当我使用 DataAnnotations 和 DisplayName 时 LabelFor 不起作用 - ASP.NET MVC

Question

I have a folder called "ModelMetaData.cs" where I have a class called "InspeccioModelMetaData.cs" with these code:

[DisplayName("Id")]
public string IdInspeccio { get; set; }
[DisplayName("Data de caducitat")]
public DateTime DataCaducitat { get; set; }

And the Model have these code:

[MetadataType(typeof(InspeccioModelMetaData))]
public partial class Inspeccio
{

...

public System.DateTime DataCaducitat { get; set; }

...

In the view when I use @Html.DisplayNameFor it works but when I use

@Html.LabelFor(model => model.DataCaducitat, htmlAttributes: new { @class = "control-label col-md-2" })

it doesn't.

I have searched the solution by googling but nothing works for me...

Can someone helps me please?

Thanks!

Make sure that these metadata classes are in the same namespace as the model.
