c# - 我如何找到为什么 "Exception of type ' System.Web.HttpUnhandledException'被抛出”的原因？

我越来越

System.Web.HttpException
Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerWrapper'.
Stack is
at System.Web.HttpServerUtility.ExecuteInternal(IHttpHandler handler, TextWriter writer, Boolean preserveForm, Boolean setPreviousPage, VirtualPath path, VirtualPath filePath, String physPath, Exception error, String queryStringOverride)

at System.Web.Mvc.ControllerActionInvoker.InvokeActionResultWithFilters(ControllerContext controllerContext, IList`1 filters, ActionResult actionResult)
at System.Web.Mvc.ControllerActionInvoker.InvokeAction(ControllerContext controllerContext, String actionName)

内部异常是

System.Web.HttpUnhandledException
Exception of type 'System.Web.HttpUnhandledException' was thrown.

我在许多其他问题中也看到过类似的内容，通常会有一些或多或少的清晰信息可以从中得出问题的原因。

就我而言，只有Exception of type 'System.Web.HttpUnhandledException' was thrown.
我如何从该HttpUnhandledException中提取其他信息以尝试查找为什么抛出该信息？

最佳答案

原来我的代码没有提取该InnerException的HttpUnhandledException。我捕获了IIS源(是的，可以正式下载它们)，发现System.Web.UI.Page.HandleError(Exception e)引发HttpUnhandledException并将e传递到其构造函数中。我希望InnerException的HttpUnhandledException变得有用。
