LabelFor不显示价值？

Question

I'm trying to just display a value in my Razor code. 我试图在我的Razor代码中显示一个值。 I've tried both DisplayFor and LabelFor. 我已经尝试过DisplayFor和LabelFor。 If I use DisplayFor then my value shows up but my CSS doesn't get applied. 如果我使用DisplayFor，则会显示我的值，但不会应用CSS。 If I use LabelFor then it's the opposite, my CSS is applied but the text only displays as "EmployeeId". 如果我使用LabelFor，则相反，将应用我的CSS，但文本仅显示为“ EmployeeId”。 I've confirmed that my ViewModel has a value populated for the EmployeeId prior to going to View. 我已经确认，在进入View之前，我的ViewModel具有为EmployeeId填充的值。

This is what I've tried: 这是我尝试过的：

<div class="row voffset2">
    <div class="col-md-12">
        Employee ID: @Html.LabelFor(m => m.EmployeeId, new { @class = "control-label label-value" })
    </div>
</div>

<div class="row voffset2">
    <div class="col-md-12">
        Employee ID: @Html.DisplayFor(m => m.EmployeeId, new { @class = "control-label label-value" })
    </div>
</div>

Answer 1

first of all DisplayFor does not have an overload of htmlAttributes so new { @class = "control-label label-value" } wont work and secondly LabelFor does not display value of the property it will just display the name of the property so you can do it like this 首先DisplayFor没有htmlAttributes的重载，所以new { @class = "control-label label-value" }不起作用，其次LabelFor不显示属性的值，它将仅显示属性的名称，因此您可以像这样做

<div class="row voffset2">
    <div class="col-md-12">
        Employee ID: <span class"ontrol-label label-value">@Html.DisplayFor(m => m.EmployeeId)</span>
    </div>
</div>

This will work: 这将起作用：

public class LabelViewModel
{
    [Display(Name = "Employee\nId")]
    public int EmployeeId { get; set; }

    //display for is for iterating over a collection
    public IList<string> Employees { get; set; }
}

public class HomeController : Controller
{
    public ActionResult Index54()
    {
        //display for is for iterating over a collection
        LabelViewModel labelViewModel = new LabelViewModel();
        labelViewModel.Employees = new List<string>();
        labelViewModel.Employees.Add("emp1");
        labelViewModel.Employees.Add("emp2");
        return View(labelViewModel);
    }

View: 视图：

@model Testy20161006.Controllers.LabelViewModel
@{
    Layout = null;
}
