macros - 使用 Razor 脚本在 Umbraco 中随机选取一个页面节点

Question

以下代码在 http://www.keelycattschoolofdance.co.uk 的主页上显示一个推荐项效果很好:

@using umbraco.MacroEngines;
@inherits umbraco.MacroEngines.DynamicNodeContext

@{ 
var numberOfItems = 1;
DynamicNodeList pages = @Model.Children.Where("umbracoNaviHide !=    true").Take(numberOfItems).OrderBy("UpdateDate");
}

<div>
    @foreach (DynamicNode page in pages)
    {        
       <h2>@page.Name</h2>
       <p>@page.GetProperty("introText")</p>
       <p><a href="@page.Url">Read more...</a></p>
       <p><strong>@page.GetProperty("personsName")</strong></p>                       
    }
</div>

我想通过选择随机推荐来进一步发展这个小脚本。我应该怎样做呢？

尝试

var r = new Random();
var numberOfItems = 1;
List<DynamicNode> pages = new DynamicNode(Model.Id).Descendants().Items.Where(x => x.Visible).OrderBy(x => r.Next()).Take(numberOfItems).ToList();
