C# winform 全局異常處理

廢話不說，直接上代碼：

namespace HeatingBalance
{
    static class Program
    {
        private static readonly ILog log = LogManager.GetLogger(typeof(Program));
        /// <summary>
        /// 應用程序的主入口點。
        /// </summary>
        [STAThread]
        static void Main()
        {
            try
            {
                log.Info("start application.");

                //設置應用程序處理異常方式：ThreadException處理
                Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
                //處理UI線程異常
                Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_UIThreadException);
                //處理非UI線程異常
                AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);

                #region 應用程序的主入口點
                Application.EnableVisualStyles();
                Application.SetCompatibleTextRenderingDefault(false);

                // 啓動歡迎窗體
                Application.Run(new WelcomeForm());

                //InfoAction infoAction = new InfoAction();

                //// 啓動信息窗口
                //Application.Run(new HeatingPowerSettingForm(infoAction));

                //if (ActionType.Start == infoAction.InfoActionType)
                //{
                //    // 啓動主窗體
                //    Application.Run(new MainForm());
                //    return;

                FunctionMode functionMode = new FunctionMode(SoftMode.HeatingSource);

                Application.Run(new FunctiongSelectForm(functionMode));

                MainForm mainForm = new MainForm();
                // mainForm.SoftMode = functionMode.SoftMode;

                // 啓動主窗體
                Application.Run(mainForm);
                #endregion
            }
            catch (Exception ex)
            {
                RecordExceptionMsg(ex, string.Empty);

log4net怎麼找，你們百度，嘿嘿
