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;            }        }        /// 
        ///   应用程序的主入口点。        /// 
        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(0) > 0)                {                    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 : "")));        }    }
