interface is the Comparer class. For the generic version of this interface, see System.Collections.Generic.IComparer(T).

The following code example demonstrates the use of the IComparer interface to sort an ArrayList object. In this example, the IComparer interface is implemented using the CaseInsensitiveComparer class to reverse the order of the contents of the ArrayList.

No code example is currently available or this language may not be supported.
