C# winform 用contextmenustrip 动态生成菜单

示例代码：

protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);

//添加菜单一
ToolStripMenuItem subItem;
subItem = AddContextMenu("新闻", contextMenuStrip1.Items, null);
//添加子菜单
AddContextMenu("今日要闻", subItem.DropDownItems, new EventHandler(MenuClicked));
AddContextMenu("今日关注", subItem.DropDownItems, new EventHandler(MenuClicked));

//添加菜单二
subItem = AddContextMenu("笑话", contextMenuStrip1.Items, null);
//添加子菜单
AddContextMenu("现代笑话", subItem.DropDownItems, new EventHandler(MenuClicked));
AddContextMenu("古代笑话", subItem.DropDownItems, new EventHandler(MenuClicked));
}

///

/// 添加子菜单
///

/// 要显示的文字，如果为 - 则显示为分割线
/// 要添加到的子菜单集合
/// 点击时触发的事件
/// 生成的子菜单，如果为分隔条则返回null

ToolStripMenuItem AddContextMenu(string text, ToolStripItemCollection cms, EventHandler callback)
{
if (text == "-")
{
ToolStripSeparator tsp = new ToolStripSeparator();
cms.Add(tsp);

return null;
}
else if (!string.IsNullOrEmpty(text))
{
ToolStripMenuItem tsmi = new ToolStripMenuItem(text);
if (callback != null) tsmi.Click += callback;
cms.Add(tsmi);

return tsmi;
}

return null;
}

void MenuClicked(object sender, EventArgs e)
{
MessageBox.Show("You Clicked Menu Item [" + ((sender as ToolStripMenuItem).Text) + "]");
}

先写个子方法，根据variable name读数据库好了
