Cant get helper C# class into UnityScript variable

I wrote a C# class with a number of parsing functions for a large string of data. I want to call it like this:

Code (csharp):

1. var dataToParse = "..very..long..string";
2. var myData: MyClassName = new MyClassName (dataToParse);
3.  
4. myData.Parse();
5. myData.Count();
6. myData.Execute();
7. // Ect...

In my CS file I have something like:

Code (csharp):

1. public class MyClassName : MonoBehaviour{
2.  
3.   private string _rawCode;
4.   private ArrayList _parsedCode;
5.  
6.  // I can't get a constructor to work
7.   void Init(string dataIn) {
8.     _rawCode = dataIn;
9.   }
10.  
11.   public int Count () {
12.     return _parsedCode.Length;
13.   }
14.  
15.   ...
16.  
17. }
18.  

When I try to define in it in the UnityScript code, I get this error:

I recall getting something like this to work a while ago in Unity v2.x. I've upgraded to v3.0 and I'm tripping over what I thought was a pretty common usage of a helper class. Have things changed and how does one do this in v3.0?

Thanks for any info!

 

Unless they changed it, I think you need to put your C# classes in some "Plugins" directory first or something like that. Maybe http://unity3d.com/support/documentation/ScriptReference/index.Script_compilation_28Advanced29.html can help you.

I've never had to do it, so I can only guess.
