用c#为listview 的项添加右键菜单，菜单仅在选中项弹出

//首先，声明一个ContextMenuStrip控件，并初始化它。private ContextMenuStrip strip = new ContextMenuStrip();//1strip.Items.Add(\"item1\");//2strip.Items.Add(\"item2\"); //3//（当然2，3代码的位置需要调整）//然后，声明一个鼠标事件。listViewtcmedicineSearch.MouseClick += new MouseEventHandler(listViewtcmedicineSearchMouseClick);private void listViewtcmedicineSearchMouseClick(object sender,MouseEventArgs e){if (e.Button==MouseButtons.Right){strip.Show(listViewtcmedicineSearch, e.Location);//鼠标右键按下弹出菜单}}

就是这么简单。
