本文实例讲述了WinForm实现最小化到系统托盘方法。分享给大家供大家参考。具体分析如下：

有个叫NotifyIcon的控件

1、建个WinForm项目，其它操作略过。
2、拉个NotifyIcon控件，将属性Visable设置成False，在Text属性上随便填些文件。
3、实现Form的SizeChanged事件，代码如下：

if(this.WindowState == FormWindowState.Minimized) //判断是否最小化{this.ShowInTaskbar = false; //不显示在系统任务栏notifyIcon.Visible = true; //托盘图标可见}

4、实现NotifyIcon控件的DoubleClick事件，代码如下：

if(this.WindowState == FormWindowState.Minimized){this.ShowInTaskbar = true; //显示在系统任务栏this.WindowState = FormWindowState.Normal; //还原窗体notifyIcon.Visible = false; //托盘图标隐藏}

例题：

private ContextMenu notifyiconMnu;#region 最小化到任务栏/// <summary>/// 最小化到任务栏/// </summary>private void Initializenotifyicon(){ //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 = "显示窗口"; mnuItms[0].Click += new System.EventHandler(this.notifyIcon1_showfrom); 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; //为托盘程序加入设定好的ContextMenu对象 }private void notifyIcon1_DoubleClick(object sender, EventArgs e){ if (this.WindowState == FormWindowState.Minimized) { this.Show(); this.ShowInTaskbar = true; this.WindowState = FormWindowState.Normal; notifyIcon1.Visible = false; }}public void notifyIcon1_showfrom(object sender, System.EventArgs e){ if (this.WindowState == FormWindowState.Minimized) { this.Show(); this.ShowInTaskbar = true; this.WindowState = FormWindowState.Normal; notifyIcon1.Visible = false; }}public void ExitSelect(object sender, System.EventArgs e){ //隐藏托盘程序中的图标 notifyIcon1.Visible = false; //关闭系统 this.Close(); this.Dispose(true);}#endregionprivate void Form_main_SizeChanged(object sender, EventArgs e){ if (this.WindowState == FormWindowState.Minimized) //判断是否最小化 { notifyIcon1.Visible = true; this.Hide(); this.ShowInTaskbar = false; Initializenotifyicon(); }}

希望本文所述对大家的C#程序设计有所帮助。
