Get string[] elements with index of int[] indices

Question

I have a string[], and want to get the elements of the string[] that has an index, of which i know exist, specified in an int[].

string[] stringArray = { "a", "b", "c", "d", "e", "f", "g" };
int[] indices = { 1, 2, 4, 6 };

From this, I am trying to get a string[] containing { "b", "c", "e", "g" }. Preferably using a lambda expression. How would I do this?

Answer 1

indices.Select(i => stringArray[i]);

Answer 2

One way you can do it is like this.

string[] result = indices.Select(i => stringArray[i]).ToArray()
