意外EntityObject錯誤

我有以下代碼：意外EntityObject錯誤

public IList<T_CLIENT> Get_All_Obj() 
{ 
    try 
    { 
     IList<T_CLIENT> LesListe; 
     using (FaExpedEntities oEntite_T = new FaExpedEntities()) 
     { 
      var query = from o in oEntite_T.T_CLIENT select o; 
      LesListe = query.ToList(); 
     } 
     return LesListe; 
    } 
    catch (Exception excThrown) 
    { 
     throw new Exception("Err_02", excThrown); 
    } 
}

但我不知道爲什麼我得到這些錯誤：

Error 1 The type 'System.Data.Objects.DataClasses.EntityObject'is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Entity, Version = 4.0.0.0, Culture = neutral, PublicKeyToken = b77a5c561934e089'.

如何解決這些錯誤？

這是在您的開發人員機器上還是在另一臺機器上？你有沒有確保System.Data.Entity在你的bin文件夾中？ – 2011-04-20 08:36:26

聽起來像你缺少一個參考。 – 2011-04-20 10:13:40

解決方案的結構是什麼？ EF數據模型（EDMX）是否在另一個項目中，而不是託管上述代碼的項目？ – 2011-04-20 14:42:14

我認爲你可以簡單地做到這一點，像這樣：

var entities = new FaExpedEntities(); 
return entities.T_CLIENT.ToList();

請確保您有必要引用和using語句。

希望這有助於:)
