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。
