C#教程之C#实现winform自动关闭MessageBox对话框的方

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。
