Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

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 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 buttons

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:

 Message after first button Message after 4th button
After the first button After the 4th button

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.
