Passing Array to Function in C#

A function can receive a parameter. Similarly a function can also receive an array. We can pass an array as parameter to function. In this activity, when we pass an array to a function we actually passes a reference to the array. we give permission to a function that it can access and can modify the elements of the array.

Passing Array to Function in C# with Example

using System;
public class Program
{
  public static void Main(string[] arge)
  {
    double[] prices = { 8.52, 6.34, 12.00, 9.31, 16.89 };

    // Pass the 'numbers' array to a function
    MangoPrices(prices);

    // Check if the array has been modified
    Console.WriteLine("After function call:");

    foreach (double price in prices)
    {
      Console.WriteLine("Price Of Mango = {0}", price);
    }
  }

  static void MangoPrices(double[] arrPrice)
  {
    // A array with name of 'reprice' can access and modify here.
    for (int q = 0; q < arrPrice.Length; q++)
    {
      arrPrice[q] *= 2; // Double each element of the array
    }
  }
}

Output

After function call:
Price Of Mango = 17.04
Price Of Mango = 12.68
Price Of Mango = 24.00
Price Of Mango = 18.62
Price Of Mango = 33.78
