Parsing JObject properly-CodePudding

I would like to parse the following json

{
  "status": 1,
  "data": {
  
    "xyz": [
      [
        3.5927680391473826,
        0.5641835941824296,
        -0.88546609584117
      ],
      [
        3.5885032091080853,
        0.7537851201209402,
        -0.9748245317650808
      ]
    ],
    "xy": [
      [
        479,
        32
      ],
      [
        435,
        85
      ]
    ]
  }
}

I'm using the following code to do so,

resultantData = JObject.Parse(inputString)
List<float> xyz = resultantData["data"]["xyz"].Value<List<List<float>>>();
List<int> xy = resultantData["data"]["xy"].Value<List<int>>();

Unfortunately, the above code wasn't able to parse the JSON properly. What am I missing?

CodePudding user response：

I think you can do it using JsonConvert.DeserializeObject

var result = JsonConvert.DeserializeObject<Root>(inputString);

public partial class Root
{
    [JsonProperty("status")]
    public long Status { get; set; }

    [JsonProperty("data")]
    public Data Data { get; set; }
}

public partial class Data
{
    [JsonProperty("xyz")]
    public List<List<double>> Xyz { get; set; }

    [JsonProperty("xy")]
    public List<List<long>> Xy { get; set; }
}

CodePudding user response：

you have list of lists , not just list

List<List<float>> xyz = resultantData["data"]["xyz"].ToObject<List<List<float>>>();
List<List<int>> xy = resultantData["data"]["xy"].ToObject<List<List<int>>>();

you can use it like this

if (xyz != null && xyz.Count > 0)
{ 
    List<float> xyz1 = xyz[0];
}

if you want to put everything in one pile, I don't think that it is a good idea , you have to try this

List<float> xyz = resultantData["data"]["xyz"].ToObject<List<List<float>>>()
.SelectMany(i=> i).ToList();
List<int> xy = resultantData["data"]["xy"].ToObject<List<List<int>>>()
.SelectMany(i=> i).ToList();
