If we wish to write a program for controlling a device for instance for a mobile phone we have a lot of items to pay attention to: We have a to provide a method to enter the number, we need to update the display, for a subsequent correction, the numbers have to be stored, it expects a key tone when inserting, the phone number has to be sent to the provider etc.

The programm can become complex. If we programm in an object-oriented-language, we have the ability to divide these tasks to different classes. You find datails in the agendas of the seminars like that: .NET Seminare in C#,VB.NET(German).

So what is a class ?
A class holds data and methods. A class is a blueprint and provides data and associated methods. We define a class for the keyboard, the display, the provider, etc.. These various classes perform only their own tasks. The classes only contain data, they require for their task and the methods to change the data. The object-oriented-language provides us with mechanisms to avoid access of data from one class to another class.

Through inheritance a class is reused. All data and methods are inherited from the base class. Program errors are to be searched predominantly in the derived classes if the base classes are well tested. Those technics are used in the folowing seminars: Windows Forms mit C#,VB.NET(German).

You are able to test the program in a shorter time. Only the modified classes have to be verified if you change the program. Of course you should check the interaction of the classes. If we want to realize today’s complicated programs in a reasonable time we are well advised to use object-oriented-programs. Troubleshooting and maintaining of the program requires less effort and is less expensive. An excellent way to improve your company’s C-Sharp skills, is by booking a Dotnet-Seminar(German).
