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);
}
