ContextMenuStrip 动态添加多级子菜单(一)

有如下代码看过应该就明白了：

((ToolStripDropDownItem)contextMenuStrip1.Items[1]).DropDownItems.Add("正常");


((ToolStripDropDownItem)(((ToolStripDropDownItem)contextMenuStrip1.Items[


或：


ToolStripDropDownItem ts = ((ToolStripDropDownItem)contextMenuStrip1.Items["aToolStripMenuItem"]);
            ts = ((ToolStripDropDownItem)ts.DropDownItems["eToolStripMenuItem"]);
            ts.DropDownItems.Add(new ToolStripMenuItem("h"));"aToolStripMenuItem"]).DropDownItems["eToolStripMenuItem"])).DropDownItems.Add(new ToolStripMenuItem("h"));

((ToolStripDropDownItem)(((ToolStripDropDownItem)contextMenuStrip1.Items[1]).DropDownItems[1])).DropDownItems.Add("OK");

            contextMenuStrip1.Items.Add("编辑");
            contextMenuStrip1.Items.Add("状态");
            ((ToolStripDropDownItem)contextMenuStrip1.Items[1]).DropDownItems.Add("正常");
            ((ToolStripDropDownItem)contextMenuStrip1.Items[1]).DropDownItems.Add("维修");
            ((ToolStripDropDownItem)contextMenuStrip1.Items[1]).DropDownItems.Add("建设中");
            ((ToolStripDropDownItem)(((ToolStripDropDownItem)contextMenuStrip1.Items[1]).DropDownItems[0])).DropDownItems.Add("hi");
            ((ToolStripDropDownItem)(((ToolStripDropDownItem)(((ToolStripDropDownItem)contextMenuStrip1.Items[1]).DropDownItems[0])).DropDownItems[0])).DropDownItems.Add("hao hi");

效果图如下：
