Asp.net mvc Asp.NETMVC:处理错误视图中抛出的错误

我在MVC（4）中设置了错误处理，它工作得很好。我已经在global.asax中注册了HandleErrorAttribute，并在web.config中设置了适当的配置。

---

但是，如果我重定向到错误视图，并且错误视图本身抛出错误，我将被重定向回错误页面-无休止。错误发生在应用程序外部管理的布局和布局中。如果布局有错误，我会被套住。我怎样才能防止这种情况？我应该使用哪种类型的错误处理回退？使用不同的布局不是一个选项。

我是这样做的。试一试：

protected void Application_Error(object sender, EventArgs e)
{                        
    //Retrieving the last server error
    var exception = Server.GetLastError();    

    //Erases any buffered HTML output
    Response.Clear();

    //Declare the exception
    var httpException = exception as HttpException;

    var routeData = new RouteData();
    routeData.Values.Add("controller", "Error"); //Adding a reference to the error controller

    if (httpException == null)
    {
        routeData.Values.Add("action", "ServerError"); //Non HTTP related error handling
    }
    else //It's an Http Exception, Let's handle it.
    {
        switch (httpException.GetHttpCode())
        {
            //these are special views to handle each error
            case 401:
            case 403:
                //Forbidden page.
                routeData.Values.Add("action", "Forbidden");
                break;
            case 404:
                //Page not found.
                routeData.Values.Add("action", "NotFound");
                break;       
            case 500:
                routeData.Values.Add("action", "ServerError");
                break;
            default:
                routeData.Values.Add("action", "Index");
                break;
        }
    }

    //Pass exception details to the target error View.
    routeData.Values.Add("message", exception);

    //Clear the error on server.
    Server.ClearError();

    //Avoid IIS7 getting in the middle
    Response.TrySkipIisCustomErrors = true;

    // Call target Controller and pass the routeData.
    IController errorController = new ErrorController();
    errorController.Execute(new RequestContext(
         new HttpContextWrapper(Context), routeData));
}

当视图中出现错误时，您能否调试并验证

Application\u error

是否在全局中命中。asax？当视图中出现错误时，您能否调试并验证

Response.TrySkipIisCustomErrors=true修复。感谢您的回复，艾哈迈德！如果您的ServerError操作引发异常，会发生什么情况？对Graham说：我也遇到过这种情况：）我花了一个下午找出了一个bug，直到我发现
