C# 不是我的日常语言，所以对它很陌生

这是我的模特

public class SpecialtyListsModels
{
    public Dictionary<int, dynamic> specialties = new Dictionary<int, dynamic>();

    public Dictionary<int, dynamic> SpecialtyLists()
    {
        specialties.Add(1, new {name = "Varun", age = "11"} );
        specialties.Add(2, new {name = "Khushi", age = "12"} );

        return (specialties);
    }
}

这是我的课

public class SignupController : Controller
{
    public ActionResult Index()
    {
        PFSignup.Models.SpecialtyListsModels objSpecialtyList = new PFSignup.Models.SpecialtyListsModels();

        Dictionary<int, dynamic> specialtyLists = objSpecialtyList.SpecialtyLists();

        return View();
    }

    [HttpPost]
    public ActionResult Create(SignupModels signup)
    {
        return View(signup);
    }
}

这是我的视图，我想在其中添加所有专业的下拉列表

<body>
<div>
    @using (Html.BeginForm("Create", "Signup"))
    {
        <label for="first_name">First Name:</label>
        <input type="text" name="first_name" id="first_name" value="" />

        <br />

        <label for="last_name">Last Name:</label>
        <input type="text" name="last_name" id="last_name" value ="" />

        @Html.DropDownList("specialty_list", new SelectList(SpecialtyListModels, ) 

        <input type="submit" name="submit" value="Submit" />
     }
</div>

有人可以帮我解决下拉列表代码吗，我需要在视图顶部添加列表吗？
