C# WinForm窗口最小化到系統托盤

C#編寫最小化時隱藏爲任務欄圖標的Window appllication.
1.設置WinForm窗體屬性showinTask=false

2.加notifyicon控件notifyIcon1，爲控件notifyIcon1的屬性Icon添加一個icon圖標。

3.添加窗體最小化事件(首先需要添加事件引用)：

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

//上面一行是主窗體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.添加點擊圖標事件(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.可以給notifyIcon添加右鍵菜單：

主窗體中拖入一個ContextMenu控件NicontextMenu  ，點中控件，在上下文菜單中添加菜單，notifyIcon1的ContextMenu行爲中選中NicontextMenu  作爲上下文菜單。

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  =  "隱藏";
this.menuItem_Hide.Click  +=  new  System.EventHandler(this.menuItem_Hide_Click);
//  
//  menuItem_Show
//  
this.menuItem_Show.Index  =  1;
this.menuItem_Show.Text  =  "顯示";
this.menuItem_Show.Click  +=  new  System.EventHandler(this.menuItem_Show_Click);
//  
//  menuItem_Aubot
//  
this.menuItem_Aubot.Index  =  2;
this.menuItem_Aubot.Text  =  "關於";
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;
e.Cancel  =  true;  
}
protected  override  void  OnClosing(CancelEventArgs  e)
{
//this.ShowInTaskbar  =  false;
this.WindowState  =  FormWindowState.Minimized;
e.Cancel  =  true;  
}

private  void  CloseCtiServer()
{
timer.Enabled  =  false;
DJ160API.DisableCard();
this.NotifyIcon.Visible  =  false;
this.Close();
this.Dispose();
Application.Exit();
}

private  void  HideCtiServer()
{
this.Hide();

}

private  void  ShowCtiServer()
{
this.Show();
this.WindowState  =  FormWindowState.Normal;
this.Activate();

}
private  void  CtiManiForm_Closing(object  sender,  System.ComponentModel.CancelEventArgs  e)
{
this.CloseCtiServer();
}

private  void  menuItem_Show_Click(object  sender,  System.EventArgs  e)
{
this.ShowCtiServer();
}

private  void  menuItem_Aubot_Click(object  sender,  System.EventArgs  e)
{

}

private  void  menuItem_Exit_Click(object  sender,  System.EventArgs  e)
{
this.CloseCtiServer();
}

private  void  menuItem_Hide_Click(object  sender,  System.EventArgs  e)
{
this.HideCtiServer();
}

private  void  CtiManiForm_SizeChanged(object  sender,  System.EventArgs  e)
{
if  (this.WindowState  ==  FormWindowState.Minimized)
{
this.HideCtiServer();
}

}

private  void  notifyIcon1_DoubleClick(object  sender,  System.EventArgs  e)
{                                
this.ShowCtiServer();
}
