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);
