It is necessary to keep track of what causes the site to stop running, and here is how to implement it. The   code is as follows: protected void Application_End (object sender, EventArgs e)   {  Recordendreason (); }  &N Bsp <summary> ///Record website stop running reason  ///</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= " Website Application_End, stop running, shutdownmessage= "+ Shutdownmessage +", shutdownstack= "+ shutdownstack;  Loghelper.writeerrorlog (reasonstring,null);  loghelper.writesmtp (reasonstring, NULL); // The following methods record the reason for the reboot and the stack information when it restarts in Windows Event Viewer, but you can also record it in a text file.  //eventlog log = new EventLog (); //log. Source = "asp.net 2.0.50727.0"; //log. WriteEntry (String.Format ("Rnrn_shutdownmessage={0}rnrn_shutdownstack={1}", Shutdownmessage, Shutdownstack), eventlogentrytype.information); }
