Sitecore Glass Mapper：「程序集中的重複類型名稱」錯誤

我在使用Glass Mapper SitecoreService獲取項目時遇到問題。該項目肯定存在，類型是正確的。（它由TDS生成）。Sitecore Glass Mapper：「程序集中的重複類型名稱」錯誤

var language = Language.Parse("en-GB"); 
var service = new SitecoreService("master");     
var targetPath = String.Format("{0}-migrated", Constants.SourceProviderListPageItem); 
var target = service.GetItem<IProvider_List_Page>(targetPath, language);

上面代碼導致當service.GetItem <Ť>被稱爲以下例外。

你有完整的堆棧跟蹤嗎？ –

嗨邁克爾，感謝您的幫助 - 我已經按要求添加了堆棧跟蹤。 –

看起來你正在使用[Interface as Model]（http://glass.lu/Mapper/Sc/Tutorials/Tutorial21.aspx）。由於您使用的是TDS，因此也會生成具體的類，請嘗試使用「Provider_List_Page」。我的猜測是接口和具體的存在都在這裏引發問題，但@邁克爾愛德華茲將能夠確認... – jammykam

如果您使用的使用從刺蝟T4 code generation templates然後將生成的C＃類文件將包含兩個接口和具體類自動生成的類文件。

由於您使用的是從Sitecore獲取內容的界面，因此您實際上正在使用Interfaces as Models。我還沒有深入研究Glass Mapper，但我的猜測是Interface和Concrete的存在在這裏引發了一些問題。

相反，使用具體類：

var target = service.GetItem<Provider_List_Page>(targetPath, language);

你可以，如果你需要與IProvider_List_Page更換var型。
