ASP.NET MVC Adding Attribute "data-message" to Html.TextBoxFor

提问by Ian Vink

Using MVC 4 I create a text box for a model property with the "data-message" attribute:

使用 MVC 4，我为具有“data-message”属性的模型属性创建了一个文本框：

@Html.TextBoxFor(o => o.TradeOrder.Symbol, new {data-message="Required"})

However, I get the following error:

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.

匿名类型成员声明符无效。匿名类型成员必须使用成员赋值、简单名称或成员访问进行声明。

Use _:

使用_：

@Html.TextBoxFor(o => o.TradeOrder.Symbol, new {data_message="Required"})

The TextBoxFor helper will know what to do and replace it with -when generating the markup.

TextBoxFor 助手将知道要做什么并-在生成标记时将其替换。
