c# adding a string to an array [duplicate]

Question

i want to simply add a string to an array, like this:

string[] arrayName = new string[0];
        arrayName.Add("raptor");

But this doesn't work, can someone help me?

arrays are immutable. when you create array of size 0 you cant change it. the only way is to recreate a new array with bigger size. (which list does) — M.kazem Akhgary

Another way to do this (although I definitely recommend the use of generic collections) would be to resize your array, that's if you wanted to stick with arrays. Array.Resize(ref arrayName, 1); arrayName[0] = "raptor"; You could wrap that up in your own Add method if you must. — user1017882

You should use a generic List(Of T).

List<string> myStrings = new List<string>();
myStrings.Add("raptor");

and if you really want an array:

string[] myStringArray = myStrings.ToArray();

Wow, thanks for the fast reaction. But what is the difference between an array and a list?

@BvdL Generally speaking, a list is a collection that you can easily add/remove items to/from. An array usually has a fixed size, which is not that convenient to modify.
