JsonUtility not working with Arrays

Questions & Answers
1

Hello,

I’m having a problem serializing an array into json. I am using Unity’s JsonUtility and I thought they were supported since some people said it here. Anyways if it isn’t supported how could I do it without, if it is, then why does this code not work?

// Test array that will be converted
string[] test = new string[] { "test", "Hello World"};

// Get the length of the array to convert
Debug.Log(test.Length);

// Convert array to json
string json = JsonUtility.ToJson(test);

// This returns {}
Debug.Log(json);

For some reason my output is

2
{}

Thanks!

Thanks to @Bunny83, it works now!

All I had to do was put the array inside it’s own custom class and then mark that class as [Serializable]
and just use ToJson with that object instead.

This works…you need an Object to define the call for JSON.

using UnityEngine;
using System.Collections;

public class MaterialController : MonoBehaviour {

// Use this for initialization
void Start () {
	//store the retrieved JSON object to a string
	string json =  "";

	TestObject testobj = new TestObject();

	testobj.test = "My test string";

	json = JsonUtility.ToJson(testobj);
		 
	Debug.Log (json);
}


//*************************************************
// JSON Object structure for JSON Decoding. 
//*************************************************
[System.Serializable] public struct TestObject {

	public string test;

}

}
