thanks , but it does not give a clue of how to solve my problem.

Actually, yes it does, and quite easily solves your problem if you bother to try and understand it.

You can use the information in those links with either a loop or a LINQ expression.

If you're looking for code to be written for you to do this, you've come to the wrong place.

Solution 2

List(T) members (VB.NET)[^]

look at the find and findall methods.
