记录网站是什么原因导致停止运行还是有必要的，下面是具体的实现方式。
protected void Application_End(object sender, EventArgs e){RecordEndReason();}/// <summary>/// 记录网站停止运行原因/// </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="网站Application_End，停止运行,shutDownMessage=" + shutDownMessage + ",shutDownStack=" + shutDownStack;LogHelper.WriteErrorLog(reasonString,null);LogHelper.WriteSmtp(reasonString, null);//以下方法将重启的原因和重启时的堆栈信息记录到了windows的事件查看器中,当然你也可以记录到文本文件中。//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);}
