C# PLEASE

Write a switch statement that tests the value of my_var and performs the following actions:

• if my_var is 1, the message "Option 1 was selected." will be display.
• if my_var is 2, the message "Option 2 was selected." will be display.
• if my_var is 3, the message "Option 3 was selected." will be display.
• other values will result in the message "Invalid option" will be displayed.

Assume that my_var was declared and initialize to a value already. You can also assume console namespace was declared too.
