Question

我需要在视图中通过逗号显示学生姓名+姓氏。

public class Student
{
    public int ID { get; set; }
    public string LastName { get; set; }
    public string FirstMidName { get; set; }
    public DateTime EnrollmentDate { get; set; }

    public virtual ICollection<Enrollment> Enrollments { get; set; }
}

我的观点看起来像，我知道hpw要添加一个列，但我不知道如何向学生展示姓名+ LastName

<table class="table">
    <tr>
        <th>
            @Html.ActionLink("Last Name", "Index", new { sortOrder = ViewBag.NameSortParm })
        </th>
        <th>
            First Name
        </th>
        <th>
            @Html.ActionLink("Enrollment Date", "Index", new { sortOrder = ViewBag.DateSortParm })
        </th>
        <th></th>
    </tr>

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

Answer 1

您可以尝试添加部分类以将FirstName + Surname显示为Fullname ...不确定这是否有帮助

    public partial class Student
{
    public string FullName
    {
        get
        {
            return string.Join(" ", FirstMidName, LastName);
        }
    }

}

Answer 2

你需要这样的东西

控制器：

public ViewResult Registrants() {
IList<CompetitionNames> names = new List<CompetitionNames>();
foreach (Competition comp in repository.Competitions) {
names.Add(new CompetitionNames {
EventName = comp.Name,
RegistrantNames = comp.Registrations.Select(e => e.Name).Distinct()
});
}
return View(names);

查看：

@foreach (var comp in Model) {
<tr>
<td>@comp.EventName</td>
<td>@string.Join(", ", comp.RegistrantNames)</td>
<td>@comp.RegistrantNames.Count()</td>
</tr>
}

我在Context BOOK的685页的Applied ASP.NET 4中看到了这一点
