A MainMenu is the Menu strip across the top of a Form . You can bind it to a particular form by using the Form.Menu property. There is an additional typed CloneMenu() method, which allows you to copy the menu structure for reuse elsewhere. See Menu for more information on menu functionality. public class MainMenu : Menu { // Public Constructors public MainMenu (); public MainMenu (MenuItem[ ] items ); // Public Instance Properties public virtual RightToLeft RightToLeft {set; get; } // Public Instance Methods public virtual MainMenu CloneMenu (); public Form GetForm (); public override string ToString (); // overrides Menu // Protected Instance Methods protected override IntPtr CreateMenuHandle (); // overrides Menu protected override void Dispose (bool disposing ); // overrides Menu } HierarchySystem.Object System.MarshalByRefObject System.ComponentModel.Component(System.ComponentModel.IComponen, System.IDisposable) Menu MainMenu Returned ByForm.{Menu , MergedMenu} , Menu.GetMainMenu() , PrintPreviewDialog.Menu Passed ToForm.Menu , PrintPreviewDialog.Menu |
