意外的EntityObject错误

Question

我有以下代码：

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);
    }
}

但是我不知道为什么我会得到这些错误：

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'.

如何修复这些错误？

Answer 1

我认为你可以简单地这样做：

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

确保您有必要的引用和using语句。

希望这能有所帮助:)
