我有一个具有以下结构的JSON请求：

"formats":  {
        "flash_embed": "http://a3.vikiassets.com/assets/vikiplayer-922746a667cfd38137a7e45df6ba1b95.swf?auto_play=true&language_codes=en&media_id=74965&partner=16&source=api_v3",
        "m3u8": "http://wpc.354a.edgecastcdn.net/00354A/videos/encoded/74965/ios.m3u8",
        "res-150p": "http://wpc.354a.edgecastcdn.net/00354A/videos/encoded/74965_mp4cell_150.mp4",
        "res-240p": "http://wpc.354a.edgecastcdn.net/00354A/videos/encoded/74965_240p.mp4",
        "res-270p": "http://wpc.354a.edgecastcdn.net/00354A/videos/encoded/74965_270p.mp4",
        "res-360p": "http://wpc.354a.edgecastcdn.net/00354A/videos/encoded/74965_360p.mp4",
        "res-480p": "http://wpc.354a.edgecastcdn.net/00354A/videos/encoded/74965_480p.mp4",
        "res-720p": "http://wpc.354a.edgecastcdn.net/00354A/videos/encoded/74965_720p.mp4"
      }
    }

现在，res-150p在C＃中说了无效的名称，如果我给它起了另一个名字，那么在进行反序列化时我没有得到任何值，res-150p内为空。

编辑： [可序列化] MoviesListRootObject是包含Response然后Response包含的根对象Formats
