記錄asp.net網站停止運行原因的代碼

記錄網站是什么原因導致停止運行還是有必要的，下面是具體的實現方式。

                PRotected void application_End(object sender, EventArgs e)        {            RecordEndReason();        }        /// <summary>        /// 記錄網站停止運行原因        /// </summary>        protected void RecordEndReason()        {            HttpRuntime runtime = (HttpRuntime)typeof(System.Web.HttpRuntime).InvokeMember("_theRuntime", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.GetField,                null,                null,                null);            if (runtime == null)                return;            string shutDownMessage = (string)runtime.GetType().InvokeMember("_shutDownMessage",                System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.GetField,                null,                runtime,                null);            string shutDownStack = (string)runtime.GetType().InvokeMember(                "_shutDownStack",                System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.GetField,                null,                runtime,                null);            string reasonString="網站Application_End，停止運行,shutDownMessage=" + shutDownMessage + ",shutDownStack=" + shutDownStack;            LogHelper.WriteErrorLog(reasonString,null);            LogHelper.WriteSmtp(reasonString, null);            //以下方法將重啟的原因和重啟時的堆棧信息記錄到了windows的事件查看器中,當然你也可以記錄到文本文件中。            //EventLog log = new EventLog();            //log.Source = "ASP.NET 2.0.50727.0";            //log.WriteEntry(String.Format("/r/n/r/n_shutDownMessage={0}/r/n/r/n_shutDownStack={1}", shutDownMessage, shutDownStack), EventLogEntryType.Information);        }
