Question

的Web.config：

<customErrors mode="On" defaultRedirect="~/Error/">
    <error statusCode="404" redirect="~/Error/NotFound/"/>
    <error statusCode="403" redirect="~/Error/AccessDenied/"/>
<\customErrors>

FilterConfig.cs：

public static void RegisterGlobalFilters(GlobalFilterCollection filters) 
{
    filters.Add(new HandleErrorAttribute());
    filters.Add(new LtcAuthorizeAttribute());
}

我从控制器操作中抛出异常，以查看我的自定义错误视图中的异常：

public ActionResult Index(int id) 
{
    if (id == 69732645)
    {
        throw new Exception("This is just to test an Error.");
    }
    var repository = ClaimsHelper.GetRepository();
    var rfbEntity = repository.Single<RequestForBenefit>(x => x.RfbId == id);
    var rfbModel = Mapper.Map<RequestForBenefit, RequestForBenefitModel>(rfbEntity);
    ViewBag.EobList = Mapper.Map<ICollection<EpisodeOfBenefit>, ICollection<EpisodeOfBenefitModel>>(rfbModel.EpisodeOfBenefit);
    repository.Dispose();
    return View(rfbModel);
}

错误控制器和索引操作：

public class ErrorController : Controller 
{
    //
    // GET: /Error/
    public ActionResult Index()
    {
        return View("Error");
    }
}

当抛出异常时，会发生另一个异常，InvalidOperationException会显示在视图上，而不是我故意从我的Index操作中抛出的异常。

这是错误视图中的内容：

Controller: Error 
Action: Index 
Message: Object reference not set to an instance of an object. 

Controller:

at System.Web.Mvc.Async.AsyncControllerActionInvoker.<>c__DisplayClass25.<BeginInvokeAction>b__22(IAsyncResult asyncResult)

有人可以告诉我为什么在抛出OperationInvalidException之后发生了Exception？我错过了什么吗？

当我从控制器操作中抛出异常时，自定义错误处理结果与InvalidOperationException
