Using Array.Copy in 2d Array

Question

I have a 2 dimensional array.
Like,
(0,1)
(0,2)
(0,3)
(1,1)
(1,2)
(1,3)
(2,1)
(2,2)
(2,3)

How can i use Array.Copy to copy only the 2nd index in a new array.
Like only,
(2,1)
(2,2)
(2,3)

Or is there any other way.

You could use a foreach construction.. but that is probably not realy effcient. — Bart Teunissen

@BartTeunissen not really efficient? There are not too many things more efficient than looping through simple arrays. There you have a link (in C# but instructive anyway): stackoverflow.com/questions/7483893/… — user2480047

I understand that thats the case, but a foreach loop is more than one line of code, and i wasn't sure if there was an easier sollution.. that is what is was trying to say. — Bart Teunissen

@varocarbas...please suggest an answer...not able to conclude with the link — user2322507

@BartTeunissen All clear. But some times, lines of code and efficiency are mixed up: a lower number of lines does not mean higher efficiency. A single line can call a really complex set of functions. For example, the "simple" arrays require more lines of code than "more complex" collection (e.g., List); but they are much more efficient as far as the complex collections need more resources to perform each single action. — user2480047
