Asp.net mvc 4 MVC5实体框架数据库优先使用字符串主键

我创建了一个数据库第一实体框架MVC5应用程序。这个表有一个字符串主键。我使用脚手架创建了控制器。我的控制器/索引工作正常，但详细信息、编辑和创建不起作用。如果我使用int主键，所有CRUD都可以正常工作。 EF不支持字符串主键

这是我的Index.cshtml

@foreach (var item in Model) {
<tr>

    <td>
        @Html.DisplayFor(modelItem => item.Owner)
    </td>

    <td>
        @Html.DisplayFor(modelItem => item.Address)
    </td>

    <td>
        @Html.ActionLink("Edit", "Edit", new { id=item.Property_Ref }) |
        @Html.ActionLink("Details", "Details", new { id=item.Property_Ref }) |
        @Html.ActionLink("Delete", "Delete", new { id=item.Property_Ref })
    </td>

</tr>
}

所有这些代码首先由MVC5数据库生成，并使用脚手架作为控制器

索引工作正常，列出所有记录， 单击“详细信息”时，在“/”应用程序中出现一个错误。

http://localhost:51356/Property/Details/2

-这里2是一个字符串主键！[在此处输入图像描述][1]

非常感谢

正如Jhoon Bey所说，在从数据库构建EF数据模型之前，请确保该表已将“Property_Ref”标记为主键。FYR，工作代码：

表格：

private TestDbEntities1 db = new TestDbEntities1();

    // GET: /Person/
    public ActionResult Index()
    {
        return View(db.People.ToList());
    }

    // GET: /Person/Details/5
    public ActionResult Details(string id)
    {
        if (id == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }
        Person person = db.People.Find(id);
        if (person == null)
        {
            return HttpNotFound();
        }
        return View(person);
    }

    // GET: /Person/Create
    public ActionResult Create()
    {
        return View();
    }

<h2>Index</h2>
<p>
@Html.ActionLink("Create New", "Create")
</p>
<table class="table">
<tr>
    <th>
        @Html.DisplayNameFor(model => model.Name)
    </th>
    <th></th>
</tr>

@foreach (var item in Model) {
<tr>
    <td>
        @Html.DisplayFor(modelItem => item.Name)
    </td>
    <td>
        @Html.ActionLink("Edit", "Edit", new { id=item.Property_ref }) |
        @Html.ActionLink("Details", "Details", new { id=item.Property_ref }) |
        @Html.ActionLink("Delete", "Delete", new { id=item.Property_ref })
    </td>
</tr>

EF型号：

private TestDbEntities1 db = new TestDbEntities1();

    // GET: /Person/
    public ActionResult Index()
    {
        return View(db.People.ToList());
    }

    // GET: /Person/Details/5
    public ActionResult Details(string id)
    {
        if (id == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }
        Person person = db.People.Find(id);
        if (person == null)
        {
            return HttpNotFound();
        }
        return View(person);
    }

    // GET: /Person/Create
    public ActionResult Create()
    {
        return View();
    }

<h2>Index</h2>
<p>
@Html.ActionLink("Create New", "Create")
</p>
<table class="table">
<tr>
    <th>
        @Html.DisplayNameFor(model => model.Name)
    </th>
    <th></th>
</tr>

@foreach (var item in Model) {
<tr>
    <td>
        @Html.DisplayFor(modelItem => item.Name)
    </td>
    <td>
        @Html.ActionLink("Edit", "Edit", new { id=item.Property_ref }) |
        @Html.ActionLink("Details", "Details", new { id=item.Property_ref }) |
        @Html.ActionLink("Delete", "Delete", new { id=item.Property_ref })
    </td>
</tr>

控制器：

private TestDbEntities1 db = new TestDbEntities1();

    // GET: /Person/
    public ActionResult Index()
    {
        return View(db.People.ToList());
    }

    // GET: /Person/Details/5
    public ActionResult Details(string id)
    {
        if (id == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }
        Person person = db.People.Find(id);
        if (person == null)
        {
            return HttpNotFound();
        }
        return View(person);
    }

    // GET: /Person/Create
    public ActionResult Create()
    {
        return View();
    }

<h2>Index</h2>
<p>
@Html.ActionLink("Create New", "Create")
</p>
<table class="table">
<tr>
    <th>
        @Html.DisplayNameFor(model => model.Name)
    </th>
    <th></th>
</tr>

@foreach (var item in Model) {
<tr>
    <td>
        @Html.DisplayFor(modelItem => item.Name)
    </td>
    <td>
        @Html.ActionLink("Edit", "Edit", new { id=item.Property_ref }) |
        @Html.ActionLink("Details", "Details", new { id=item.Property_ref }) |
        @Html.ActionLink("Delete", "Delete", new { id=item.Property_ref })
    </td>
</tr>

索引：

private TestDbEntities1 db = new TestDbEntities1();

    // GET: /Person/
    public ActionResult Index()
    {
        return View(db.People.ToList());
    }

    // GET: /Person/Details/5
    public ActionResult Details(string id)
    {
        if (id == null)
        {
            return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
        }
        Person person = db.People.Find(id);
        if (person == null)
        {
            return HttpNotFound();
        }
        return View(person);
    }

    // GET: /Person/Create
    public ActionResult Create()
    {
        return View();
    }

<h2>Index</h2>
<p>
@Html.ActionLink("Create New", "Create")
</p>
<table class="table">
<tr>
    <th>
        @Html.DisplayNameFor(model => model.Name)
    </th>
    <th></th>
</tr>

@foreach (var item in Model) {
<tr>
    <td>
        @Html.DisplayFor(modelItem => item.Name)
    </td>
    <td>
        @Html.ActionLink("Edit", "Edit", new { id=item.Property_ref }) |
        @Html.ActionLink("Details", "Details", new { id=item.Property_ref }) |
        @Html.ActionLink("Delete", "Delete", new { id=item.Property_ref })
    </td>
</tr>

索引

@ActionLink（“新建”、“创建”）

@DisplayNameFor（model=>model.Name）
@foreach（模型中的var项目）{
@DisplayFor（modelItem=>item.Name）
@ActionLink（“编辑”，“编辑”，新的{id=item.Property\u ref}）|
@ActionLink（“详细信息”，“详细信息”，新的{id=item.Property\u ref}）|
@ActionLink（“删除”，“删除”，新的{id=item.Property\u ref}）

}

能否添加更详细的例外情况？这并没有告诉我们任何事情。您是否将“Property\u Ref”设置为数据库中的主键？
