Loading Json from Resources via Editor Script

Hey folks,

So I'm taking my first real look at Editor Scripts and I'm having a bit of difficulty loading and reading a Json file in the way I want to. I find it quite hard without the ability to Debug, which I'm presuming you can't do in an Editor Script?

So what I'm trying to do is Load a Json file and then compile a drop down menu in the inspector which will be populated by the entries from a particular field in the Json.

This is where I'm at:

 using UnityEngine;
 using UnityEditor;
 using System;
 using System.Collections;
 using System.Text;
 using System.Collections.Generic;
 using JsonFx.Json;
 
 
 public class TileEditor : EditorWindow
 {
 
     public string[] Name;
 
     [MenuItem("Tools/Tile Editor")]
     static void Init()
     {
         EditorWindow window = GetWindow(typeof(TileEditor));
         window.Show();
     }
 
     public void OnGUI()
     {
         Name = EditorGUILayout.TextField("The Name is", Name);
 
         if (GUILayout.Button("Load Tile"))
         {
             DisplayAvailableTiles();
         }
 
     }
 
     void DisplayAvailableTiles()
     {
         string filePath = "Data/graph/Tiles.json";
 
         TextAsset targetFile = Resources.Load<TextAsset>(filePath);
 
         foreach (var item in targetFile)
         {
             Name.Add(item.Name);
         }
 
 
     }
 
 }
