예기치 않은 EntityObject 오류

Question

나는 다음과 같은 코드를 가지고 :

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); 
    } 
} 

하지만 이러한 오류를 얻을 이유를 모르겠어요 :

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'.

가 어떻게 이러한 오류를 고칠 수 있습니까?

Answer 1

나는 당신과 같이 간단하게이 작업을 수행 할 수 있다고 생각 :

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

당신이 필요한 참조 및 사용하여 문이 있는지 확인합니다.

희망이 있습니다.
