for (int i = 0; i < PGNsegmentMapLists.Count; i++)
            PGNsegmentTxMap[] products = PGNsegmentMapLists[i];

        PGNsegmentTxMap[] products = PGNsegmentMapLists.ToArray();

It works fine
But when I am trying like below
IEnumerable<PGNsegmentTxMap> noduplicates = products.Distinct(new ProductComparer());
it is not giving distinct values of products into noduplicates
Can you help me in solving this

change this ProductComparer such a way that it will compare the exact duplicates..
or post the ProductComparer

Now I updated my question with class and productComparer
please check it
