My apologies! I'll add the Dict code.. (btw, some closing brackets are probably missing, as well as possibly some using statements, I was trying to cut stuff out for brevity). Thanks for looking at this... Sean using System; using System.Collections; using System.Collections.Specialized; using System.IO; namespace nltk { namespace probability { public delegate ProbDist CreateProbDistDelegate(FreqDist fdist, params object[] args); #region Helper Classes public class Dict: Hashtable { private ArrayList keys = new ArrayList(); public override object this[ object key ] { get { return( base[key] ); } set { if (!keys.Contains(key)) keys.Add(key); base[key] = value; } } public string[] GetKeys { get { string[] results = new string[keys.Count]; keys.CopyTo(results); return( results); } } public override string ToString() { string result = ""; foreach (string key in Keys) { result += key + ":" + base[key].ToString() + " "; } return result; } public override void Add( object key, object value ) { if (!keys.Contains(key)) keys.Add(key); base.Add(key, value); } public override void Remove( object key ) { keys.Remove(key); base.Remove( key ); } public int Length { get { return base.Count; } } } #endregion --- Thane <thane@magna-capital.com> wrote:

Sean, I can't get your C# code to compile. The complaint is about "Dict".
