WinForm程序全局捕捉异常处理办法

如何全局捕捉Winform程序异常呢，当然是从程序启动入口的Program类下的Main()方法定义了，下面看下这个类怎么写的吧

    static class Program
    {
        static string RunFormFullName
        {
            get
            {
                string setRunFormFullName = CIPACE.Sys.Configuration.RunFormFullName;
                if (setRunFormFullName == null)
                    setRunFormFullName = DigiForm.SETRUNFORMFULLNAME;

                return setRunFormFullName;
            }
        }
        /// <summary>
        ///   应用程序的主入口点。
        /// </summary>
        public static ApplicationContext context;

        [STAThread]
        private static void Main()
        {
            try
            {
                //处理未捕获的异常
                Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
                //处理UI线程异常
                Application.ThreadException += Application_ThreadException;
                //处理非UI线程异常
                AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;

                var aProcessName = Process.GetCurrentProcess().ProcessName;
                if ((Process.GetProcessesByName(aProcessName)).GetUpperBound() > )
                {
                    MessageBox.Show(@"系统已经在运行中，如果要重新启动，请从进程中关闭...", @"系统警告", MessageBoxButtons.OK, MessageBoxIcon.Asterisk);
                }
                else
                {
                    Application.EnableVisualStyles();
                    Application.SetCompatibleTextRenderingDefault(false);
                    context = new ApplicationContext();
                    Application.Idle += Application_Idle; //注册程序运行空闲去执行主程序窗体相应初始化代码
                    Application.Run(context);
                }
            }
            catch (Exception ex)
            {
                LogNet.Log.WriteLog("Main", ex);
                MessageBox.Show("系统出现异常：" + (ex.Message + " " + (ex.InnerException != null && ex.InnerException.Message != null && ex.Message != ex.InnerException.Message ? ex.InnerException.Message : ""))+",请重启程序。");

                DigiForm digiForm = new DigiForm();
                digiForm.UpdateAppSettings(DigiForm.RUNFORMFULLNAME, DigiForm.LOGINFORMFULLNAME);
            }
        }

        private static void Application_Idle(object sender, EventArgs e)
        {
            Application.Idle -= Application_Idle;
            if (context.MainForm == null)
            {
                Form form = new LoginForm();
                context.MainForm = form;
                form.Show();
            }
        }

        private static void Application_ThreadException(object sender, ThreadExceptionEventArgs e)
        {
            var ex = e.Exception;
            if (ex != null)
            {
                LogNet.Log.WriteLog("Application_ThreadException", ex);
            }

            MessageBox.Show("系统出现异常：" + (ex.Message + " " + (ex.InnerException != null && ex.InnerException.Message != null && ex.Message != ex.InnerException.Message ? ex.InnerException.Message : "")));
        }

        private static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
        {
            var ex = e.ExceptionObject as Exception;
            if (ex != null)
            {
                LogNet.Log.WriteLog("CurrentDomain_UnhandledException", ex);
            }

            MessageBox.Show("系统出现异常：" + (ex.Message + " " + (ex.InnerException != null && ex.InnerException.Message != null && ex.Message != ex.InnerException.Message ? ex.InnerException.Message : "")));
        }

    }
