WinForm实现程序一段时间不运行自动关闭的方法

本文实例讲述了winform实现程序一段时间不运行自动关闭的方法。分享给大家供大家参考。具体实现方法如下：

using system;
using system.collections.generic;
using system.componentmodel;
using system.data;
using system.drawing;
using system.text;
using system.windows.forms;
using system.net;
using system.io;
using system.security.cryptography.x509certificates;
using system.net.security;
namespace demodatagridview
{
 public partial class form3 : form, imessagefilter
 {
  private int m_waitminute = 0;
  system.windows.forms.timer mytimer;
  public form3()
  {
   initializecomponent();
   mytimer = new timer();
   mytimer.interval = 1000;
   mytimer.tick += new eventhandler(mytimer_tick);
   application.idle += new eventhandler(application_idle);
  }
  void mytimer_tick(object sender, eventargs e)
  {
   if (m_waitminute < 60)
   {
    mytimer.enabled = true;
    mytimer.interval = 10000; //10秒
    m_waitminute += 1;
    // this.opacity = 1.0 - convert.todouble(m_waitminute / 60.0);
   }
   else
   {
    mytimer.enabled = false;
   }
  }
  void application_idle(object sender, eventargs e)
  {
   if (m_waitminute == 0)
   {
    system.io.file.writealltext("d:\\1.txt", datetime.now.tostring());
    mytimer.start();
   }
   else
   {
    if (m_waitminute >= 6)
    {
     system.io.file.writealltext("d:\\2.txt", datetime.now.tostring());
     this.close();
    }
   }
  }
  public bool prefiltermessage(ref message m)
  {
   if (m_waitminute != 0)
   {
    m_waitminute = 0;
    mytimer.enabled = false;
    return true;
   }
   return false;
  }
 }
}

希望本文所述对大家的c#程序设计有所帮助。
