C#定时关闭窗体实例

本文实例讲述了c#定时关闭窗体的方法，分享给大家供大家参考。具体方法如下：

public partial class form2 : form 
{ 
private system.timers.timer timer = new system.timers.timer(); 

public form2() 
{ 
    initializecomponent(); 
    initstatus(); 
    timer.interval = 4000; 
    timer.elapsed += new system.timers.elapsedeventhandler(timer_elapsed); 
    timer.enabled = true; 
} 

void timer_elapsed(object sender, system.timers.elapsedeventargs e) 
{ 
    intptr hdlog = findwindow(null, "show"); 
    if (intptr.zero != hdlog) 
    {  
 intptr result; 
 enddialog(hdlog, out result); 
    } 
} 

private void initstatus() 
{ 
    this.panel1.controls.clear(); 

    form1 from1 = new form1(); 
    from1.toplevel = false; 
    from1.formborderstyle = formborderstyle.none; 

    this.panel1.controls.add(from1); 
    from1.show(); 
} 
[dllimport("user32.dll",setlasterror=true)] 
public static extern intptr findwindow(string lpclassname, string caption);

<span style="white-space:pre">  <span style="font-family: monospace; white-space: pre; background-color: rgb(240, 240, 240); ">[dllimport("user32.dll",setlasterror=true)]</span><br style="font-family: monospace; white-space: pre; background-color: rgb(240, 240, 240); "><span style="font-family: monospace; white-space: pre; background-color: rgb(240, 240, 240); ">        public static extern int postmessage(intptr hwnd, int message, intptr wparam, intptr lparam);</span> 
</span> 
 
 
        [dllimport("user32.dll",setlasterror=true)] 
        public static extern bool enddialog(intptr hdlg, out intptr nresult); 
 
        private void button1_click(object sender, eventargs e) 
        { 
            messagebox.show("corning", "show"); 
        } 
    }

希望本文所述对大家的c#程序设计有所帮助。
