C# 如何在自定义HandleErrorAttribute中获取http状态代码

我正在使用一个自定义HandleErrorAttribute，它通过在过滤器中注册而全局应用。问题是，我无法捕获正确的http错误代码。每次该属性中有200个代码

public class HandleAndLogErrorAttribute : HandleErrorAttribute
{
    public override void OnException(ExceptionContext filterContext)
    {
        if (filterContext.ExceptionHandled || !filterContext.HttpContext.IsCustomErrorEnabled)
            return;
        var statusCode = filterContext.HttpContext.Response.StatusCode; //always 200
        LogManager.Error(filterContext.Exception);

        filterContext.Result = CreateActionResult(filterContext, statusCode);
        filterContext.ExceptionHandled = true;
        filterContext.HttpContext.Response.Clear();
        filterContext.HttpContext.Response.StatusCode = statusCode;
        //filterContext.HttpContext.Response.TrySkipIisCustomErrors = true;
    }

    protected virtual ActionResult CreateActionResult(ExceptionContext filterContext, int statusCode)
    {
        var ctx = new ControllerContext(filterContext.RequestContext, filterContext.Controller);
        var statusCodeName = ((HttpStatusCode)statusCode).ToString();
        var viewName = "~/Views/Shared/Error.cshtml";
        var controllerName = (string)filterContext.RouteData.Values["controller"];
        var actionName = (string)filterContext.RouteData.Values["action"];
        var model = new HandleErrorInfo(filterContext.Exception, controllerName, actionName);
        var result = new ViewResult
        {
            ViewName = viewName,
            ViewData = new ViewDataDictionary<HandleErrorInfo>(model),
        };
        result.ViewBag.StatusCode = statusCode;
        return result;
    }
}

通过查看的源代码，您似乎可以使用以下代码获得状态代码

var statusCode = new HttpException(null, filterContext.Exception).GetHttpCode();

是否可以尝试通过新的HttpExceptionnull、filterContext.Exception.GetHttpCode获取状态代码
