I am having trouble using the try and catch method. Error: 'x' does not exist in the current context

Here is my code

try{ int x = int.Parse(Console.ReadLine()); } catch(FormatException){ }

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {

            int a = 0;

            Console.Write("Enter the number of times to print \"Yay!\": ");

            try{
                int x = int.Parse(Console.ReadLine());
            }
            catch(FormatException){
            }
            Console.WriteLine(x);

            while (a < x)
            {

                Console.WriteLine("Yay!");
                a++;

            }

                Console.ReadLine();

            }

    }
}

That is because the try's block has its own scope. If you declare a local variable there, that will be only accessible within that block and in its child blocks.

There are more than one solutions. You can pull out the x declaration, or you can take the while loop in, for example.
