我正在尝试将基于 Umbraco v7 构建的站点中的一些代码复制到基于 Umbraco v8 构建的站点中,但是新版本中似乎不存在某些类。这是我要复制的课程:

上面public partial class BaseImage
有一个属性 ( PublishedContentModel("baseImage")
),但这在 v8 中似乎不存在。在 v7 中,当我查看定义时,我看到了 PublishedContentModelAttribute,它是 Umbraco.Core.Models.PublishedContent 命名空间的一部分。在v8中有替代品吗?
在 GetModelContentType 方法中有对 PublishedContentType.Get 的调用,但在 v8 中的 Umbraco.Core.Models.PublishedContent 命名空间中也缺少 Get 方法。有什么建议我可以改用吗?
在 GetModelPropertyType 方法中有对 PublishedContentModelUtility.GetModelPropertyType 的调用,但 PublishedContentModelUtility 似乎不再存在于 Umbraco.ModelBuilder.Umbraco 中。v8有替代品吗?
此外,还有几个对 that.GetPropertyValue 的调用,它们应该在 Umbraco.Web.PublishedContentExtenions 命名空间中,但在 v8 中找不到。谁能建议我可以使用什么代码?
我意识到这里有几个问题,但它们都是同一个问题的一部分,都阻止我完成任务。
