Title: Default parameters - Asp.net Course with Visual Studio 2010 - Lesson 3

Duration:  15 minutes

Summary: In this video, we continue our example that explains the new C# 4.0 features. We continue the Exam class and add new method to it. This method will illustrate another feature added to C# 4.0 - default parameters. We will default the last parameter (name in this case). Now when the user calls this method, he/she does not need to provide a value for the name. In the Main method, we create an instance of the Exam class, and make calls to the Register methods. In some calls we pass all the parameters. In other calls, we leave out the name parameter and let the method use the default. In yet another call, we use the named parameters: in this case, we pass the parameter by name, and ignoring the order. Finally, we see another feature of Visual Studio 2010: by right clicking on a method and viewing the call hierarchy. In this way, we call see the calls made to this method and the calls made from this method.

Methodology of the development of example: Good coding standard and simplified design to illustrate the key points.
