That's true if you only need to back up one record.

List<int> data = new List<int>();
using(SqlDataReader reader = getTheReader()){
   if(reader.HasRows)
   {
       int ordinal = reader.GetOrdinal("YourColumnName");
       while(reader.Read())
         data.Add(reader.GetInt32());
   }
   reader.Close();
}

// contents of reader is in list data  Use that to do comparison
