Question

我正在构建一个从数据库中的视图返回信息的函数。

我的控制器看起来像是

         [HttpPost]
    public ActionResult StudentsLookup(string Firstname, string Lastname)
    {
        //checks for vaild name
        var nameCount = db.v_Directory.Where(name => name.LAST_NAME == Lastname).Count();

        //searches by lastname
        if (string.IsNullOrEmpty(Firstname) && nameCount > 0)

        {
            object c = db.v_Directory.Where(name => name.LAST_NAME == Lastname).ToList();
            return View("StudentsLookup", c);
        }

        //searches by fullname
        if (!string.IsNullOrEmpty(Firstname) && nameCount > 0)
        {
            object l = db.v_Directory.Where(name => name.LAST_NAME == Lastname && name.FIRST_NAME == Firstname).ToList();
            return View("StudentLookup", l);

        }
        else
        {
            ViewBag.Message = "Invalid Search";
            return View("Index");
        }
    }

仅搜索姓氏的函数返回有效视图，搜索名字和姓氏将返回异常。我是新编码而且很困惑。在两种情况下，调试显示通过模型传输的数据。

View看起来像这样：

@{
    ViewBag.Title = "StudentsLookup";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

<h2>StudentsLookup</h2>

@{ 
        if (Model != null)
        {
            <h1>Possible Matches</h1>
            <table>
                <tr>
                    <th> STUDENT_ID </th>
                    <th> FirstName </th> 
                    <th> LastName </th>
                    <th> USER_NAME </th>
                </tr>
                @foreach (var person in Model)
                {
                    <tr>
                        <td>@person.STUDENT_ID</td>
                        <td>@person.FIRST_NAME </td>
                        <td>@person.LAST_NAME </td>
                        <td>@person.USER_NAME</td>
                    </tr>
                }
            </table>
        }
}

我收到错误，InvalidOperationException：找不到视图'StudentLookup'或其主人，或者没有视图引擎支持搜索的位置。搜索了以下位置： Message ='bool'不包含'STUDENT_ID'的定义

非常感谢任何帮助。
