无语...怎么就不行,关于ToolStripMenuItem

Question

在Form已经建了个contextMenuStrip1,并加了个item  MenuItemCopySelection
经调试,下面根本就不运行,不知道为什么??....richTextBox1我是放在一个tabControl里....
        private void MenuItemCopySelection_Click(object sender, EventArgs e)
        {
            if (richTextBox1.SelectedText.Equals(""))
                return;
            else
            {
            Clipboard.SetDataObject(richTextBox1.SelectedText, true); 
            }
        }

            MenuItem MenuItemCopySelection = new MenuItem("Copy Selection");
            MenuItemCopySelection.Click += new EventHandler(MenuItemCopySelection_Click);
            richTextBox1.ContextMenu = new ContextMenu(new MenuItem[] { MenuItemCopySelection });
        }        private void MenuItemCopySelection_Click(object sender, EventArgs e)
