This course introduces properties and indexers•elements of Microsoft Visual C#®•that enable you to encapsulate data and expose data appropriately and efficiently. You will gain an understanding of how to implement operators for your types by using overloading. This knowledge will help you to develop applications with more efficient and secure entities. The course describes how you can decouple methods and handle events; this knowledge will help you to call methods determined dynamically at runtime or to call code that other developers have written for applications that consume your type. It will also help you to use events to inform consuming applications of a change or notable occurrence in a type.
