[导入]C#实现WinForm窗口最小化到系统托盘

C#编写最小化时隐藏为任务栏图标的 Window appllication.  

1.设置WinForm窗体属性showinTask=false

2.加notifyicon控件notifyIcon1，为控件notifyIcon1的属性Icon添加一个icon图标。

3.添加窗体最小化事件(首先需要添加事件引用)：

this.SizeChanged += new System.EventHandler(this.Form1_SizeChanged);

//上面一行是主窗体InitializeComponent()方法中需要添加的引用

private void Form1_SizeChanged(object sender, EventArgs e)
{
    if(this.WindowState == FormWindowState.Minimized)
    {
       this.Hide();
       this.notifyIcon1.Visible=true;
    }
}

4.添加点击图标事件(首先需要添加事件引用)：

private void notifyIcon1_Click(object sender, EventArgs e)
{
    this.Visible = true;
    this.WindowState = FormWindowState.Normal;
    this.notifyIcon1.Visible = false;
}

5.可以给notifyIcon添加右键菜单：

主窗体中拖入一个ContextMenu控件NicontextMenu，点中控件，在上下文菜单中添加菜单，notifyIcon1的ContextMenu行为中选中NicontextMenu 作为上下文菜单。

this.notifyIcon1 = new System.Windows.Forms.NotifyIcon(this.components);
this.NicontextMenu = new System.Windows.Forms.ContextMenu();
this.menuItem_Hide = new System.Windows.Forms.MenuItem();
this.menuItem_Show = new System.Windows.Forms.MenuItem();
this.menuItem_Aubot = new System.Windows.Forms.MenuItem();
this.menuItem_Exit = new System.Windows.Forms.MenuItem();  

this.notifyIcon1.ContextMenu = this.NicontextMenu;
this.notifyIcon1.Icon = ((System.Drawing.Icon)(resources.GetObject( "NotifyIcon.Icon ")));
this.notifyIcon1.Text = " ";
this.notifyIcon1.Visible = true;
this.notifyIcon1.DoubleClick += new System.EventHandler(this.notifyIcon1_DoubleClick);
this.notifyIcon1.Click += new System.EventHandler(this.notifyIcon1_Click);

this.NicontextMenu.MenuItems.AddRange(

    new System.Windows.Forms.MenuItem[]
    {
          this.menuItem_Hide,
          this.menuItem_Show,
          this.menuItem_Aubot,
          this.menuItem_Exit
    }
);

//    
//       menuItem_Hide
//    
this.menuItem_Hide.Index = 0;
this.menuItem_Hide.Text = "隐藏 ";
this.menuItem_Hide.Click += new System.EventHandler(this.menuItem_Hide_Click);
//    
//       menuItem_Show
//    
this.menuItem_Show.Index = 1;
this.menuItem_Show.Text = "显示 ";
this.menuItem_Show.Click += new System.EventHandler(this.menuItem_Show_Click);
//    
//       menuItem_Aubot
//    
this.menuItem_Aubot.Index = 2;
this.menuItem_Aubot.Text = "关于 ";
this.menuItem_Aubot.Click += new System.EventHandler(this.menuItem_Aubot_Click);
//    
//       menuItem_Exit
//    
this.menuItem_Exit.Index = 3;
this.menuItem_Exit.Text = "退出 ";
this.menuItem_Exit.Click += new System.EventHandler(this.menuItem_Exit_Click);

protected  override  void  OnClosing(CancelEventArgs e)

   this.ShowInTaskbar = false;
   this.WindowState = FormWindowState.Minimized;

   }
}

    this.ShowCtiServer();
}
