将json字符串转换为多维数组

Question

目前这是我的 JSON 数组：

{"1": [{"11": [[1, 1],[2, 2],[3, 3]],"21": [[1, 1],[2, 2],[3, 3]],"31": [[1, 1],[2, 2],[3, 3]]}],"4": [{"12": [[1, 1],[2, 2],[3, 3]],"22": [[1, 1],[2, 2],[3, 3]],"32": [[1, 1],[2, 2],[3, 3]]}],"6": [{"13": [[1, 1],[2, 2],[3, 3]],"23": [[1, 1],[2, 2],[3, 3]],"33": [[1, 1],[2, 2],[3, 3]]}]}

我想把它转换成Dictionary<int, Dictionary<int, Dictionary<int, int>>>

我已经搜索了很长时间，但找不到可能的解决方案。到目前为止，我有：

Dictionary<int, Dictionary<int, Dictionary<int, int>>> menus = new Dictionary<int, Dictionary<int, Dictionary<int, int>>>();

        JToken entireJson = JToken.Parse(rawDirectory);

        foreach (var item in entireJson.Children())
        {
            var property = item as JProperty;
            var subArray = new Dictionary<int, Dictionary<int, int>>();
            foreach (var subItem in property.Value.Children())
            {
                var subProperty = subItem as JProperty;
                var subSubArray = new Dictionary<int, int>();
                foreach (var subSubItem in subItem)
                {
                    var subSubProperty = subSubItem as JProperty;
                    subSubArray.Add(int.Parse(subSubProperty.Name), int.Parse((String)subSubProperty.Value));
                }
                subArray.Add(int.Parse(subProperty.Name), subSubArray);
            }
            menus.Add(int.Parse(property.Name), subArray);
        }

编辑 - 解决方案

要生成我想要的Dictionary<>，我必须稍微更改一下 JSON 数组。当您使用方括号 [] 时，它会创建一个 List<>。当您使用大括号时，您可以生成Dictionary<>。

我已通过将 jSON 字符串更改为：

{"1": {"11": {"1": 1,"2": 2,"3": 3},"21": {"1": 1,"2": 2,"3": 3},"31": {"1": 1,"2": 2,"3": 3}},"4": {"12": {"1": 1,"2": 2,"3": 3},"22": {"1": 1,"2": 2,"3": 3},"32": {"1": 1,"2": 2,"3": 3}},"6": {"13": {"1": 1,"2": 2,"3": 3},"23": {"1": 1,"2": 2,"3": 3},"33": {"1": 1,"2": 2,"3": 3}}}

并使用以下代码进行反序列化：

JsonConvert.DeserializeObject < Dictionary<int, Dictionary<int, Dictionary<int, int>>>>(jSONString)

这就是我生成三维数组的方式：

"{" + string.Join(",", dict.Select(a => String.Format("\"{0}\": {1}", a.Key, String.Join(",", "{" + String.Join(",", a.Value.Select(b => String.Format("\"{0}\": {1}", b.Key, String.Join(",", "{" + String.Join(",", b.Value.Select(c => String.Format("\"{0}\": {1}", c.Key, String.Join(",", c.Value)))) + "}")))) + "}")))) + "}"

Answer 1

当您尝试解析时，您的 json 不是 Dictionary<int, Dictionary<int, Dictionary<int, int>>>。

是Dictionary<int,List<Dictionary<int,List<List<int>>>>>

下面的代码可行，但使用这种结构并不容易。

string json = @"{""1"": [{""11"": [[1, 1],[2, 2],[3, 3]],""21"": [[1, 1],[2, 2],[3, 3]],""31"": [[1, 1],[2, 2],[3, 3]]}],""4"": [{""12"": [[1, 1],[2, 2],[3, 3]],""22"": [[1, 1],[2, 2],[3, 3]],""32"": [[1, 1],[2, 2],[3, 3]]}],""6"": [{""13"": [[1, 1],[2, 2],[3, 3]],""23"": [[1, 1],[2, 2],[3, 3]],""33"": [[1, 1],[2, 2],[3, 3]]}]}";

var dict = JsonConvert.DeserializeObject<Dictionary<int,List<Dictionary<int,List<List<int>>>>>>(json);
