C#实现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;

  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();

  }
