Values ​​are not selected randomly from 2 arrays, how to fix?

Question

C++ / C#

There are 2 arrays from which values ​​should be selected randomly. However, the index of a value from one array always matches an index from another array. What needs to be done so that the indexes of the elements from each array are different?

using System;

namespace Example
{
    class Program
    {
        static void Main(string[] args)
        {
            Start: string[] name = new string[10]
               {
                            "имя1",
                            "имя2",
                            "имя3",
                            "имя4",
                            "имя5",
                            "имя6",
                            "имя7",
                            "имя8",
                            "имя9",
                            "имя10"
               };
            Random rand_name = new Random();
            int index_n = rand_name.Next(name.Length);
            string n = name[index_n];

            string[] name2 = new string[10]
            {
                            "фамилия1",
                            "фамилия2",
                            "фамилия3",
                            "фамилия4",
                            "фамилия5",
                            "фамилия6",
                            "фамилия7",
                            "фамилия8",
                            "фамилия9",
                            "фамилия10"
            };
            Random rand_name2 = new Random();
            int index_n2 = rand_name2.Next(name2.Length);
            string n2 = name2[index_n2];
            Console.WriteLine($"{n} {n2}");
            Console.ReadKey(); 
            goto Start;
        }
    }
}

Thank you!

Since the numbers are not random, but pseudo-random, a certain seed is used to generate them, which is the same within one calculation cycle. The solution is not to create a second instance of Random, but to use the previous one: int index_n2 = rand_name.Next(name2.Length);
PS Don't use goto, it's bad practice in C#
