asp.net-mvc-3 – 如何从ModelMetadata检索GroupName数据注释

我试图在ASP.NET MVC3应用程序中访问此元数据,主要是为了创建属性网格.如果我的模型看起来像这样：

public class Customer
{
    [ReadOnly]
    public int Id { get;set; }

    [Display(Name = "Name",Description = "Customer's name",GroupName = "Basic")]
    [Required(ErrorMessage = "Please enter the customer's name")]
    [StringLength(255)]
    public string Name { get;set; }

    [Display(Name = "Email",Description = "Customer's primary email address",GroupName = "Basic")]
    [Required]
    [StringLength(255)]
    [DataType(DataType.Email)]
    public string EmailAddress { get;set; }

    [Display(Name = "Last Order",Description = "The date when the customer last placed an order",GroupName = "Status")]
    public DateTime LastOrderPlaced { get;set; }

    [Display(Name = "Locked",Description = "Whether the customer account is locked",GroupName = "Status")]
    public bool IsLocked { get;set; }
}

我的观点看起来像这样：

@model Customer

<div class="edit-customer">
    @foreach (var property in ViewData.ModelMetadata.Properties.Where(p => !p.IsReadOnly).OrderBy(p => p.Order))
    {
        <div class="editor-row">
            @Html.DevExpress().Label(settings =>
                {
                    settings.AssociatedControlName = property.PropertyName;
                    settings.Text = property.DisplayName;
                    settings.ToolTip = property.Description;
                }).GetHtml()
            <span class="editor-field">
                @Html.DevExpress().TextBox(settings =>
                    {
                        settings.Name = property.PropertyName;
                        settings.Properties.NullText = property.Watermark;
                        settings.Width = 200;
                        settings.Properties.ValidationSettings.RequiredField.IsRequired = property.IsRequired;
                        settings.ShowModelErrors = true;
                    }).Bind(ViewData[property.PropertyName]).GetHtml()
            </span>
        </div>
    }
</div>

然后根据元数据很好地布置表单,标签,工具提示,水印等都从模型的元数据中拉出;但是,我希望能够将这些项目组合在一起,例如在< fieldset>中.每组.有没有人知道如何从元数据中获取GroupName,而不是为ModelMetadata编写扩展方法？
