How to add a separator to a WinForms ContextMenu?

Question

Inside my control, I have:

ContextMenu = new ContextMenu();
ContextMenu.MenuItems.Add(new MenuItem("&Add Item", onAddSpeaker));
ContextMenu.MenuItems.Add(new MenuItem("&Edit Item", onEditSpeaker));
ContextMenu.MenuItems.Add(new MenuItem("&Delete Item", onDeleteSpeaker));
ContextMenu.MenuItems.Add( ??? );
ContextMenu.MenuItems.Add(new MenuItem("Cancel"));

How to add a separation line to this ContextMenu?

Answer 1

I believe it's just a dash:

ContextMenu.MenuItems.Add("-");

Answer 2

This works just as well as the dash, and i suspect the Winforms will translate the dash to a ToolStripSeparator. I for one think this solution is more obvious for anyone who has to maintain the code.

yourContextMenu.Items.Add(new ToolStripSeparator());

Answer 3

In WPF:

ContextMenu.MenuItems.Add(new Separator());

Answer 4

If you are using the Designer, place a single hyphen "-" as text the same way you would name your menu items. After hitting enter, the separator will be created.
