Use foreach Statement for Accessing Array Elements in C#

To access Array elements in a foreach statement, use the numeric index.

Let’s say the following is our code.

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 */
         /* initialize elements of array n */
         for ( int i = 0; i < 10; i++ ) {
            n[i] = i + 100;
         }
         /* output each array element's value */
         foreach (int j in n ) {
            int i = j-100;
            Console.WriteLine("Element[{0}] = {1}", i, j);
         }
         Console.WriteLine(n);
         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
System.Int32[]

Now let’s say you need the second element. For that, use.

int a = n[1];

The above will give the second element i.e. 101.
