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。
