C# Storing value in Array

After declaration of array, you need to store value in array. Either you can store value at compile time by writing in the program or run time by taking input from the user. In this chapter, we will learn how to store value in array.

Storing value directly in your C# program:

Inline:

int[] arr =new int[5] { 1, 2, 3, 4, 5 };

Index:

 int[] arr = new int[5]
      arr[0] = 1;
      arr[1] = 2;
      arr[2] = 3;
      arr[3] = 4;
      arr[4] = 5;

if you are storing value in array by taking users input, then you can use loop to accept value in array. The following C# example will focus how to get input from users at runtime and store in an array.

C# programming example about how to store value in array:  

---

using System;

namespace store_value_in_array
{
  class Program
   {
     static void Main(string[] args)
      {
        int i;
        int[] arr = new int[5]; // 5 size array
           
        // Accepting value from user 
        for (i = 0; i < 5; i++)
         {
           Console.Write("\nEnter your number:\t");
           //Storing value in an array
           arr[i] = Convert.ToInt32(Console.ReadLine());
         }

        Console.WriteLine("\n\n");
        //Printing the value on console
        for (i = 0; i < 5; i++)
         {
           Console.WriteLine("you entered {0}", arr[i]);
         }
        Console.ReadLine();
      }
   }
}

In the preceding example we declared an array named arr. After that using for loop, we traversed each index position of array and stored value.

Output

---

   
Enter your number:       7
Enter your number:       3
Enter your number:       5
Enter your number:       6
Enter your number:       8


you entered 7
you entered 3
you entered 5
you entered 6
you entered 8
