Define a Single-Dimensional Array in C#

An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type stored at contiguous memory locations.

To define a single-dimensional array −

int[] runs = new int[10];

Let us now initialize the array in the same line −

int[] runs = new int[5] {125, 173, 190, 264, 188};

The following is an example displaying how to declare, initialize and display an array −

Example

 Live Demo

using System;

namespace Program {
   class Demo {
      static void Main(string[] args) {
         int[] runs = new int[5] {125, 173, 190, 264, 188};
         int i,j;
         for (j = 0; j < 5; j++ ) {
            Console.WriteLine("Innings score of Cricketer[{0}] = {1}", j, runs[j]);
         }
         Console.ReadKey();
      }
   }
}

Output

Innings score of Cricketer[0] = 125
Innings score of Cricketer[1] = 173
Innings score of Cricketer[2] = 190
Innings score of Cricketer[3] = 264
Innings score of Cricketer[4] = 188
