    這篇文章主要介紹了C#實(shí)現(xiàn)winform自動(dòng)關(guān)閉MessageBox對(duì)話框的方法,實(shí)例分析了C#中MessageBox對(duì)話框的相關(guān)操作技巧,需要的朋友可以參考下
    本文實(shí)例講述了C#實(shí)現(xiàn)winform自動(dòng)關(guān)閉MessageBox對(duì)話框的方法。分享給大家供大家參考。具體實(shí)現(xiàn)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(dòng)關(guān)閉MessageBox窗口", "MessageBox");
    }
    private void StartKiller()
    {
    Timer timer = new Timer();
    timer.Interval = 3000; //3秒啟動(dòng)
    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(biāo)題，找到MessageBox的窗口
    IntPtr ptr = FindWindow(null, "MessageBox");
    if (ptr != IntPtr.Zero)
    {
    //找到則關(guān)閉MessageBox窗口
    PostMessage(ptr, WM_CLOSE, IntPtr.Zero, IntPtr.Zero);
    }
    }
    }
    }
    希望本文所述對(duì)大家的C#程序設(shè)計(jì)有所幫助
