Starting with the .NET Framework 2.0, this method uses the collection’s objects’ Equals and CompareTo methods on item to determine whether item exists. In the earlier versions of the .NET Framework, this determination was made by using the Equals and CompareTo methods of the item parameter on the objects in the collection.

The following example demonstrates the implementation of the IList interface to create a simple, fixed-size list. This code example is part of a larger example provided for the IList interface.
