C#实现winform自动关闭MessageBox对话框的方法

本文实例讲述了C#实现winform自动关闭MessageBox对话框的方法。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.Runtime.InteropServices;
namespace WindowsApplication1
{
public partial class AutoDeleteMessageBox : Form
{
 [DllImport("user32.dll", EntryPoint = "FindWindow", CharSet = CharSet.Auto)]
 private extern static IntPtr FindWindow(string lpClassName, string lpWindowName);
 [DllImport("user32.dll", CharSet = CharSet.Auto)]
 public static extern int PostMessage(IntPtr hWnd, int msg, IntPtr wParam, IntPtr lParam);
 public const int WM_CLOSE = 0x10;
 public AutoDeleteMessageBox()
 {
  InitializeComponent();
 }
 private void button1_Click(object sender, EventArgs e)
 {
  StartKiller();
  MessageBox.Show("3秒钟后自动关闭MessageBox窗口", "MessageBox");
 }
 private void StartKiller()
 {
  Timer timer = new Timer();
  timer.Interval = 3000; //3秒启动
  timer.Tick += new EventHandler(Timer_Tick);
  timer.Start();
 }
 private void Timer_Tick(object sender, EventArgs e)
 {
  KillMessageBox();
  //停止Timer
  ((Timer)sender).Stop();
 }
 private void KillMessageBox()
 {
  //按照MessageBox的标题，找到MessageBox的窗口
  IntPtr ptr = FindWindow(null, "MessageBox");
  if (ptr != IntPtr.Zero)
  {
   //找到则关闭MessageBox窗口
   PostMessage(ptr, WM_CLOSE, IntPtr.Zero, IntPtr.Zero);
  }
 }
}
}

希望本文所述对大家的C#程序设计有所帮助。
