How do a loop this program? Learning CSharp

Hi,

I'm learning C# and trying to write the program below, everything
works fine until the last section:

Console.Write("Would you like to play again y/n: ");
            again = Console.ReadLine();

            if (again.ToLower() == "y")
            {
            ????
            }
            else
                Console.WriteLine("GoodBye");

How do I loop the program to start again, I tried copying the whole
program into the if statement but this doesn't work any ideas?

        static void Main(string[] args)
        {

                Random generator = new Random();
                int RandomNumber = generator.Next(1,100);
                int score = 1;
                int Guess = 0;
                string again;

            while (Guess != RandomNumber)
            {
                Console.Write("Guess a number from 1 to 100: ");
                Guess = Convert.ToInt32(Console.ReadLine());

                if (Guess == RandomNumber)
                    Console.WriteLine("Your Correct. It took you " + score + "
Tries");
                else if( Guess > RandomNumber)
                    Console.WriteLine("To High");
                else Console.WriteLine("To Low");
                score++;

            }

            Console.Write("Would you like to play again y/n: ");
            again = Console.ReadLine();

            if (again.ToLower() == "y")
            {
            ????
            }
            else
                Console.WriteLine("GoodBye");

        }
    }
}

You could wrap the whole thing in a infinite loop, and then breaking
the loop when you want to exit.

Something like:

while (true)
{
    //Your other code here

    Console.Write("Would you like to play again y/n: ");
    again = Console.ReadLine();

    if (again.ToLower() != "y")
    {
        Console.WriteLine("GoodBye");
        break;
    }
}

Well, you want to play *while* the user is interested, right...
Does that give you enough of a hint?
