NotifyIcon控件有一个属性contextMenuStrip;
在托一个contextMenuStrip(右键菜单)控件;
用NotifyIcon控件的属性contextMenuStrip指向右键菜单的ID; Icon1 = notifyIcon1.Icon;
notifyIcon1.Icon = Icon;
//notifyIcon1.Icon = mNetTrayIcon ;
notifyIcon1.Text = "合同管理系统";
notifyIcon1.Visible = true;
//定义一个MenuItem数组,并把此数组同时赋值给ContextMenu对象
MenuItem[] mnuItms = new MenuItem[3];
mnuItms[0] = new MenuItem();
mnuItms[0].Text = "打开系统";
mnuItms[0].Click += new System.EventHandler(this.showMainForm);
mnuItms[1] = new MenuItem("-");
mnuItms[2] = new MenuItem();
mnuItms[2].Text = "退出系统";
mnuItms[2].Click += new System.EventHandler(this.ExitSelect);
mnuItms[2].DefaultItem = true;
notifyiconMnu = new ContextMenu(mnuItms);
notifyIcon1.ContextMenu = notifyiconMnu;
