Winform 主程序入口中记录并捕获全局异常

在做一些应用中，根据实际的需求情况，网上也收了些资料。这个对查找程序中的bug及出现的一些问题能很好排查，找到问题原因！自己记录下

 static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {

            LogHepler log = new LogHepler();

            try
            {
             //处理未捕获的异常
             Application.SetUnhandledExceptionMode(UnhandledExceptionMode.CatchException);
             //处理UI线程异常
             Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException);
             //处理非UI线程异常
             AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
