How to Join an Int Array as a String Array

Question

How to Join an Int Array as a String Array

Ex: {0, 1, 2, 3, 4, 5}   -->  "0 1 2 3 4 5"

Answer 1

The example you show turns an int array into a string, not a string array. To do that something like this would work:

string s = intArray[0];
for (int i = 1; i < intArray.Length; i++)
{
   s += " " + intArray[i];
}

To turn it into a string array:

int[] intArray = new [] {0, 1 ,2 ,3 ,4, 5};
string[] s = new string[intArray.Length];
for (int i = 0; i < s.Length; i++)
{
   s[i] = intArray[i].ToString();
}

Answer 2

Sorry, I saw this post first in the "C# Language" forum, and answered a slightly different approach using stringwriter.

Answer 3

Try to "convert" from int[] to string[] :

 

string[] strArray = Array.ConvertAll(intArray, n => n.ToString());

Hi Mitja,

You're right. To get the expected "0 1 2 3 4 5", you also will have to join the string array to a string:

int[] intArray = new[] { 1, 2, 3, 4, 5 };
string[] strArray = Array.ConvertAll(intArray, i => i.ToString());
string numberString = String.Join(" ", strArray);
