Question by scarffy · Nov 23, 2020 at 07:01 AM · jsondeserializationdeserialize

JSON invalid value

Hi all,
By using Unity JSON utility, is there a way to check if json is valid?
I want to do something like this but have no idea how to check if json is valid

 string json = wr.downloadHandler.text;
 
 if(json.isvalid){
   jsonObject obj  = JsonUtility.FromJson<jsonObject >(json );
 }
 else{
   // Handle error here
 }

Can someone guide me or shine a bit of light on this?

Thank you

There is not a valid property because it depends if you try to cast it to a jsonObject will work but if you cast it to another type it will not, so there is no a simply "general" way of knowing if the json is valid

  string json = wr.downloadHandler.text;
  jsonObject obj  = JsonUtility.FromJson<jsonObject >(json );
 
  if(obj == null)
  {
     // Handle error here
  }
