在一个Json中创建多个表而不使用JArray?

我正在做一个IMDB类型的程序,在那里我列出的人谁有一个电影,唱片,和类似的。所以我已经在MVVM中创建了我的视图,现在我正在尝试序列化json以匹配它。现在我正在整理我的桌子,就像这样:

dynamic discography = new JObject(new JProperty("DiscographyVM", jsonDiscography));
dynamic filmography = new JObject(new JProperty("FilmographyVM", jsonFilmography));

dynamic fullJson = new JArray();
fullJson.Add(discography);
fullJson.Add(filmography);

[
  {
    "Discography" : [
      { 
        "Album" : "MyAlbum",
        "Year" : 2017
      },
      { "Album" : "MySecondAlbum",
        "Year" : 2018
      }
    ],
    "Filmography" : [
      {
        "Film" : "MyFirstMovie",
        "Year" : 2017
      },
      {
        "Film" : "MySecondMovie",
        "Year" : 2018
      }
    ]
  }
]

我要做的是去掉外面的 [ ] 括号。所以我想我需要改变我的想法 dynamic fullJson

更新,我正在尝试获取以下结构:

  {
    "Discography" : [
      { 
        "Album" : "MyAlbum",
        "Year" : 2017
      },
      { "Album" : "MySecondAlbum",
        "Year" : 2018
      }
    ],
    "Filmography" : [
      {
        "Film" : "MyFirstMovie",
        "Year" : 2017
      },
      {
        "Film" : "MySecondMovie",
        "Year" : 2018
      }
    ]
  }
