C#實現winform自動關閉MessageBox對話框的方法

這篇文章主要介紹了C#實現winform自動關閉MessageBox對話框的方法,實例分析了C#中MessageBox對話框的相關操作技巧,需要的朋友可以參考下

本文實例講述了C#實現winform自動關閉MessageBox對話框的方法。分享給大家供大家參考。具體實現方法如下：

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秒鐘后自動關閉MessageBox窗口", "MessageBox");

}

private void StartKiller()

{

Timer timer = new Timer();

timer.Interval = 3000; //3秒啟動

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的標題，找到MessageBox的窗口

IntPtr ptr = FindWindow(null, "MessageBox");

if (ptr != IntPtr.Zero)

{

//找到則關閉MessageBox窗口

PostMessage(ptr, WM_CLOSE, IntPtr.Zero, IntPtr.Zero);

}

}

}

}

希望本文所述對大家的C#程序設計有所幫助
