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)：


	复制代码 代码如下:

	

	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。


	复制代码 代码如下:

	

	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();

	}
