c# - MVC3 按属性名称本地化显示名称属性

Question

我最近学习了如何使用以下文章为我的模型属性创建本地化显示名称:Simplified localization for DataAnnotations

我现在正试图通过从构造函数中删除参数来进一步插入它。意思不是拥有这个

public class User
{
    [Required]
    [LocalizedDisplayNameAttribute("User_Id")]
    public int Id { get; set; }

    [Required]
    [StringLength(40)]
    [LocalizedDisplayNameAttribute("User_FirstName")]
    public string FirstName { get; set; }

    [Required]
    [StringLength(40)]
    [LocalizedDisplayNameAttribute("User_LastName")]
    public string LastName { get; set; }
}

我想要这个

public class User
{
    [Required]
    [LocalizedDisplayNameAttribute]
    public int Id { get; set; }

    [Required]
    [StringLength(40)]
    [LocalizedDisplayNameAttribute]
    public string FirstName { get; set; }

    [Required]
    [StringLength(40)]
    [LocalizedDisplayNameAttribute]
    public string LastName { get; set; }
}

现在的问题是我如何让这个类:

public class LocalizedDisplayNameAttribute : DisplayNameAttribute
{
    private PropertyInfo _nameProperty;
    private Type _resourceType;

    public LocalizedDisplayNameAttribute(string className, string propertyName)
        : base(className + (propertyName == null ? "_Class" : ("_" + propertyName)))
    {

    }

    public override string DisplayName
    {
        get
        {
            return LanguageService.Instance.Translate(base.DisplayName) ?? "**" + base.DisplayName + "**";
        }
    }
}

无需在构造函数中指定即可知道我的属性名称。

它对我来说很好。

[DataType(DataType.EmailAddress, ErrorMessageResourceName = "ThisFieldIsRequired", ErrorMessageResourceType = typeof(Resource))]
        [Required(ErrorMessageResourceName = "ThisFieldIsRequired", ErrorMessageResourceType = typeof(Resource))]
        [RegularExpression(@"^[\w-]+(\.[\w-]+)*@([a-z0-9-]+(\.[a-z0-9-]+)*?\.[a-z]{2,6}|(\d{1,3}\.){3}\d{1,3})(:\d{4})?$", ErrorMessageResourceName = "ThisFieldIsRequired", ErrorMessageResourceType = typeof(Resource))]
        [Display(Name = "EmailID", ResourceType = typeof(Resource))]
        public string EmailID { get; set; }
