Question

我正在

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)

和内部异常是

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

我在许多其他问题中看到了类似的东西，通常会有一些或多或少的明确信息，可以从中推断出问题原因。

就我而言，只有Exception of type 'System.Web.HttpUnhandledException' was thrown.

如何从HttpUnhandledException中提取其他信息以尝试查找抛出原因？

Answer 1

原来我的代码没有提取InnerException的{{1}}。我抓住了IIS源代码（是的，可以正式下载），发现HttpUnhandledException抛出System.Web.UI.Page.HandleError(Exception e)并将HttpUnhandledException传递给它的构造函数。我希望e的{{1}}变得有用。

Answer 2

您可以将此代码添加到错误消息中：

errorMessage += "\n\n Inner Exception:\n\n" +ex.InnerException;

InnerException属性将为您提供有关错误的更多详细信息。

我希望它有所帮助！

Answer 3

您是否在服务器上部署了您的网站，如果是，请转到

C：\ WINDOWS \ Microsoft.NET \框架 \ v2.0.50727 \ Temporary ASP.NET Files并删除您的站点文件夹。然后重启IIS。检查申请。

我怎么找到为什么我得到“类型的异常'System.Web.HttpUnhandledException'被抛出”？
