@Html.TextBoxFor(o => o.TradeOrder.Symbol,new {data-message="required"})
但是，我收到以下错误：
Invalid anonymous type member declarator. Anonymous type members must be declared with a member assignment,simple name or member access.
@Html.TextBoxFor(o => o.TradeOrder.Symbol,new {data_message="required"})
TextBoxFor帮助器将知道该怎么做，并在生成标记时替换它。
