如何以编程方式查找调用Application_End()的原因？

Question

Application_End() 在我的应用程序池停止时调用,这可能由于多种原因而发生,包括自动池回收或从中提供应用程序的文件夹中的更改.

调用堆栈通常如下所示:

my Application_End(Object sender, EventArgs e)
at System.RuntimeMethodHandle._InvokeMethodFast(IRuntimeMethodInfo method, Object target, Object[] arguments, SignatureStruct& sig, MethodAttributes methodAttributes, RuntimeType typeOwner)
at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks)
at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)
at System.Reflection.MethodBase.Invoke(Object obj, Object[] parameters)
at System.Web.HttpApplication.InvokeMethodWithAssert(MethodInfo method, Int32 paramCount, Object eventSource, EventArgs eventArgs)
at System.Web.HttpApplication.ProcessSpecialRequest(HttpContext context, MethodInfo method, Int32 paramCount, Object eventSource, EventArgs eventArgs, HttpSessionState session)
at System.Web.HttpApplicationFactory.Dispose()
at System.Web.HttpRuntime.Dispose()
at System.Web.HttpRuntime.ReleaseResourcesAndUnloadAppDomain(Object state)
at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean ignoreSyncCtx)
at System.Threading.QueueUserWorkItemCallback.System.Threading.IThreadPoolWorkItem.ExecuteWorkItem()
at System.Threading.ThreadPoolWorkQueue.Dispatch()
at System.Threading._ThreadPoolWaitCallback.PerformWaitCallback()

这是完全没用的.

我如何以编程方式找到它被调用的原因？

Answer 1

有一个System.Web.Hosting.HostingEnvironment.ShutdownReason属性指示应用程序被终止的原因.它的价值可以从里面检索Application_End().
