动态添加ContextMenuStrip项（ToolStripItem）

       //绑定菜单
        private void BindMenu(DataTable dt)

        {

            foreach (DataRow row in dt.Rows)

            {

                ToolStripItem item = new ToolStripMenuItem();

                item.Name = row[0].ToString();

                item.Text = row[1].ToString();

                item.Click += new EventHandler(contextMenuStrip1_ItemClick);

                contextMenuStrip1.Items.Add(item);

                //contextMenuStrip1.Items.Add(row[1].ToString(), null, contextMenuStrip1_ItemClick);

            }

        }

        private void contextMenuStrip1_ItemClick(object sender, EventArgs e)

        {

            ToolStripItem item = (ToolStripItem)sender;            

            MessageBox.Show(item.Name);

        }
