Windows forms support two relevant classes for menu building: MainMenu and MenuItem. A menu item in Windows forms needs three variables:

• The top menu bar
• The menu column (File in our case)
• The menu item (Save in our case)

Let's call these variables menuMain, menuFile, and menuSave. We define them as follows:

  var menuMain : System.Windows.Forms.MainMenu;
  var menuFile : System.Windows.Forms.MenuItem; 
  var menuSave : System.Windows.Forms.MenuItem;
