Question

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.

names.Any(x => subnames.Contains(x))
