如何从Orchard CMS中的分配的contentpart中获取值

我正在使用Orchard CMSv1.8.x。我们添加了FlexSlider模块，并使其链接到站点的特定区域，我们在FlexSliderPart对象中添加了一个名为“幻灯片链接”的字段。

现在，所有这些工作都非常简洁。但是我绝对不知道如何在前端引用这个新领域。FlexSliderWidgetViewModel仅包含“标题”和“图像路径”的字段。我不知道如何检索SlideLink（和SubTitle）字段：

namespace Tekno.FlexSlider.ViewModels
{
    public class FlexSliderWidgetViewModel
    {
        public string Title { get; set; }
        public string ImagePath { get; set; }


    }
}

我的看法：

@using Tekno.FlexSlider.ViewModels

@{
    Style.Require("FlexSlider");
    Script.Require("FlexSlider");

    var items = (IEnumerable<FlexSliderWidgetViewModel>)Model.SlideItems;
}
<div class="flexslider">
    <ul class="slides">
        @foreach (var item in items)
        {
            <li>
                @if (item.ImagePath != "")
                {
                    <a href="@(/*what must I do here?*/)"><img src="@Display.ResizeMediaUrl(Path: item.ImagePath, Height: 400, Mode: "crop")" /></a>
                }
                <span class="slide-text">@item.Title</span>
            </li>
        }
    </ul>
    <span class="slide-text-bottom"></span>
</div>

驾驶员显示功能：

protected override DriverResult Display(FlexSliderWidgetPart part, string displayType, dynamic shapeHelper)
        {
            var items = _contentManager.Query<FlexSliderPart, FlexSliderPartRecord>("FlexSlider")
                                       .Where(i => i.GroupId == part.GroupId).OrderBy(i => i.Sort)
                                       .List()
                                       .Select(i => new FlexSliderWidgetViewModel()
             {
                 ImagePath = ((MediaLibraryPickerField)i.Fields.Single(f => f.Name == "Picture"))
                                                        .MediaParts
                                                        .FirstOrDefault() == null ? "" : ((MediaLibraryPickerField)i.Fields.Single(f => f.Name == "Picture")).MediaParts.First().MediaUrl,
                 Title = i.Get<TitlePart>().Title

             });

            return ContentShape("Parts_FlexSliderWidget",
                () => shapeHelper.Parts_FlexSliderWidget(SlideItems: items));
        }
