记录asp.net网站停止运行原因的代码

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);

        }
