Find the longest text in a combo box by looping over its items

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 .

To avoid having to draw the form needed for this exercise, right-click on the name of your project in Solution Explorer then choose Add --> Existing Item... (you can also press SHIFT + ALT + A to do the same thing).

Choose only the file called frmHobsonsChoice.cs in the above folder to import it into your project, then edit Program.cs to make this the default form. When you run your application, you should now see this:

List of date choices

But will you be able to recognise him?

Attach code to the button so that when you click on it you see the longest name in a message box (you can get this by looping over all of the items to find the longest):

The longest name

There was a clue in the title of the folder containing the form ...

You may find the following lines of code useful to refer to or crib!

// read the combo box items into an array

string longestName = "";

foreach (string possibleDate in cmbDate.Items)

When you've got everything working, close down the form.

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