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。
