关于编码规范

 

public static MvcForm BeginRouteForm(this AjaxHelper ajaxHelper, string routeName, RouteValueDictionary routeValues, AjaxOptions ajaxOptions)
        {
            return BeginRouteForm(ajaxHelper, routeName, routeValues, ajaxOptions, null /* htmlAttributes */);
        }

System.Web.Mvc中AjaxExtensions.cs

注释是否可替换成Named Arguments

public static MvcForm BeginRouteForm(this AjaxHelper ajaxHelper, string routeName, RouteValueDictionary routeValues, AjaxOptions ajaxOptions)
        {
            return BeginRouteForm(ajaxHelper, routeName, routeValues, ajaxOptions, htmlAttributes: null );
        }
