In C#, there are multiple ways to declare and initialize an empty array. We will learn a few of them in this blog.

• Using T[] array = {}
• Using T[] array = new T[] {}
• Using T[] array = new T[0]

Using T[] array = {}

using System;

namespace EmptyArray
{
    class Program
    {
        public static void Main()
        {
            string[] array = {  };

            Console.WriteLine(array.Length);
            Console.ReadKey();
        }
    }
}

Output:

0

Using T[] array = new T[] {}

using System;

namespace EmptyArray
{
    class Program
    {
        public static void Main()
        {
            string[] array = new string[] { };

            Console.WriteLine(array.Length);
            Console.ReadKey();
        }
    }
}

 Output:

0

Using T[] array = new T[0]

using System;

namespace EmptyArray
{
    class Program
    {
        public static void Main()
        {
            string[] array = new string[0];

            Console.WriteLine(array.Length);
            Console.ReadKey();
        }
    }
}

  Output:

0
