Use variables and the Length property to show how long text is

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 frmWordLength.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:

The idea is to attach code to the two buttons so that they do what they say they will!

Attach code to the button on the left so that it creates two variables:

Variable	Type	Will hold
phrase	string	The text typed into the box
phraseLength	int	The number of characters in the phrase

Get the button to display two messages in succession. The first message should confirm what text you typed in:

A simple message summarising what you typed in.

The second message should say how many letters this message contains:

The number of letters in the message your user typed in.

Use Length to show the length of your text. Note that this is a property, not a method, and so doesn't need any brackets after it.

Use Replace to replace every space in the phrase with an empty string ("") to get the second button to work:

Clicking on the second button should display this message for the text typed in here.

You get bonus points for using the Trim() method to remove any leading or trailing spaces from your text before finding out how long it is!

Close down any files that you have open. The preceding sentence had 40 characters in, if you're interested!

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