Hashtable deep copy

[TheVillain9]

I'm adding key-values to my hashtable (company_data), but everytime I add something new, it adds it to the element from which the hashtable was derived, Universe[ i ]. Universe is just an arraylist of hastables that is declared as a member of the class. Its creating a reference i'm guessing to the original element instead of copying just the actual values. How do I fix this?

            for(int i=0; i<Convert.ToInt32(Universe.Count*0.1); i++)
            {    
                Hashtable company_data = new Hashtable();
                company_data = (Hashtable)Universe[ i ];
                Hashtable dm = report.DownloadMnemonics_pri();    
                foreach(string key in dm.Keys)
                {
                    company_data.Add(key,GetFactSetData(company_data["ticker"].ToString(),dm[key].ToString()));
                }
                
                report.Add(company_data);
                ReportProgressToClient(i,Convert.ToInt32(Universe.Count*0.1),"FactSet Download: " + company_data["ticker"].ToString(), ProgressType.CURRENT_PROGRESS);
                dm = null;
                company_data = null;
                GC.Collect();
                GC.WaitForPendingFinalizers();
            }

Thanks for the help.
