删除外括号并使用数字命名对象吗？

Question

我真的对json感到困惑(我还在学习json )。

我想要的JSON：

{  "entityMap": {
    "0": {
      "type": "LINK",
      "mutability": "MUTABLE",
      "data": {
        "url": "https://stackoverflow.com/"
      }
    },
    "1": {
      "type": "LINK",
      "mutability": "MUTABLE",
      "data": {
        "url": "https://stackoverflow.com/"
      }
    },
    "2": {
      "type": "LINK",
      "mutability": "MUTABLE",
      "data": {
        "url": "https://stackoverflow.com/"
      }
    },
    "3": {
      "type": "LINK",
      "mutability": "MUTABLE",
      "data": {
        "url": "https://stackoverflow.com/"
      }
    }
  }
}

这被认为是糟糕的json吗？以及如何使用这样的数字命名json？

到目前为止，我得到的就是这些。

{
    "entityMap": [
        {
            "type": "LINK",
            "mutability": "MUTABLE",
            "data": {
                "url": "https://stackoverflow.com/"
            }
        },
        {
            "type": "LINK",
            "mutability": "MUTABLE",
            "data": {
                "url": "https://stackoverflow.com/"
            }
        },
        {
            "type": "LINK",
            "mutability": "MUTABLE",
            "data": {
                "url": "https://stackoverflow.com/"
            }
        }
    ]
}

这是我的课

    public class editorRawTest
    {
        public List<entityMapItem> entityMap { get; set; }

    }


    public class entityMapItem
    {
        public string type { get; set; }
        public string mutability { get; set; }
        public entityMapItemData data { get; set; }
    }

    public class entityMapItemData
    {
        public string url { get; set; }

    }

我的执行代码：

                var map = new List<entityMapItem>();

                var mapitem = new entityMapItem() { type = "LINK", mutability = "MUTABLE", data = new entityMapItemData() { url = "https://stackoverflow.com/" }  };

                map.Add(mapitem);
                map.Add(mapitem);
                map.Add(mapitem);



                editorRawTest bc = new editorRawTest() { entityMap = map };

                string JSONresult = JsonConvert.SerializeObject(bc);
                string path = @"jsonmapdata.json";
                using (var tw = new StreamWriter(path, true))
                {
                    tw.WriteLine(JSONresult.ToString());
                    tw.Close();
                }

搜索谷歌和堆栈溢出没有运气。任何线索或帮助都将不胜感激。

谢谢。

要获得第一个JSON，您需要将List<entityMapItem>替换为Dictionary<string, entityMapItem>，如下所示：

public class editorRawTest
{
    public Dictionary<string, entityMapItem> entityMap { get; set; }
}

然后您需要像这样填充它：

var map = new Dictionary<string, entityMapItem>();

var mapitem = new entityMapItem() { type = "LINK", mutability = "MUTABLE", data = new entityMapItemData() { url = "https://stackoverflow.com/" }  };

for (int i = 0; i < 4; i++)
{
    map.Add(i.ToString(), mapitem);
}

但除非迫不得已，否则我不会鼓励你这么做。您现在所拥有的(列表中的第二个JSON )更容易使用。如果您可以在这两种方法中进行选择，最好选择第二种方法。有关原因，请参阅Using json key to store value, is it a good approach?。
