Hello,

i am willing to generate a json string containing the structure of a given folder, searching where to start, i found that is easy using .NET but i don’t know why i didn’t get it in unity, maybe it is obvious, but excuse me for this if so, i am just a beginner. Thank you.

Hi again,

i managed to code this:

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using Pathfinding.Serialization.JsonFx;
using System.IO;

public class JBrowser : MonoBehaviour
{

	private string title ;
	private bool isFolder ;
	private string key ;
	private List<string> children;
	private  DirectoryInfo fsi;
	private StreamWriter streamWriter;
	private bool on = true;


	void Start ()
	{
		fsi = new DirectoryInfo (@"c:\");
		title = fsi.Name;
		Debug.Log (title);
		children = new List<string> ();
	}

	void Update ()
	{
		if (on) {
			if (fsi.Attributes == FileAttributes.Directory) {
				isFolder = true;
				foreach (FileSystemInfo f in fsi.GetFileSystemInfos()) {
					children.Add (f.Name.ToString ());
				}
			} else {
				isFolder = false;
			}
			key = title.Replace (" ", "").ToLower ();
			
			//		JsonToDynatree ();
			//	}
			//		
			//
			//	private void JsonToDynatree ()
			//	{
			string data = JsonWriter.Serialize (children);
			//		if(!Directory.Exists(PATH)){
			//			Directory.CreateDirectory(PATH);
			//		}
			streamWriter = new StreamWriter (@"c:\JsonBrowsingList.txt");
			streamWriter.Write (data);
			streamWriter.Close ();
			//		return JsonConvert.SerializeObject (this, Formatting.Indented);
			on = false;
		}
		
	}

}

and i ve created the json.txt file in the c:/ drive, and it is supposed to be filled with the folders and files names but instead is only showing empty brackets… ?? ()

Old question, but maybe others will land here,
(Have a look at this post)
https://stackoverflow.com/questions/24725775/converting-a-directory-structure-and-parsing-to-json-format-in-c-sharp

Just change out to your preferred parser.

public string JsonToDynatree()
{
  //return JsonConvert.SerializeObject(this, Formatting.Indented);
  return JsonUtility.ToJson(this, true);
}
