Use a list to add, remove, count and display the Beatles

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.

Before you can do this exercise, you'll need to download and unzip this file .

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 frmTheBeatles.cs in the above folder.

Make this the default form in Program.cs. When you run your application, you should see a form like this:

The Beatles form

The only thing remaining is to get the buttons to do what they say they do!

Create a private variable in the form's code-behind to hold a list of objects of type string.

Now attach code to the buttons so that when you click on them from top to bottom you get these messages:

The first and last messages

The middle two messages are not shown here.

When you've got this working, write out 50 lines:

"I must not use arrays again just because I know them better from previous programming languages, when lists are so easy."

Close down any files you have open.

You can unzip this file to see the answers to this exercise, although please remember this is for your personal use only.
