C# Passing Array to Function

In C#, to reuse the array logic, we can create function. To pass array to function in C#, we need to provide only array name.

C# Passing Array to Function Example: print array elements

Let's see an example of C# function which prints the array elements.

using System;
public class ArrayExample
{
    static void printArray(int[] arr)
    {
        Console.WriteLine("Printing array elements:");
        for (int i = 0; i < arr.Length; i++)
        {
              Console.WriteLine(arr[i]);
        }
    }
    public static void Main(string[] args)
    {
        int[] arr1 = { 25, 10, 20, 15, 40, 50 };
        int[] arr2 = { 12, 23, 44, 11, 54 };
        printArray(arr1);//passing array to function
        printArray(arr2);
    }
}

Output:

Printing array elements:
25
10
20
15
40
50
Printing array elements:
12
23
44
11
54

C# Passing Array to Function Example: Print minimum number

Let's see an example of C# array which prints minimum number in an array using function.

using System;
public class ArrayExample
{
    static void printMin(int[] arr)
    {
        int min = arr[0];
        for (int i = 1; i < arr.Length; i++)
        {
            if (min > arr[i])
            {
                min = arr[i];
            }
        }
        Console.WriteLine("Minimum element is: " + min);
    }
    public static void Main(string[] args)
    {
        int[] arr1 = { 25, 10, 20, 15, 40, 50 };
        int[] arr2 = { 12, 23, 44, 11, 54 };

        printMin(arr1);//passing array to function
        printMin(arr2);
    }
}

Output:

Minimum element is: 10
Minimum element is: 11

C# Passing Array to Function Example: Print maximum number

Let's see an example of C# array which prints maximum number in an array using function.

using System;
public class ArrayExample
{
    static void printMax(int[] arr)
    {
        int max = arr[0];
        for (int i = 1; i < arr.Length; i++)
        {
            if (max < arr[i])
            {
                max = arr[i];
            }
        }
        Console.WriteLine("Maximum element is: " + max);
    }
    public static void Main(string[] args)
    {
        int[] arr1 = { 25, 10, 20, 15, 40, 50 };
        int[] arr2 = { 12, 23, 64, 11, 54 };

        printMax(arr1);//passing array to function
        printMax(arr2);
    }
}

Output:

Maximum element is: 50
Maximum element is: 64
