System.Random does not contain definition....C#?

Question

I've spent nearly an hour on this error and I can't seem to find where I went wrong (fresh set of eyes would probably help lol). it's the {array = Random.genRandom();} I'm also getting The name rand doesn't exist in the context for my MainClass. where it says ' and also getting an error for my contructor I'm basically just making a random number generator game where the number is displayed at the beginning and the person can get a strike, ball, etc.. for wrong answers. I have two classes. A Main class and a sub-class.

MainClass:

using System; 
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace NumBaseBall
{
    class MainClass
    {
        static void Main(string[] args)
        {
            int[] player;
            int[] array;
            int NumberOfTries = 0;
            int Strikes = 0;
            int ball = 0;
            int input;
            int count = 0;
            int g = 0;
            decimal game = 0;
            decimal wins = 0;
            decimal percent = 0;
            int Ru = 0;



            Console.WriteLine("Welcome to Number Baseball Game");
            Console.WriteLine("By: ");


            while (Ru != -1)
            {
                Console.WriteLine("The three Digit random number is: \t");

                MethodClass = rand = new MethodClass();

                array = Random.genRandom();
                Console.WriteLine();

                NumberOfTries = 0;

                game++;

                while (NumberOfTries < 5)
                {

                    ball = 0;
                    Strikes = 0;

                    Console.Write("Enter three digit number: \t");
                    input = Convert.ToInt32(Console.ReadLine());

                    player = MethodClass.splitNumber(input);

                    {

                        if ((player[i] == array[g]) && (count == 0))
                        {

Please read [this](https://stackoverflow.com/help/mcve) and try trimming your code to a smaller example that reproduces the issue. In doing so you'll likely solve the problem for yourself. — Preston Guillot, Feb 14 '16 at 00:53
Use [`int.TryParse()`](http://stackoverflow.com/a/199484/380384) to ensure smooth flow of the program, after you check for `ENTER`. — John Alexiou, Feb 14 '16 at 01:19

Try changing this:

MethodClass = rand = new MethodClass();

array = Random.genRandom();

to:

MethodClass  rand = new MethodClass();

array = rand.genRandom();

Hey just a quick question: I want a prompt at the end where when a player hits 0 the game restarts and when they hit enter, it terminates. Here's what I have: `Console.Write("To continue playing, hit 0: To exit the game hit enter. To continue enter any number other than -1 : ");` – JavaStudent22 Feb 14 '16 at 01:06
I know I can use the `Convert.ToInt32` for the 0 but what about when they hit ENTER to exit? – JavaStudent22 Feb 14 '16 at 01:08
