.NET Tip: Sort an ArrayList Using a Custom Comparer Class

(Jay Miller) The Sort() method of the ArrayList class allows you to provide your own comparer. When you provide a comparison object, your Compare() method will be used to compare objects in the ArrayList when sorting. This flexibility allows you to sort by any means that you choose. This example will sort an ArrayList that contains objects of different types. The Compare() method sorts them based on the name of the data type of the object. First, take a look at the DataTypeComparer class that implements the IComparer interface and defines a Compare() method that does a comparison based on the names of the data types of two objects.
