C#MessageBox自动关闭窗口

1：MessageBox弹出的模式窗口会先阻塞掉它的父级线程.所以我们可以考虑在MessageBox前先增加一个用于"杀"掉MessageBox窗口的线程.因为需要在规定时间内"杀"掉窗口

解决：可以考虑在MessageBox前先增加一个用于"杀"掉MessageBox窗口的线程.因为需要在规定时间内"杀"掉窗口,所以我们可以直接考虑使用Timer类.

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 LeafSoft.Units{ class KillMessageBox { [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 KillMessageBox() { } public string caption="错误"; public void StartKiller() { Timer timer = new Timer(); timer.Interval = 6000; //3秒启动 timer.Tick += new EventHandler(Timer_Tick); timer.Start(); } private void Timer_Tick(object sender, EventArgs e) { KillBoxMethod(); //停止Timer ((Timer)sender).Stop(); } public void KillBoxMethod() { //按照MessageBox的标题，找到MessageBox的窗口 IntPtr ptr = FindWindow(null, caption); if (ptr != IntPtr.Zero) { //找到则关闭MessageBox窗口 PostMessage(ptr, WM_CLOSE, IntPtr.Zero, IntPtr.Zero); } }

}}

 2：每次在使用MessageBox.Show()之前先用创建KillMessageBox对象实例

KillMessageBox killbox = new KillMessageBox(); killbox.caption = "异常";//caption变量为窗口的标题 可以设置默认值 killbox.StartKiller(); MessageBox.Show("你好", "异常");
