的MainMenu /文本菜单已过时，您应该使用菜单条的类来代替。

修改

  notifyContextMenu =新System.Windows.Forms.ContextMenu（）;
notifyContextMenu.MenuItems.Add（退出）;
 

到

  notifyContextMenu =新System.Windows.Forms.ContextMenuStrip（）;
VAR exitMenuItem = notifyContextMenu.Items.Add（退出）;
exitMenuItem.Image = ...;

最后附上上下文菜单条通知图标，

  notifyIcon.ContextMenuStrip = notifyContextMenu;
 

I tried to add an icon to one of my context menu items, but I couldn't do it. Can anybody help me?

Here's the code I've written:

 private System.Windows.Forms.ContextMenu notifyContextMenu;
 private void foo() {
            if (notifyIcon == null) {
                notifyIcon = new System.Windows.Forms.NotifyIcon();   
            }

           if (notifyContextMenu == null) {
               notifyContextMenu = new System.Windows.Forms.ContextMenu();
               notifyContextMenu.MenuItems.Add("Exit");
               // How do I add an icon to this context menu item?
             }
            notifyIcon.ContextMenu =  notifyContextMenu;
          }
     }

MainMenu/ContextMenu are obsolete, you should use the menu strip classes instead.

Change

notifyContextMenu = new System.Windows.Forms.ContextMenu();
notifyContextMenu.MenuItems.Add("Exit");

to

notifyContextMenu = new System.Windows.Forms.ContextMenuStrip();
var exitMenuItem = notifyContextMenu.Items.Add("Exit");
exitMenuItem.Image = ...;

Finally attach the context menu strip to notify icon,

notifyIcon.ContextMenuStrip = notifyContextMenu;
