Hour 11. Creating and Calling Methods

You've now spent about 11 hours building the basic skills necessary to navigate C# and to create an application interface. Creating a good interface is extremely important, but it's only one step toward creating a Windows program. After you've created the basic interface of an application, you need to enable the program to do something. The program may perform an action all on its own, or it may perform actions based on a user interacting with the interface—either way, to make your application perform tasks, you write C# code. In this hour, you'll learn how to create sets of code (called classes), and how to create and call isolated code routines (called methods).

The highlights of this hour include the following:

• Creating static class members
• Creating methods
• Calling methods
• Exiting methods
• Passing parameters
• Avoiding recursive methods
• Working with tasks
