C#编写最小化时隐藏为任务栏图标的Window appllication

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();
}

 

 

 

 

 

看到网上的一些方法是利用重写窗体的Closing过程来完成的,代码如下:

//添加NotifyIcon控件

private System.Windows.Forms.NotifyIcon notifyIcon1;

//设置属性

this.notifyIcon1 = new System.Windows.Forms.NotifyIcon(this.components);

this.Closing +=new CancelEventHandler(Form1_Closing);

this.notifyIcon1.Icon = ((System.Drawing.Icon)(resources.GetObject("notifyIcon1.Icon")));
this.notifyIcon1.Text = "网页分析器";
this.notifyIcon1.Visible = false;

this.notifyIcon1.MouseDown += new System.Windows.Forms.MouseEventHandle(this.notifyIcon1_MouseDown);

//重写Closing过程

this.Closing +=new CancelEventHandler(Form1_Closing);

 

private void Form1_Closing(object sender, System.ComponentModel.CancelEventArgs e)

{
    this.Hide();

    this.notifyIcon1.Visible=true;
    e.Cancel=true;
}

 

private void notifyIcon1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e) {

   this.show();
   this.Activate();

   this.notifyIcon1.Visible=false;

}

 

 

但是这样就没有最小化的效果了，其实我们可以通过重写Deactivate事件来达到"最小化"的效果

代码：

~~~

this.Deactivate += new System.EventHandler(this.Form1_Mini);

private void Form1_Mini(object sender, System.EventArgs e)
{
   if(this.WindowState==FormWindowState.Minimized)
   {
       this.Visible=false;

       this.notifyIcon1.Visible=true;
   }

}

 

private void notifyIcon1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e) {

   this.Visible=true;

   this.WindowState=FormWindowState.Normal;
   this.Activate();

   this.notifyIcon1.Visible=false;

}

 

这样就有最小化的效果了，不过还要解决最小化方向的问题~~~
