I have to be honest I haven't used many generics in my coding; I
really want to start using more of them but  am having trouble with
what is the best way to use a generic with my Send method because the
Send method needs to point to different data factories. I really would
like to hear some suggestions.

using System.Collections;
using System.Data.SqlClient;
using Microsoft.SqlServer.Server;
using System.Xml;

   public class Groups
   {
       #region Fields
       ArrayList m_items = new ArrayList();
       #endregion

       #region Properties
       public virtual Group this[int index]
       {
           get
           {
               return (Group)m_items[index];
           }
       }
       #endregion

       #region Constructors
       public Groups(Group[] objs)
       {
           foreach (Group obj in objs)
           {
               this.List.Add(obj);
           }
       }

       internal Groups(SqlDataReader dbReader)
       {
           while (dbReader.Read())
           {
               m_items.Add(new Group(dbReader));
           }
       }
       #endregion

       #region Methods
       public virtual void Add(Group obj)
       {
           this.List.Add(obj);
       }

       public virtual Group[] ToArray()
       {
           return (Group[])m_items.ToArray(typeof(Group));
       }

       public void Send()
       {
           SqlDataRecord dbRecord = new
SqlDataRecord(Factory.Catalog.MetaData);

           SqlContext.Pipe.SendResultsStart(dbRecord);

           foreach (Catalog catalog in base.List)
           {
               Factory.Catalog.SendResultsRow(catalog, dbRecord);
           }

           SqlContext.Pipe.SendResultsEnd();
       }
