JsonString()

To export a Hashtable (with underlying hierarchy) or ArrayList to JSON, you can call the class extensions for Hashtable and ArrayList. You need to include the line

using SimpleXmlExtensions;

in your source code.

string JsonString()

This function is defined for Hashtable and for ArrayList and returns a JSON formatted string.

Since the JsonString() function only returns a string, here's an example of writing the JSON string to a file.


using UnityEngine;
using System;
using System.Collections;
using System.Collections.Generic;

using SimpleXmlExtensions;

public class MyExporter {

	public void ExportJson(Hashtable aHash) {
		string jsonExportString = aHash.JsonString();
		ExportToFile(jsonExportString, "SimpleJsonExport.json");
	}

	private void ExportToFile(string exportString, string path) {
		if(exportString == null || path == null) return;
		if(Application.platform==RuntimePlatform.OSXPlayer || 
			Application.platform==RuntimePlatform.WindowsPlayer && 
			Application.platform!=RuntimePlatform.LinuxPlayer || Application.isEditor) {

		// We use UTF-8 encoding
	        byte[] bytes = new UTF8Encoding(true).GetBytes(exportString);
	        if(File.Exists(path)) File.Delete(path); // delete if it exists
				FileStream fs = new FileStream(path, FileMode.OpenOrCreate);
			BinaryWriter w = new BinaryWriter(fs);
			w.Write(bytes);
			w.Close();
			fs.Close();
	    }
	}
}
