ASP.NET MVC，添加单个属性

Question

对于attribute =“value”，我使用

@Html.TextBoxFor(x => x.Email, new { type = "email", @class = "form-control",
 placeholder="Email address" })

它给了我：

<input class="form-control" id="Email" name="Email" placeholder="Email address"
 type="email" value="" />

如何添加单个属性，因此我需要自定义和自动对焦：

<input class="form-control" id="Email" name="Email" placeholder="Email address" 
type="email" value=""  required autofocus />

谢谢！

如果您使用string.Empty，您将在生成的html中获得一个空属性

@Html.TextBoxFor(x => x.Email, new { type = "email", @class = "form-control",
placeholder = "Email address", required = string.Empty, autofocus = string.Empty })
