How to take nth item in array to zth item in array?

Question

I created an array like this:

string[] test = new string[]{"apple", "banana", "tomato", "pineapple", "grapes"};

And now, I would like to take the 2nd, 3rd and the 4th item in the array and join together, currently I'm using this code:

string result = "";
for(int i = 1; i < 4; i++)
{
    result += test[i] + " ";
}

So the result would be banana tomato pineapple and this works fine.

And I would like to ask if there's a standard or better way to achieve this?

Answer 1

You can write it more succinctly like this:

string result = string.Join(" ", test.Skip(1).Take(3));

Also, this has the bonus of not adding a trailing space (which your code does).

Answer 2

Another option, which uses GetRange, which is very natural for this:

var result = String.Join(" ", test.ToList().GetRange(1, 3));
