winform 关于Messagebox自动定时关闭和自定义提示框总按钮上文本的问题的整理

如果要改变Messagebox上按钮的文本和自动关闭Messagebox提示框，一种方法是自定义一个winform窗口模仿替代Messagebox，变通的实现效果，另一种方法是通过调用系统的API来实现，因为C#没有对Messagebox提供相关的关闭方法。

第一种方法（自定义winform窗口实现）：

            }

            if (MIcon == MyIcon.RecycleBinEmpty)

            }

            if (MIcon == MyIcon.Stop)
            {
                MessageBeep(0);
                frmIcon = Icon.FromHandle(largeIcon[27]);
            }

            if (MIcon == MyIcon.User)

            {
                MessageBeep(30);
                frmIcon = Icon.FromHandle(largeIcon[217]);
            }
        }

        void newMessageBox_Paint(object sender, PaintEventArgs e)
        {
            Graphics g = e.Graphics;
            Rectangle frmTitleL = new Rectangle(0, 0, (newMessageBox.Width / 2), 22);
            Rectangle frmTitleR = new Rectangle((newMessageBox.Width / 2), 0, (newMessageBox.Width / 2), 22);
            Rectangle frmMessageBox = new Rectangle(0, 0, (newMessageBox.Width - 1), (newMessageBox.Height - 1));
            LinearGradientBrush frmLGBL = new LinearGradientBrush(frmTitleL, Color.FromArgb(87, 148, 160), Color.FromArgb(209, 230, 243), LinearGradientMode.Horizontal);
            LinearGradientBrush frmLGBR = new LinearGradientBrush(frmTitleR, Color.FromArgb(209, 230, 243), Color.FromArgb(87, 148, 160), LinearGradientMode.Horizontal);

        }

        private void StartTimer(int interval)
        {
            Timer timer = new Timer();
            timer.Interval = interval;
            timer.Tick += new EventHandler(Timer_Tick);
            timer.Enabled = true;
        }

        private void Timer_Tick(object sender, EventArgs e)
        {
            newMessageBox.Close();
            //停止计时器
            ((Timer)sender).Enabled = false;
        }

第二种方法（调用API实现）：

1、实现定时关闭Messagebox，通过Messagebox对话框的标题查找相应的句柄来进行关闭操作

public class MessageBoxTimeOut
    {
        private string _caption;
        private string username;
        private string pwd;
        public DialogResult Show(int timeout, string text, string caption, MessageBoxButtons buttons)
        {
            this._caption = caption;
            StartTimer(timeout);
            DialogResult dr = MessageBox.Show(text, caption, buttons, MessageBoxIcon.Asterisk, MessageBoxDefaultButton.Button1);
            return dr;
        }
        private void StartTimer(int interval)
        {
            Timer timer = new Timer();
            timer.Interval = interval;
            timer.Tick += new EventHandler(Timer_Tick);
            timer.Enabled = true;
        }
        private void Timer_Tick(object sender, EventArgs e)
        {
            KillMessageBox();
            //停止计时器
            ((Timer)sender).Enabled = false;
        }
        [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 void KillMessageBox()
        {
            //查找MessageBox的弹出窗口,注意对应标题
            IntPtr ptr = FindWindow(null, this._caption);
            if (ptr != IntPtr.Zero)
            {
                //查找到窗口则关闭
                PostMessage(ptr, WM_CLOSE, IntPtr.Zero, IntPtr.Zero);
            }
        }
    }

2、关闭Messagebox对话框中按钮的文本文字

        private delegate bool EnumChildProc(IntPtr hWnd, IntPtr lParam);

        private const int WM_TIMER = 0x0113;
        private const int WM_USER = 0x400;
        private const int DM_GETDEFID = WM_USER + 0;

        private const int MBOK = 1;
        private const int MBCancel = 2;
        private const int MBAbort = 3;
        private const int MBRetry = 4;
        private const int MBIgnore = 5;
        private const int MBYes = 6;
        private const int MBNo = 7;
