在站点执行Application_End事件中添加记录方法。在Global.asax.cs文件中添加如下代码即可：
void Application_End(object sender, EventArgs e){ // Code that runs on application shutdown RecordEndReason();}protected void RecordEndReason(){ HttpRuntime runtime = (HttpRuntime)typeof(System.Web.HttpRuntime).InvokeMember("_theRuntime", BindingFlags.NonPublic | BindingFlags.Static | BindingFlags.GetField, null, null, null); if (runtime == null) return; string shutDownMessage = (string)runtime.GetType().InvokeMember("_shutDownMessage", BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.GetField, null, runtime, null); string shutDownStack = (string)runtime.GetType().InvokeMember( "_shutDownStack", BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.GetField, null, runtime, null); 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);}
以上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。
