How to add a separator to a WinForms ContextMenu?

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?

Horizontal separators are cool, but what if you want a vertical separator instead?

Well, worry ye not - you can have one!

Set BarBreak property to true on the MenuItem which should be the first one after the seperator:

var item = new MenuItem(text: "Settings", onClick: SomeFunction) { BarBreak = true };

enter image description here

To add the item to a MenuItems collection: yourContextMenu.MenuItems.Add(item).

ContextMenu has a constructor which receives an array of MenuItem objects. Needless to say, you can't add a string to that array. You can however get a seperator by adding a new MenuItem("-"):

    var contextMenu = new ContextMenu(new[]
    {
        timerMenuItem,
        keypressMenuItem,
        new MenuItem("-"), // Seperator
        new MenuItem(text: "Exit", onClick: (sender, args) => Application.Exit())
    });

Perhaps in later versions of Visual Studio they made this simpler. I'm using VS 2012. You can add a separator via the forms designer. 1) Select/Create a MenuStrip. 2) On "Type Here", right mouse. 3) Select "Insert". 4) Select "Separator". 5) Drag the new separator to the text you want it to be above. Done.

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.

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());

I believe it's just a dash:

ContextMenu.MenuItems.Add("-");
