Visual C# | Inheritance exercise | Use inheritance to apply to appear on BGT
This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.
You can learn how to do this exercise on the relevant Wise Owl classroom training course (sadly for the moment only in the UK).

You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
If you haven't already got one, create a Windows Forms project (using Visual C#, obviously) called wiseowl. Right-click on your project in Solution Explorer to add an existing item, and choose the file frmReality.cs in the above folder.
Make this the default form in Program.cs. Run your application and click on the button in the form which appears, to get:
The code creates 3 applications to appear on reality TV shows, using the RealityApplication class at the bottom of the form's code.
You now want to apply to Britain's Got Talent, but to do this you'll have to say what your applicant's talent is so you can display this in the message box:
The BGT application has to include the name of the talent your applicant will exhibit (in this case, dancing).
Add a class called BGTApplication which inherits from the RealityApplication class, but includes an extra property called Talent, eventually allowing you to add this code:
// add a Britain's Got Talent application
var app4 = new BGTApplication {
ApplicantName = "My cat",
ShowName = "BGT",
Talent = "Dancing" };
You'll need to override the base class's Description property to do this! When you've got everything working, you might like to consider what your talent would be ...
