C# conversion of JavaScript, problems with nested class as a custom type

I am trying to work through a book on Unity, "Unity 3 Game Development Hotshot"- Packt Publishing, and all the examples are in Javascript. I wish to use C# so I decided to covert as I go.

I am having issues with one of the early scripts not behaving as expected in the Inspector when translated to C#, and I was hoping the community might be able to help give me a pointer on:

1. What the problem is.

2. Where I can find the reference that might have allowed me to answer this myself. I was unable to locate any help in the manuals.

What is going on, I am creating a class as a custom type, then creating an array of that type.

When the script with the array is added to a GameObject the Inspector is suposed to allow me to enter the array size, then present me with the required number of elements in which I can access and set the public variables for each index of the array. In javascript it is doing that just fine. In C# I set the array size and it presents me with a set of elements (one for each array index) but the public variables of the custom class are not avaialable.

If I copy the custom class out and make it it's own script, then attach that script to a GameObject, the public variables are accessable and I can set them as expected. I suspect the issue is with how I am creating either the aray, or the customer object type, but am not sure where my error is. (The one thing I do know is it is something I am overlooking.)

Javascript working (edited some to avoid violating PacktPub's copyright)

 public var loopSprites : SpriteManager[];

 public function Start() : void {

 //Initialization Sprite Manager
 for (var i : int = 0; i < loopSprites.length; i++) {
     loopSprites[i].init();
 }
 //aditional code here... not relavant really
 }

 class SpriteManager {
 public var spriteTexture : Texture2D; //Set Texture use for a loop animation such as walking, stay, etc.
 public var in_framePerSec : int; //Get frame per sec to calculate time
 public var in_gridX : int; //Get max number of Horizontal images
 public var in_gridY : int; //Get max number of Vertical images
 private var f_timePercent : float;
 private var f_nextTime : float; //Update time by using frame persecond
 private var f_gridX : float;
 private var f_gridY : float;
 private var in_curFrame : int;
 
 public function init () : void {
 f_timePercent = 1.0/in_framePerSec;
 f_nextTime = f_timePercent; //Update time by using frame persecond
 f_gridX = 1.0/in_gridX;
 f_gridY = 1.0/in_gridY;
 in_curFrame = 1;
 }
 
 }

C# -Does not work

 using UnityEngine;
 using System.Collections;

 public class test2 : MonoBehaviour {
 public SpriteManager[] loopSprites;
 


 void Start () {
     //initialization of Sprite Manager
     for (int i=0; i<loopSprites.Length; i++){
         loopSprites[i].init();
     }
     // Addition code... Also not really relevant
 }
 
 public class SpriteManager : MonoBehaviour {
 
     public Texture2D spriteTexture; //Set Texture for the sprite animation
     public int framesPerSec; //Get Frames Per Second to calculate time
     public int gridXMax; //max number of horizontal images
     public int gridYMax; //max number of vertical images
     float timePercent;
     float nextTime; //next update time based on framesPerSec
     float gridXOffset;
     float gridYOffset;
     int currentFrame;
 
     public void init () {
         timePercent=1.0f/framesPerSec;
         nextTime=timePercent;
         gridXOffset= 1.0f/gridXMax;
         gridYOffset=1.0f/gridYMax;
         currentFrame=1;
     }
 
 }
 }

Any pointers would be greatly appreciated. Also Please forgive me if this is a duplicated post (or very similar), these forums are substantial, and I was not able to find any relevant topic. This may have been due to not know what to look for.
