C#编写最小化时隐藏为任务栏图标的Windowappllication.
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+=newSystem.EventHandler(this.Form1_SizeChanged);
//上面一行是主窗体InitializeComponent()方法中需要添加的引用
privatevoidForm1_SizeChanged(objectsender,EventArgse){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)：
privatevoidnotifyIcon1_Click(objectsender,EventArgse){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=newSystem.Windows.Forms.NotifyIcon(this.components);this.NicontextMenu=newSystem.Windows.Forms.ContextMenu();this.menuItem_Hide=newSystem.Windows.Forms.MenuItem();this.menuItem_Show=newSystem.Windows.Forms.MenuItem();this.menuItem_Aubot=newSystem.Windows.Forms.MenuItem();this.menuItem_Exit=newSystem.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+=newSystem.EventHandler(this.notifyIcon1_DoubleClick);this.notifyIcon1.Click+=newSystem.EventHandler(this.notifyIcon1_Click);
this.NicontextMenu.MenuItems.AddRange(newSystem.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+=newSystem.EventHandler(this.menuItem_Hide_Click);////menuItem_Show//this.menuItem_Show.Index=1;this.menuItem_Show.Text="显示";this.menuItem_Show.Click+=newSystem.EventHandler(this.menuItem_Show_Click);////menuItem_Aubot//this.menuItem_Aubot.Index=2;this.menuItem_Aubot.Text="关
