Declare and initialize an empty array in C#

This post will discuss how to declare and initialize an empty array in C#.

There are several ways to declare and initialize an empty array in C#. Some of them are demonstrated below:

1. T[] array = new T[] {}

using System;

public class Example

{

public static void Main()

{

int[] array = new int[] {};

Console.WriteLine(array.Length);

}

2. T[] array = new T[0]

using System;

public class Example

{

public static void Main()

{

int[] array = new int[0];

Console.WriteLine(array.Length);

}

3. T[] array = {}

using System;

public class Example

{

public static void Main()

{

int[] array = {};

Console.WriteLine(array.Length);

}

4. T[] array = Array.Empty<T>()

using System;

public class Example

{

public static void Main()

{

int[] array = Array.Empty<int>();

Console.WriteLine(array.Length);

}

5. T[] array = Enumerable.Empty<T>().ToArray()

using System;

using System.Linq;

public class Example

{

public static void Main()

{

int[] array = Enumerable.Empty<int>().ToArray();

Console.WriteLine(array.Length);

}

Download Run Code

6. T[] array = Enumerable.Repeat(0, 0).ToArray()

using System;

using System.Linq;

public class Example

{

public static void Main()

{

int[] array = Enumerable.Repeat(0, 0).ToArray();

Console.WriteLine(array.Length);

}
