If we wish to write a program for controlling a device for instance for a mobile phone we are quickly confronted with many different tasks: We have a to supply a method to enter the number, we need to update the display, the numbers inserted should be persisted in case of a correction, it expects a key tone when inserting, the phone number has to be sent to the provider etc.

The programm can become complicated. If we can use an object-oriented-language, we can produce a class for each task. You find datails in the agendas of the seminars like that: Inhouse Schulung in C#,VB.NET(German).

So what is a class ?
A class contains data and methods. You can think of a class as a blueprint specifying data and methods. We specify a class for the keyboard, the display, the provider, etc.. These classes are concentrating only on their own task. The methods of each class can only change their own data. It is not possible to change data from outside the class.

Through inheritance a class is reused. All data and methods are inherited from the base class. If the base classes are well examined, program faults need to be find only in the derived new classes. 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 tested if you modify the program. Changes are therefore much easier to carry out. We have 2000 classes and more in large programs. The complexity of the tasks is divided into many small, manageable classes. Troubleshooting and maintaining of the program needs less effort and is less expensive. A very good way to improve your teams C-Sharp skills, is by booking a Firmenseminar(German) .
