Handling and Raising Events

Events in the .NET Framework are based on the delegate model. (Those familiar with design patterns in object-oriented programming will notice the observer design pattern.) This section contains topics that describe the delegate model, show how to consume events in applications, and describe how to raise events from your class.

For details about the event syntax in a specific programming language, see the documentation for that language.
