Asp.net mvc 3 MVC3下拉列表值未在编辑器模板内填充

我有一个带有下拉菜单的编辑器模板：

 @Html.DropDownListFor(m => m.AdmissionState, new List<SelectListItem>()
                                                   {
                                                       new SelectListItem()
                                                           {
                                                               Text = "1",
                                                               Value = "1"
                                                           },
                                                       new SelectListItem()
                                                           {
                                                               Text = "2",
                                                               Value = "2"
                                                           },
                                                       new SelectListItem()
                                                           {
                                                               Text = "3",
                                                               Value = "3"
                                                           },                   
                                                   }, "- Select -")

在控制器中，我有以下代码：

profile.Licenses.Add(new AttorneyLicenseModel()
        {
            AdmissionDate = "06/14/2012",
            AdmissionState = "2",
            AdmissionNumber = "asd",
        });
        profile.Licenses.Add(new AttorneyLicenseModel()
        {
            AdmissionDate = "07/16/2012",
            AdmissionState = "5",
            AdmissionNumber = "qwe",
        });

对于每个许可证，我都会看到包含从模型填充的数据的字段，但对于下拉列表，则不会看到这些字段-默认值已选中。我做错了什么？当然，带值的代码非常简单

请尝试以下操作：

@Html.DropDownListFor(
    m => m.AdmissionState, 
    new SelectList(
        new[] 
        {
            new { Value = "1", Text = "1" },
            new { Value = "2", Text = "2" },
            new { Value = "3", Text = "3" },
        }, 
        "Value", 
        "Text", 
        Model.AdmissionState
    ),
    "- Select -"
)

如果您有兴趣了解为什么我的代码有效而您的代码无效，您可以阅读我昨天对类似问题提供的以下答案：

@Html.DropDownListFor(
    m => m.AdmissionState, 
    new SelectList(
        new[] 
        {
            new { Value = "1", Text = "1" },
            new { Value = "2", Text = "2" },
            new { Value = "3", Text = "3" },
        }, 
        "Value", 
        "Text", 
        Model.AdmissionState
    ),
    "- Select -"
)
