Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public int Count { get; }

Property Value

Type: System.Int32

The number of MenuItem objects in the collection.

The Count property holds the number of MenuItem objects assigned to the collection. You can use the Count property value as the upper bounds of a loop to iterate through a collection. Keep in mind, the index value of a collection is a zero-based index, so you must subtract one from the looping variable. If you do not account for this, you will exceed the upper bounds of the collection and throw an exception.

The following code example shows how to create a main menu, myMainMenu, with one MenuItem, File, that has three submenu items: New, Open, and Exit. Using the Count property, you count the number of objects in the File menu and display this number in a message box. This example requires that you have already created a Form named Form1.

public void InitializeMyMenu()
{
	// Create the MainMenu object.
	MainMenu myMainMenu = new MainMenu();

	// Create the MenuItem objects.
	MenuItem fileMenu = new MenuItem("&File");
	MenuItem newFile = new MenuItem("&New");
	MenuItem openFile = new MenuItem("&Open");
	MenuItem exitProgram = new MenuItem("E&xit");

	// Add the File menu item to myMainMenu.
	myMainMenu.MenuItems.Add(fileMenu);

	// Add three submenus to the File menu.
	fileMenu.MenuItems.Add(newFile);
	fileMenu.MenuItems.Add(openFile);
	fileMenu.MenuItems.Add(exitProgram);

	// Assign myMainMenu to the form.
	this.Menu = myMainMenu;

	// Count the number of objects in the File menu and display the result.
	string objectNumber = fileMenu.MenuItems.Count.ToString();
	MessageBox.Show("Number of objects in the File menu = " + objectNumber);
}
