MenuItem addDevice = new MenuItem("Add Device"); 
addDevice.MenuItems.Add(new MenuItem("Add More .."));

您可以添加此

var someMenu= new MenuItem("Foo"); 
someMenu.MenuItems.Add(new MenuItem("foo "));

答

format不为我工作。我被迫使用：

// People often exclude the applicable "using" statements--so samples don't work! 
using System.Web.UI.WebControls; 

// Create the MAIN menu item 
MenuItem mnuMenuItem = new MenuItem();   

// Create the SUB menu item 
MenuItem mnuSubMenuItem = new MenuItem();  

// Create the SUB menu item, "under" the MAIN menu item! 
mnuMenuItem.ChildItems.Add(mnuSubMenuItem);

答

MenuItem newMenuItem1 = new MenuItem("Employee Master"); 
      MenuItem mnuSubMenuItem = new MenuItem(); 
      newMenuItem1.ChildItems.Add(mnuSubMenuItem); 
      mnuSubMenuItem.Text = "Add User..."; 
      mnuSubMenuItem.NavigateUrl = "ADDURL.aspx"; 

      MenuItem mnuSubMenuItem1 = new MenuItem(); 
      newMenuItem1.ChildItems.Add(mnuSubMenuItem1); 
      mnuSubMenuItem1.Text = "Edit User..."; 
      mnuSubMenuItem1.NavigateUrl = "EDITURL.aspx"; 
      this.MenuMaster.Items.Add(newMenuItem1);
