    string actionName = (string) filterContext.RouteData.Values["action"];

    viewData.Model = new HandleErrorInfo(filterContext.Exception, controllerName, actionName);
    filterContext.Result = new ViewResult { ViewName = this.View, MasterName = this.Master, ViewData = viewData, TempData = filterContext.Controller.TempData };
    filterContext.ExceptionHandled = true;
    filterContext.HttpContext.Response.Clear();
    //filterContext.HttpContext.Response.StatusCode = 500;
    filterContext.HttpContext.Response.TrySkipIisCustomErrors = true;

"area" -> "Public"
"controller", "MyError"
"action" -> "Error";

在设置filterContext.Result之前，请尝试添加以下行：

filterContext.RouteData.DataTokens["area"] = "Public";
filterContext.RouteData.Values["controller"] = "MyError";
