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：
usingSystem;
usingSystem.Collections.Generic;
usingSystem.ComponentModel;
usingSystem.Data;
usingSystem.Drawing;
usingSystem.Text;
usingSystem.Windows.Forms;
usingSystem.Runtime.InteropServices;
namespaceWindowsApplication1
{
publicpartialclassAutoDeleteMessageBox:Form
{
[DllImport("user32.dll",EntryPoint="FindWindow",CharSet=CharSet.Auto)]
privateexternstaticIntPtrFindWindow(stringlpClassName,stringlpWindowName);
[DllImport("user32.dll",CharSet=CharSet.Auto)]
publicstaticexternintPostMessage(IntPtrhWnd,intmsg,IntPtrwParam,IntPtrlParam);
publicconstintWM_CLOSE=0x10;
publicAutoDeleteMessageBox()
{
InitializeComponent();
}
privatevoidbutton1_Click(objectsender,EventArgse)
{
StartKiller();
MessageBox.Show("3秒钟后自动关闭MessageBox窗口","MessageBox");
}
privatevoidStartKiller()
{
Timertimer=newTimer();
timer.Interval=3000;//3秒启动
timer.Tick+=newEventHandler(Timer_Tick);
timer.Start();
}
privatevoidTimer_Tick(objectsender,EventArgse)
{
KillMessageBox();
//停止Timer
((Timer)sender).Stop();
}
privatevoidKillMessageBox()
{
//按照MessageBox的标题，找到MessageBox的窗口
IntPtrptr=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。
