How is an array declared in C#?

CsharpProgrammingServer Side Programming

To declare an array in C#, you can use the following syntax −

datatype[ ] Name_of_array;

Here,

  • datatype is used to specify the type of elements in the array.

  • [ ] specifies the size of the array.

  • Name_of_array specifies the name of the array.

The following is an example −

double[ ] balance;

Let us see an example in which an array is declared and values are added to it −

Example

 Live Demo

using System;

namespace ArrayApplication {
   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
