如何将列表类转换为类数组

问题描述

public class PGNsegmentTxMap
    {

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



         public string PGN
         {
             get
             {
                 if (!String.IsNullOrEmpty(pgn))
                     return pgn.ToUpper();
                 else
                     return string.Empty;
             }

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

     class ProductComparer : IEqualityComparer<PGNsegmentTxMap>
     {
         // Products are equal if their names and product numbers are equal. 
         public bool Equals(PGNsegmentTxMap x, PGNsegmentTxMap y)

             //Get hash code for the Name field if it is not null. 
             int hashProductName = product.segmentTx == null ? 0 : product.segmentTx.GetHashCode();

             //Get hash code for the Code field. 
             int hashProductCode = product.PGN.GetHashCode();

             //Calculate the hash code for the product. 
             return hashProductName ^ hashProductCode;
         }



     }

推荐答案

        PGNsegmentTxMap[] products = PGNsegmentMapLists.ToArray();
