我如何记录未处理的ASP.NET MVC异常？ [英] How do I log unhandled exceptions in ASP.NET MVC?

问题描述

下面就是我想要做我的Global.asax.vb：

Here's what I'm trying to do in my Global.asax.vb:

Public Class MvcApplication
    Inherits System.Web.HttpApplication

    Shared Sub RegisterRoutes(ByVal routes As RouteCollection)
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}")
        routes.MapRoute( _
            "Error", _
            "error.html", _
            New With {.controller = "Error", _
                      .action = "FriendlyError"} _
        )
        ...
        'other routes go here'
        ...
    End Sub

    Sub Application_Start()
        RegisterRoutes(RouteTable.Routes)
    End Sub

    Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
        ...
        'code here logs the unhandled exception and sends an email alert'
        ...
        Server.Transfer("http://www.example.com/error.html")
    End Sub

End Class

但是，Server.Transfer的失败：

But that Server.Transfer fails:

无效的路径子请求 http://www.example.com/ 的error.html。虚拟路径的预期。

Invalid path for child request 'http://www.example.com/error.html'. A virtual path is expected.

我该如何解决这个问题？或者，有什么更好的方法为我做到这一点？

How do I fix this? Or, what's a better way for me to do this?

推荐答案

我刚刚发现这对斯科特Hanselman的博客<一href="http://www.hanselman.com/blog/ELMAHErrorLoggingModulesAndHandlersForASPNETAndMVCToo.aspx">here所谓 ELMAH 这是一个错误记录器/处理器，您可以使用，而无需改变你的code。你可能想看看它，因为它似乎与MVC很好地工作。

I just found this on Scott Hanselman's blog here called ELMAH which is an Error Logger/Handler that you can use without having to change your code. You might want to look into it, since it seems to work nicely with MVC.
