C# System.IO.FileLoadException加载Facebook程序集

我有以下未编译的代码：

{
    private static FacebookWrapper.FacebookService m_FacebookService;
    User m_LoggedInUser;

    public void LoginToFBApp(FacebookWrapper.FacebookService i_FacebookService)
    {
        LoginResult result = FacebookWrapper.FacebookService.Login("192940970765612",
            new string[]
            {
                "user_about_me", "friends_about_me", "publish_stream"
                //,
                //"user_activities", "friends_activities",
                //"user_birthday", "friends_birthday",
                //"user_checkins", "friends_checkins",
                //"user_education_history", "friends_education_history",
                //"user_events", "friends_events",
                //"user_groups" , "friends_groups",

                //"manage_pages",

                //"offline_access"
            },
            false);
    }

}

我正在使用一个给我的DLL，它帮助我登录facebook帐户。当激活我的程序时，该程序试图连接到facebook，但我得到了这条消息标题中显示的文本的验证。 额外信息出现在例外中：

  Could not load file or assembly 'Facebook, Version=5.0.50.0, Culture=neutral, PublicKeyToken=58cb4f2111d1e6de' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

我不明白问题到底出在哪里

你从哪里搞来的集会？这听起来像是坏了，基本上…这取决于其他东西，你似乎没有。当我进入负责登录的函数时，我在运行时收到了这条消息。什么东西会坏？
