如果你想获得一个菜单项，从处理程序的位置，你可以继续工作了每一位业主的项目，并找到它的位置完整的职位列表：

// Get a reference to the current item as a tool strip menu item 
ToolStripMenuItem self = (ToolStripMenuItem)sender; 

// Build a list of positions 
List<int> position = new List<int>(); 
ToolStripMenuItem cur = self; 
// Keep looping until we don't find a parent 
while (cur != null) 
{ 
    if (cur.OwnerItem is ToolStripMenuItem) 
    { 
     // The owner is a menu item, add it's position to our list 
     ToolStripMenuItem parent = ((ToolStripMenuItem)cur.OwnerItem); 
     position.Insert(0, parent.DropDownItems.IndexOf(cur)); 
     // And now work on the owner 
     cur = parent; 
    } 
    else 
    { 
     // The owner isn't a menu item, so break out of our loop 
     cur = null; 
    } 
} 

// And as a demo, just show the positions: 
MessageBox.Show("You clicked on item at " + 
    string.Join(",", position.Select(x => x.ToString()).ToArray()));
