网络配置：

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

过滤器配置.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在我的自定义错误视图中查看异常：

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它会显示在视图上，而不是我故意从 Index 操作中抛出的异常。

这是错误视图中出现的内容：

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

Controller:

有人可以告诉我为什么OperationInvalidException我的投掷后会发生Exception吗？我错过了什么吗？
