Convert int array to string in C#

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

1. Using `String.Join` Method

The String.Join method can be used to concatenate elements of the specified array using the specified separator between each element.

The following example shows how to use String.Join to convert an integer array to a comma-delimited string in C#.

using System;

public class Example

{

public static void Main()

{

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

string s = String.Join(", ", array);

Console.WriteLine(s); // 1, 2, 3, 4, 5

}

2. Using `Array.ForEach` Method

If you just need to join together all elements of an array without any separator, you can append each element of the array to a StringBuilder instance using the Array.ForEach method.

using System;

using System.Text;

public class Example

{

public static void Main()

{

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

var builder = new StringBuilder();

Array.ForEach(array, x => builder.Append(x));

string s = builder.ToString();

Console.WriteLine(s); // 12345

}

3. Using `Enumerable.Aggregate` Method

Finally, you can apply an accumulator function over the given integer array sequence with a specified seed as the initial accumulator value. Here’s what the code would look like:

using System;

using System.Linq;

public class Example

{

public static void Main()

{

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

string s = array.Aggregate(string.Empty, (s, i) => s + i);

Console.WriteLine(s); // 12345

}
