I have a an array of strings:e.g:

string [] names ={"P","A","B","G","F","K","R"}

I have another array :

string [] subnames={"P","G","O"}

How can we check whether names array has any elements of subnames array.

In the above example "P" and "G" are there in names.

Linq is the simplest I think:

from n1 in names
join n2 in subnames on n1 equals n2
select n1;
