How to get difference between two array without using linq or Set operator using csharp ?

How to get difference between two array without using linq or Set operator using csharp ?

(OP)
I work on csharp
I have two arrays of string

A1 = [Watermelon, Apple, Mango, Guava, Banana]
A2 = [Orange, Kiwi, Apple, Watermelon]

i need to write code by csharp get difference between two arrays
and display difference between two arrays but without using linq or set operator

expected result
Mango
Guava
Orange
Kiwi

RE: How to get difference between two array without using linq or Set operator using csharp ?

Banana should be in expected result too

What have you tried so far ?

RE: How to get difference between two array without using linq or Set operator using csharp ?

(OP)
i tried and reached to result by linq

var array1 = new[] { "Watermelon", "Apple", "Mango", "Guava", "Banana" };
var array2 = new[] { "Orange", "Kiwi", "Apple", "Watermelon" };

var result = array2.Except(array1).Concat(array1.Except(array2));

but i need it to get result without using linq or set operator

RE: How to get difference between two array without using linq or Set operator using csharp ?

Simply something like this should work:
iterate over first array and check every element if it is in the second array too - and if not then this is the different element.
Then do the same with the second array.

I tried what I described before:

CODE

using System;

class Program
{
	public static void Main(string[] args)
	{
		string[] a = {"Watermelon", "Apple", "Mango", "Guava", "Banana"};
		string[] b = {"Orange", "Kiwi", "Apple", "Watermelon"};

		Console.WriteLine("Differences:\n");	
		int numDiff = arrayDifference(a, b);
		string diffResult = numDiff == 0 ? "There are no differences" : "Number of differences found: " + numDiff;
		Console.WriteLine("\n" + diffResult + "\n");
		
		Console.Write("Press any key to continue . . . ");
		Console.ReadKey(true);
	}
	
	static int arrayDifference(string[] x, string[] y) {
		int numberOfDifferentElements = 0;
		
		foreach(string s in x) {
			if (Array.IndexOf(y, s) == -1) {
				Console.WriteLine(s);
				numberOfDifferentElements++;
			}
		}
		
		foreach(string s in y) {
			if (Array.IndexOf(x, s) == -1) {
				Console.WriteLine(s);
				numberOfDifferentElements++;
			}
		}
		
		return numberOfDifferentElements;
	}
}

Output:

CODE

Differences:

Mango
Guava
Banana
Orange
Kiwi

Number of differences found: 5

Press any key to continue . . .
