应用程序有bug崩溃重启的案例

1、程序主界面代码

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;namespace WindowsFormsAppThreadRestart
{
    static class Program
    {
        public static log4net.ILog Log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().GetType());
        /// <summary>
        /// 应用程序的主入口点。
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
            Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException);
            AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new Form1());
        }
        static void Application_ThreadException(object sender, System.Threading.ThreadExceptionEventArgs e)
        {
            Log.Error(e.Exception);
            //throw new Exception("线程未知异常", e.Exception);
            if (MessageBox.Show($"异常信息：{e.Exception.Message}，是否重启应用程序或者联系开发工程师？", "线程异常", MessageBoxButtons.YesNo, MessageBoxIcon.Error) == DialogResult.Yes)
            {
                CmdStartProc1(Application.ExecutablePath, "<nul");
                //StartProc2();
               Application.Exit();
            }
        }        static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
        {
            Exception ex = e.ExceptionObject as Exception;
            Log.Error(ex);            if (MessageBox.Show($"异常信息：{ex.Message}，是否重启应用程序或者联系开发工程师？", "应用程序异常", MessageBoxButtons.YesNo, MessageBoxIcon.Error) == DialogResult.Yes)
            {
                CmdStartProc1(Application.ExecutablePath, "<nul");
                Application.Exit();
            }
        }        /// <summary>
        /// 在命令行窗口中执行
        /// </summary>
        /// <param name="sExePath"></param>
        /// <param name="sArguments"></param>
        static void CmdStartProc1(string sExePath, string sArguments)
        {
            Process p = new Process();
            p.StartInfo.FileName = "cmd.exe";
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardInput = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.RedirectStandardError = true;
            p.StartInfo.CreateNoWindow = true;//true表示不显示黑框，false表示显示dos界面 
            p.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
            p.Start();
            p.StandardInput.WriteLine(sExePath);
            p.StandardInput.WriteLine("exit");
            p.Close();            System.Threading.Thread.Sleep(100);//必须等待，否则重启的程序还未启动完成；根据情况调整等待时间
        }        static void StartProc2()
        {
            //重启程序，需要时加上重启的参数
            ProcessStartInfo cp = new ProcessStartInfo();
            cp.FileName = Application.ExecutablePath;
            //cp.Arguments = "cmd params";
            cp.UseShellExecute = true;
            Process.Start(cp);
        }
    }
}2、窗体界面的代码
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;namespace WindowsFormsAppThreadRestart
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }        private void button1_Click(object sender, EventArgs e)
        {
            int a = 0;
            int b = 9 / a;
        }
    }
}
