Project a star sign class into an enumerable string list using LINQ

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 .

Add the forms and files in the above folder into your current project, and make the form frmStarSigns.cs the default form in Program.cs.

When you run your project and click on the button, you should see this:

Star signs list

When you click on the button you see the text shown; the aim of this exercise is to get the button to list out all of the summer star signs too.

The code attached to the button creates a list of objects of type StarSign. Your task is to change this to use a LINQ query expression to iterate over the items in this list, transforming the results into an enumerable collection of strings giving the names of the summer star signs.

Summer is defined as when the start month of the star sign is in May, June, July or August.

When you run your revised code, you should see something like this:

Summer star signs form

What you should see now when you click on the button.

End your application. If you have spare time, you could fill in the name of the star sign that everyone forgets!

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