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.

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 frmOldies.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:

Oldies dating agency form

When someone types in their name/age and clicks on the button, they should see confirmation of their name, age and status (read on for what this means!).


Create the following properties for your application form for this senior citizens' dating agency (motto: It's never too late to date!):

Property Type Contains
PersonName Read-only The name of the applicant
Age Read-only The age of the applicant
Status Read-only Senior citizen if over 65; adult if over 18; child otherwise
IfEligible Read-only Whether this person can join (they must be over 65 to do so)

If you've written these properties correctly, you should be able to attach the following code to the Show details button to show a summary of this applicant's status in the output or immediate window:

// print out details of this person (must reference

// System.Diagnostics namespace at top of code)

Debug.WriteLine("PROPERTY VALUES");

Debug.WriteLine(" ");


Debug.WriteLine("Name = " + personName);

Debug.WriteLine("Age = " + age.ToString());

Debug.WriteLine("Status = " + status);

Debug.WriteLine((IfEligible ? "Eligible" : "Not eligibile"));


Here's what your output should look like when you enter a couple of people's details:

Debug output from application form

Here we've entered the details of two people at the opposite ends of life. Which one do you suppose is the more content?


Close down your application and any open forms.
