DisplayName 元数据未显示在视图中

Question

考虑到以下模型，我将如何在视图上显示正确的 DsiplayName。

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Project.Models.RegisterViewModel>" %>

<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
    <% using (Html.BeginForm())
       {%>
    <table>
        <tr>
            <td class="label">
                <%: Html.LabelFor(model => model.User.UserPrimaryEmail)%>
            </td>
            <td class="field">
                <%: Html.TextBoxFor(model => model.User.UserPrimaryEmail)%>
            </td>
            <td class="field-error">
                <div class="field-error-msg">
                    <%: Html.ValidationMessageFor(model => model.User.UserPrimaryEmail)%>
                </div>
            </td>
        </tr>
 </table>
</asp:Content>

public class RegisterViewModel
{
    public User User { get; set; }
}


[MetadataType(typeof(UserMetaData))]
public partial class User : UserBase
{
 //Inherits from Generated Class UserBase
 //to set default values here for the constructor

    // Not used except as a source of metadata
    public class UserMetaData
    {

        [Required]
        [DisplayName("Email Login")]
        [DataType(DataType.EmailAddress)]
        [Email(ErrorMessage = "Invalid Email")]
        public string UserPrimaryEmail { get; set; }


    }

}

表单不显示“Email Login”而是“UserPrimaryEmail”

Answer 1

您的视图被强类型化为 Project.Models.RegisterViewModel，但是您正在将数据注释添加到用户对象。

通常你会：

public class RegisterViewModel
{
    [Required]
    [DisplayName("Email Login")]
    [DataType(DataType.EmailAddress)]
    [Email(ErrorMessage = "Invalid Email")]
    public String Email { get; set; }

    .....
    other properties
}
