如何编写比较类以避免重复 [英] How to write compare class to avoid duplicates

问题描述

hI，



我在构造函数类列表中有重复项

我需要避免重复

我正在尝试下面的事情

hI,

I am having duplicates in my constructor class list
I need to avoid the duplicates
I am trying something like below

class Compare : IEqualityComparer<PGNsegmentTxMap>
    {
        public bool Equals(PGNsegmentTxMap x, PGNsegmentTxMap y)
        {
            return x.segmentTx == y.segmentTx && x.PGN == y.PGN;
        }
        public int GetHashCode(PGNsegmentTxMap codeh)
        {
            return codeh.segmentTx.GetHashCode();
        }
    }


for(int i=0;i<database.Count;i++)
          {

              PGNsegmentMapLists.Add(new PGNsegmentTxMap(database1[i], database[i]));

          }


          PGNsegmentTxMap[] products = PGNsegmentMapLists.ToArray();




          IEnumerable<PGNsegmentTxMap> noduplicates = products.Distinct(new Compare());

但我没有得到任何数据到noduplicates

任何人都可以帮我解决这个问题吗？





谢谢

John

But I am not getting any data into noduplicates
Can anyone help me in solving this???


Thanks
John
