Visual C# | Advanced LINQ exercise | Iterate over star signs using LINQ, projecting into text
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.
The answer to the exercise will be included and explained if you attend the course listed below!
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.
Add the files in the folder above to your project, and change the default form to frmStarSigns. When you run your project and click on the button, you should see this:
You'll change this to list out all of the summer star signs.
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, projecting the results into an enumerable collection of strings giving the names of the summer star signs. Your query expression should begin something like this:
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:
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!
