关于最小化到托盘的问题
这是我在关闭事件中写的代码, 
private void ChangeFrm_FormClosing(object sender, FormClosingEventArgs e)
  {
  if (e.CloseReason == CloseReason.UserClosing)
  {
  e.Cancel = true;
  this.Hide();
  }
  else
  {
  e.Cancel = false;
  }
}
现在出现个问题 当我运行我写的程序后 电脑不能关机,退出程序后 就可以关机了 这是怎么回事啊,求指点下。

[解决办法]

C# code
    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();    }
