asp.net-mvc-3 – 与ASP.NET MVC 3中的视图页面不同的模型的窗体

class Results
{
     ... // some results data to display
}

class EmailSignup
{
    public virtual int Id { get; set; }

    [Required(ErrorMessage = "Please enter your email.")]
    [DataType(DataType.EmailAddress)]
    [RegularExpression(@"^(([A-Za-z0-9]+_+)|([A-Za-z0-9]+-+)|([A-Za-z0-9]+.+)|([A-Za-z0-9]+++))*[A-Za-z0-9]+@((w+-+)|(w+.))*w{1,63}.[a-zA-Z]{2,6}$",ErrorMessage = "Please enter a valid email address.")]
    public virtual string Email { get; set; }
}

Results.cshtml

@model MyApp.Results
[display results]
...
@using (Html.BeginForm("SubmitEmail","AnalysisResults",FormMethod.Post))
{
     <fieldset>
     @Html.TextBoxFor( model => model.???? )
     </fieldset>
}

我想要用户提交的类型是EmailSignup，而不是结果。
