我要评论本文实例讲述了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。
