Solution 1

Why not use List[^]? This is more recommended.

As far as resizing the array is concerned. Look here:

dEAR Manas:

Thanks for your answer. What is the benefits of list with respect to array and how should I extend the list?

Solution 2

Yes, you can use for example Array.Resize<t>[^] method for this.

However if the amount of elements is unknown, in most scenarios I'd prefer using a List<t>[^]

Solution 3

Of course you can use Linq:

C#

var s =  new string[] { "a", "b", "c" };
var s2 = s.Concat(new string[] { "V" }).ToArray();

or for blank array

C#

var s =  new string[] { "a", "b", "c" };
var s2 = s.Concat(new string[5]).ToArray();

Other solutions also work, and probably faster, but if you are combining arrays, Linq is probably better.
