Question by shiftybit · Jun 03, 2018 at 07:09 AM · json

Reading in JSON data using JsonUtility C#

I am having trouble reading the coordinates out of the following json data.

 {
  "type": "FeatureCollection",
  "name": "entities",
  "features": [
    {
      "type": "Feature",
      "properties": {
       "Layer": "0",
       "SubClasses": "AcDbEntity:AcDbLine",
       "EntityHandle": "92"
     },
     "geometry": {
       "type": "LineString",
       "coordinates": [
           [ 99.681262745218703, 94.695759123913035, 0.0 ],
           [ 199.681262745218703, 194.695759123913007, 0.0 ]
        ]
      }
    }
  ]
 }

Using the following C# Code

 [Serializable]
 public class CADData
 {

     public string type;
     public string name;
     public List<Feature> features;

     public static CADData CreateFromJSON(string jsonString)
     {
         return JsonUtility.FromJson<CADData>(jsonString);
     }
 }

 [Serializable]
 public class Feature
 {
     public string type;
     public Properties properties;
     public Geometry geometry;
 }

 [Serializable]
 public class Properties
 {
     public string Layer;
     public string SubClasses;
     public string EntityHandle;
     public string Text;
     public string Linetype;
 }

 [Serializable]
 public class Geometry
 {
     public string type;
     public List<float[]> coordinates;  // This is not working.
 }

JsonUtility isn't a general-purpose parser unfortunately, and can't handle nested arrays. Check out these answers:

  • https://answers.unity.com/questions/1118151/jsonutility-nested-array-deserialization.html

If Json.Net works for you, I'd stick with that.
