C Sharp Passing Array to Function

C# Passing Array to Function

We can create a function in C#, to reuse the logic of an array. Only the array name is needed to pass an array to function in C#.

Syntax:

function_name(array_name);

Example 1: Printing array elements.

using System;  
public class Example  
{  
    static void display(int[] a)  
    {  
        Console.WriteLine("Array elements:");  
        for (int i = 0; i < a.Length; i++)  
        {  
              Console.WriteLine(a[i]);  
        }  
    }  
    public static void Main(string[] args)  
    {  
        int[] a1 = { 1, 3, 5, 7, 9 };  
        int[] a2 = { 2, 4, 6, 8, 10 };  
        display(a1); //passing array to function  
        display(a2);  
    }  
}

Output:

Explanation:

In the above example, we are creating two arrays and a C# function to print the array elements of each array.

Example 2: Printing minimum number.

using System;  
public class Example  
{  
    static void Min(int[] a)  
    {  
        int min = a[0];  
        for (int i = 1; i < a.Length; i++)  
        {  
            if (min > a[i])  
            {  
                min = a[i];  
            }  
        }  
        Console.WriteLine("Minimum element is: " + min);  
    }  
    public static void Main(string[] args)  
    {  
        int[] a1 = { 3, 5, 1, 7, 9 };  
        int[] a2 = { 4, 6, 8, 10, 2 };  
        Min(a1); //passing array to function  
        Min(a2);   
    }  
}

Output:

Explanation:

In the above example, we are creating two arrays and a C# function to print the minimum number in each array.

Example 3: Printing maximum number.

using System;  
public class Example  
{  
    static void Max(int[] a)  
    {  
        int max = a[0];  
        for (int i = 1; i < a.Length; i++)  
        {  
            if (max < a[i])  
            {  
                max = a[i];  
            }  
        }  
        Console.WriteLine("Maximum element is: " + max);  
    }  
    public static void Main(string[] args)  
    {  
        int[] a1 = { 3, 5, 9, 1, 7 };  
        int[] a2 = { 4, 6, 8, 10, 2 };  
        Max(a1); //passing array to function  
        Max(a2);   
    }  
}

Output:

Explanation:

In the above example, we are creating two arrays and a C# function to print the maximum number in each array.
