MVC为什么新添加的列未命中显示数据

Question

我对MVC很陌生， 我首先使用数据库从本地sql server导入表。我使用entityFrameWork并保留所有默认功能。添加控制器和视图后。我回到我的sql server并添加另一个名为DateofBirth（datetime）的列。我去MVC， 我将DateofBirth放在模型和视图中（在创建视图中）。但是，数据会在所有＆＃39; 1/1/0001 12:00:00 AM +00：00＆＃39;而不是实际的数据。 可能的原因是什么？

人物模型：

    partial class Person
{
    public Person()
    {
        this.appts = new HashSet<appt>();
    }

    public int P_Id { get; set; }
    public string LastName { get; set; }
    public string FirstName { get; set; }
    public string Address { get; set; }
    public string City { get; set; }
    public DateTime DateofBirth { get; set; }

    public virtual ICollection<appt> appts { get; set; }
}

人物视图（索引）：

<table class="table">
<tr>
    <th>
        @Html.DisplayNameFor(model => model.P_Id)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.LastName)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.FirstName)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.Address)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.City)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.DateofBirth)
    </th>
    <th></th>
</tr>

          foreach (var item in Model) {
<tr>
    <td>
        @Html.DisplayFor(modelItem => item.P_Id)
    </td>
    <td>
        @Html.DisplayFor(modelItem => item.LastName)
    </td>
    <td>
        @Html.DisplayFor(modelItem => item.FirstName)
    </td>
    <td>
        @Html.DisplayFor(modelItem => item.Address)
    </td>
    <td>
        @Html.DisplayFor(modelItem => item.City)
    </td>
    <td>
        @Html.DisplayFor(modelItem => item.DateofBirth)
    </td>
    <td>
        @Html.ActionLink("Edit", "Edit", new { id=item.P_Id }) |
        @Html.ActionLink("Details", "Details", new { id=item.P_Id }) |
        @Html.ActionLink("Delete", "Delete", new { id=item.P_Id })
    </td>
          </tr>
              }

             </table>

控制器：
