How can I make distinct strings of constructor separate

C#

Hi,

I am using a constructor to place the details of excel rows together

for(int i=0;i<database.Count;i++)
           {
                            
               PGNsegmentMapList.Add(new PGNsegmentTxMap(database1[i], database[i]));

           }

Constructor:

public class PGNsegmentTxMap
    {
         //string pgn;

         public string segmentTx { get; set; }
         public string pgn { get; set; }

       

        public PGNsegmentTxMap(string pgn, string segmentTx)
        {
            this.segmentTx = segmentTx;
            this.pgn = pgn;
        }
    }

Now some of the details of the constructor are repeated. How can I eliminate the repeated details of this list class.
