Convert int array to string array in C#

This post will discuss how to convert int array to string array in C#.

1. Using `Enumerable.Select` Method

LINQ’s Enumerable.Select method is commonly used to project each element of a sequence into a new form. The following code example demonstrates the usage of the Select() method for transforming an int array to a string array:

using System;

using System.Linq;

public class Example

{

public static void Main()

{

int[] numbers = { 1, 2, 3, 4, 5 };

string[] result = numbers.Select(i => i.ToString()).ToArray();

Console.WriteLine(String.Join(", ", result));

}

Output:

1, 2, 3, 4, 5

2. Using `Array.ConvertAll` Method

The standard solution to convert an array of one type to an array of another type is using the Array.ConvertAll() method. Consider the following example, which converts each element of the specified array from integer type to string type using the specified converter.

using System;

public class Example

{

public static void Main()

{

int[] numbers = { 1, 2, 3, 4, 5 };

string[] result = Array.ConvertAll(numbers, x => x.ToString());

Console.WriteLine(String.Join(", ", result));

}

Output:

1, 2, 3, 4, 5
