  • .Net下Unhandled Exception的捕获

    C# 处理unhandled Exception方式如下:
    1.    在程序的Main()方法中增加如下代码。
          //处理线程未处理的异常
       Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException);
       //处理系统未处理的异常
       AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException);
          //运行程序
       Application.Run(new frmServerMain());
       
    2.    方法:
            static void Application_ThreadException(object sender, System.Threading.ThreadExceptionEventArgs e)
            {
                string str = "";
                Exception error = e.Exception as Exception;
                if (error != null)
                {
                    str = string.Format("Application unhandled exception. ExceptionType:{0} Exception Message: {1} StackTrace:{2} ",
                         error.GetType().Name, error.Message, error.StackTrace);
                }
                else
                {
                    str = string.Format("Application Thread Exception Msg:{0}", e);
                }
                WriteErrInfo(str);
            }

            static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
            {

                string str = "";

                Exception error = e.ExceptionObject as Exception;
                if (error != null)
                {
                    str = string.Format("Application UnhandledException:{0}; StackTrace:{1}", error.Message, error.StackTrace);
                }
                else
                {
                    str = string.Format("Application UnhandledError:{0}", e);
                }
                WriteErrInfo(str);
            }

            static void WriteErrInfo(string vErrMsg)
            {
                using (System.IO.FileStream fs = new System.IO.FileStream(Application.StartupPath + "\Log\TestException.log",
                    System.IO.FileMode.Append, System.IO.FileAccess.Write))
                {
                    using (System.IO.StreamWriter w = new System.IO.StreamWriter(fs,System.Text.Encoding.UTF8))
                    {
                        w.WriteLine(vErrMsg); DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss");
                    }
                }
            }
