Generics Sample (C#)

This sample shows how to create a custom generic list class that has a single type parameter, and how to implement IEnumerable<T> to enable foreach iteration over the contents of the list. The sample also shows how client code creates an instance of the class by specifying a type argument, and how constraints on the type parameter enable additional operations to be performed on the type arguments.

For an example of a generic collection class that implements an iterator block, see How to: Create an Iterator Block for a Generic List (C# Programming Guide).

To build and run the Generics sample within Visual Studio

  • On the Debug menu, click Start Without Debugging.

To build and run the Generics sample from a command prompt

  • Type the following at the command prompt:

    csc generics.cs


This sample is provided for demonstration and is not intended for use in production code without modification. For production quality code, we strongly recommend that you use the collection classes in the System.Collections.Generic namespace whenever possible.
