|C#| Как объединить два массива с исключением повторяющихся значений?

[Alexander333]

Помогите пожалуйста, никак не могу объединить два массива с исключением повторяющихся значений.

Вот код:

using System;
using System.Collections.Generic;  
using System.Linq;  
using System.Text;  
using System.Threading.Tasks;  
using System.Diagnostics;
 
 
namespace Task
{
 
    class Program
    {
        
        
        static void Main(string[] args)
        {
            
            Console.WriteLine("Press <enter> to start...");
            Console.Read();
            Console.Clear();
            Menu();
        }
        
 
        public static void Menu()
        {
            
            char command;
            char choice;
            
            do
            {
                Console.WriteLine("Menu of commands");
                Console.WriteLine("1. Generate elements of a one-dimensional array. Concatenate two arrays.");
                Console.WriteLine("2. Find prime numbers and concatenate arrays.");
                Console.WriteLine("3. Exit.");
               
 
                command = (char)Console.Read(); 
                Console.ReadLine();

int[] mas1 = new int[]{1,2,3};
int[] mas2 = new int[]{2,4,4};

// избавить от дубликатов
int[] mas3 = mas1.Concat(mas2).Distinct().ToArray();

// избавить от элементов имеющих дубликаты
int[] mas4 = mas1.Concat(mas2).GroupBy(s => s).Where(p => p.Count() == 1).Select(l => l.Key).ToArray();
