Hi
I am using below code to copy data.

SQL

elements = this.Where(el => !el.Key.StartsWith("."))
                .ToDictionary(el => el.Key, el => el.Value
                    .ToDictionary(p => p.Key, p => p.Value));

It throws error if key already added. I used Distinct() method too. But no luck.

Can you please any body help me out.

Thanks in advance

Maybe off-topic: you say "copy data". You do not copy the leaf data, you only refer to them assuming they are reference types.
