無法從字符串值加載類型

我正在創建一個使用NHibernate和Spring.Net框架的程序。當我執行的應用程序，然後我得到以下異常無法從字符串值加載類型

錯誤創建上下文「spring.root」：無法加載從字符串值「BlackOpsP2.Data.EmployeeDao，BlackOpsP2.Data」類型。

這裏我有配置文件。

我已經實現了以下目錄結構。

ABC.Core
ABC.Data
ABC.Presentation
ABC.Services
ABC.UI

我經歷很多環節上了計算器，通過谷歌，但無法找到解決我的問題的相關信息。

我不知道爲什麼這個異常即將到來，我不知道如何解決它。我認爲這與輸出目錄有關，或者彈簧框架無法找到dll。

這裏我給出了一個詳細的跟蹤異常，我得到了。

[更新]

當我已經加入下列中的app.config線然後錯誤消息改變。

<property name="MappingAssemblies"> 
       <list> 
        <value>BlackOpsP2.Core</value> 
        <value>BlackOpsP2.Data</value> 
       </list> 
</property>

和錯誤消息，這我得到

錯誤創建上下文「spring.root」：無法加載文件或程序集「BlackOpsP2.Data」或它的一個依賴。該系統找不到指定的文件。

是任何身體知道爲什麼它正在發生..

看起來像它找不到類型BlackOpsP2.Data.EmployeeDao或程序集BlackOpsP2.Data – Maxim

我知道它但我不知道如何給它 – Awadhendra

我已經解決了這個問題。其實有兩個小錯誤。

資質的單位名稱是不正確
需要添加引用的所有DLL未UI DLL。

謝謝，文本暴擊的

很高興你能解決它。你可以接受你自己的答案，但只能在一段時間後。 – Marijn

請注意，您實際上不必引用其他庫，但程序集必須與您的exe相同。 – Marijn

雅，但是當我們引用程序集時，那些程序集自動進入相同的目錄。不管怎樣，謝謝 – Awadhendra
