MVC:你如何给视图模型一个列表，并在.cshtml上正确地输出它

我所做的是搜索Activedirectory用户，给定的值是名称。然后，我创建一个包含值名称，电子邮件和描述的视图模型。然后，我在索引上将其显示为 .cshtml。

问题是我制作它的方式，它只通过它找到的第一个用户发送 - （如果我从多个 Andrew 中搜索 Andrew，它会找到所有用户，但返回第一个。

我想将它们添加到列表中，然后几乎做同样的事情，但当然在 .cshtml 上迭代列表并显示结果。

这是HomeController.cs代码 -

public ActionResult Index(IndexViewModel profile)
{
    if (ModelState.IsValid)
    {
        //List<Principal> users = new List<Principal>();
        using (PrincipalContext ctx = new PrincipalContext(ContextType.Domain))
        {
            UserPrincipal qbeUser = new UserPrincipal(ctx);
            qbeUser.DisplayName = profile.Name + "*";
            using (PrincipalSearcher srch = new PrincipalSearcher(qbeUser))
            {
                if(!(srch.FindAll().Count() < 0))
                {
                    foreach(var found in srch.FindAll())
                    {
                        //users.Add(found);
                        IndexViewModel returnmodel = new IndexViewModel(found);
                        return View(returnmodel);
                    }
                }                       
            }
        }
    }
    return View(profile);
}

其中要看的一点是

foreach(var found in srch.FindAll())
{
    //users.Add(found);
    IndexViewModel returnmodel = new IndexViewModel(found);                               
    return View(returnmodel);
}

下面是 IndexViewModel 的代码.cs#

public class IndexViewModel
{
    public IndexViewModel(Principal found)
    {
        Name = found.DisplayName;
        Email = found.UserPrincipalName;
        Description = found.Description;
    }
    [Required(ErrorMessage = "Please enter a name")]
    [Display(Name = "Persons Name")]
    public string Name { get; set; }
    public string Email { get; set; }
    public string Description { get; set; }
}

这是Index.cshtml

/这只是创建输入框、验证文本和提交按钮。

<div id="content">
@Html.ValidationSummary(true)
@using (Html.BeginForm("Index", "Home"))
{
    <fieldset>
        <div class="form-group col-md-12">
            @Html.LabelFor(model => model.Name, new { @class = "control-label col-md-2" })
            <div class="col-md-4">
                @Html.EditorFor(modelItem => Model.Name, new { htmlAttributes = new { @class = "form-control", @style = "width:280px" }, })
                @Html.ValidationMessageFor(x => x.Name)
            </div>
            <div class="col-md-2">
                <input type="submit" class="btn btn-default" value="Search">
            </div>
            <div class="col-md-3">
            </div>
        </div>
    </fieldset>
}
<br>
</div>

这里显示找到的单个结果/
