What are all the possible C# array initialization syntaxes?\\n

Array can be initialized in more than one ways in C#. Let us see some example.

Method One

Using size of array.

int [] marks = new int[5] { 99, 98, 92, 97, 95};

Method Two

By omitting the size.

int [] marks = new int[] { 99, 98, 92, 97, 95};

Method Three

Initializing at the time of declaration.

int [] marks = { 99, 98, 92, 97, 95};

Let us see one of the ways to initialize arrays in C#.

Example

 Live Demo

using System; namespace Demo {    class MyArray {       static void Main(string[] args) {          int [] n = new int[10]; /* n is an array of 10 integers */          int i,j;          /* initialize elements of array n */          for ( i = 0; i < 10; i++ ) {             n[ i ] = i + 100;          }          /* output each array element's value */          for (j = 0; j < 10; j++ ) {             Console.WriteLine("Element[{0}] = {1}", j, n[j]);          }          Console.ReadKey();       }    } }

Output

Element[0] = 100 Element[1] = 101 Element[2] = 102 Element[3] = 103 Element[4] = 104 Element[5] = 105 Element[6] = 106 Element[7] = 107 Element[8] = 108 Element[9] = 109
