asp.net-mvc – Asp.net MVC TextArea

<%=Html.TextAreaFor(
        m => m.Description,15,20,new RouteValueDictionary(new { @class = "someClass"}))%>

编辑：
这不会工作，据我所知

<%=Html.TextAreaFor(m => m.Description,new { cols = "20",rows = "15" })%>

因为这个：

private const int TextAreaRows = 2;
private const int TextAreaColumns = 20;

// ...





     public static string TextArea(
                this HtmlHelper htmlHelper,string name,IDictionary<string,object> htmlAttributes) {
            Dictionary<string,object> implicitAttributes = new Dictionary<string,object>();
            implicitAttributes.Add("rows",TextAreaRows.ToString(CultureInfo.InvariantCulture));
            implicitAttributes.Add("cols",TextAreaColumns.ToString(CultureInfo.InvariantCulture));
            return TextAreaHelper(htmlHelper,name,true /* useViewData */,null /* value */,implicitAttributes,null /* explicitParameters */,htmlAttributes);

}
