在MVC中使用单选按钮显示动态字段

public class User
{
    public string Name { get; set; }
    public string Gender { get; set; }
}

@model User

@using (Html.BeginForm("SaveUser", "Home", FormMethod.Post))
{
    <div>
        @Html.LabelFor(model => model.Name)
        @Html.TextBoxFor(model => model.Name)
    </div>
    
    <div>
        @Html.LabelFor(model => model.Gender)
        @Html.RadioButtonFor(model => model.Gender, "male") Male
        @Html.RadioButtonFor(model => model.Gender, "female") Female
    </div>
    
    <input type="submit" value="Save" />
}

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new User());
    }
    
    [HttpPost]
    public ActionResult SaveUser(User user)
    {
        // 处理表单提交的数据，例如保存到数据库
        // ...
        
        return RedirectToAction("Index");
    }
}
