Can I change the html name generated by Html.DropDownListFor?

Question

IDI am using the following code to create a drop down list:

 @for (var index = 0; index < Model.AdminSummaries.Count(); index++) 
            { 
            &

My solution to this issue is to replace the id and name after DropDownListFor() with a html helper extension method.

        public static MvcHtmlString ReplaceIdAndName(this MvcHtmlString htmlSource, string name)
    {
        MvcHtmlString result;
        if (name == null)
            result = htmlSource;
        else
        {
            string id = name.Replace("[", "_").Replace("]", "_").Replace(".", "_");  // HTML ids cannot have []. so MVC convention replaces with _
            XDocument html = XDocument.Parse(htmlSource.ToHtmlString());
            html.Elements().Select(e => e.Attribute("id")).FirstOrDefault().SetValue(id);
            html.Elements().Select(e => e.Attribute("name")).FirstOrDefault().SetValue(name);
            result = MvcHtmlString.Create(html.ToString());
        }
        return result;
    }


DropDownListFor(...).ReplaceIdAndName("myclass[1].myprop");
