How to declare an array in C#?

CsharpProgrammingServer Side Programming

An array is used to store a collection of data. It stores a fixed-size sequential collection of elements of the same type.

To declare an array, follow the below given syntax −

datatype[] arrayName;

Here,

  • datatype is used to specify the type of elements in the array.
  • [ ] sets the rank of the array. The rank specifies the size of the array.
  • arrayName specifies the name of the array.

Let us now see an example −

int[] goals;

The following is an example showing how to declare and initialize arrays in C#.

Example

 Live Demo

using System;

namespace Demo {
   class MyArray {
      static void Main(string[] args) {
         int [] goals = new int[5] {3,2,1,5,4};
         int i,j;

         for (j = 0; j < 5; j++ ) {
            Console.WriteLine("Goals in FIFA - Match[{0}] = {1}", j, goals[j]);
         }
         Console.ReadKey();
      }
   }
}

Output

Goals in FIFA - Match[0] = 3
Goals in FIFA - Match[1] = 2
Goals in FIFA - Match[2] = 1
Goals in FIFA - Match[3] = 5
Goals in FIFA - Match[4] = 4
