我怎么能一个类属性添加到由MVC的HTML辅助生成的HTML元素？ [英] How can I add a class attribute to an HTML element generated by MVC's HTML Helpers?

问题描述

ASP.NET MVC可以使用HTML辅助生成HTML元素，例如 @ Html.ActionLink（）， @ Html.BeginForm（）等。

ASP.NET MVC can generate HTML elements using HTML Helpers, for example @Html.ActionLink(), @Html.BeginForm() and so on.

我知道我可以指定形式通过创建匿名对象并通过该属性对象的（第四次在这种情况下） htmlAttributes 参数，其中指定 ID 的元素：

I know I can specify form attributes by creating an anonymous object and pass that object for the (fourth in this case) htmlAttributes parameter where specifying an id for the element:

Html.BeginForm("Foo", "Bar", FormMethod.Post, new { id = "MyForm"})

但对于类属性？显然，这并不工作：​​

But what about the class attribute? Obviously this does not work:

Html.BeginForm("Foo", "Bar", FormMethod.Post, new { class = "myclass"})

由于在请求我的看法，只是抛出随机语法错误，因为它需要别的东西遇到C＃关键字后类。

我也试过：

new { _class = "myclass"}

和

new { class_ = "myclass"}

但他们也没有工作，因为下划线得到由破折号取代。

我知道我可以只以及手工编写HTML元素或包裹一个＆LT内部的形式; DIV CLASS =MyClass的＆GT; ，但我ð仍然有兴趣知道它是如何应该做。

I know that I can just as well write the HTML elements by hand or wrap the form inside a <div class="myClass">, but I'd still be interested to know how it is supposed to be done.

推荐答案

为了创建具有的保留关键字作为其在C＃中的名称，可以prePEND与at符号属性名， @ ：

In order to create an anonymous type (or any type) with a property that has a reserved keyword as its name in C#, you can prepend the property name with an at sign, @:

Html.BeginForm("Foo", "Bar", FormMethod.Post, new { @class = "myclass"})

有关VB.NET <一个href=\"http://stackoverflow.com/questions/1444495/how-do-i-apply-a-css-class-to-html-actionlink-in-asp-net-mvc\">this语法将使用点来完成的，。，这在该语言是的 所有的匿名类型的：

For VB.NET this syntax would be accomplished using the dot, ., which in that language is default syntax for all anonymous types:

Html.BeginForm("Foo", "Bar", FormMethod.Post, new with { .class = "myclass" })
