Unexpected symbol `int'

First question: based on the console "Program.cs(13,16): error CS1525: Unexpected symbol `int' Compilation failed: 1 error(s), 0 warnings" which line breaks?

Second question: how do I fix my code?

Thanks : )

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");
            int counter = 0;
            var input = Console.ReadLine();
            int number;
            try {
                Int32.TryParse(times, out number)
                int times = Int32.Parse(input);
                while (counter < times) 
                {
                    Console.WriteLine("\"Yay!\"");
                    counter ++;
                }
            } catch (FormatException) {
                Console.WriteLine("You must enter a whole number.");
            }
        }
    }
}

Delete int number and Int32.TryParse(times, out number) to pass stage 1 and 2. You can declare an empty int variable but you dont need this 2 lines of code they throw the error. One reason is that you decleare the variable "times" after you using it and you already converted the string with Int32.Parse(input) to an int type :) Do you need help at task 3?

Hey,

I don't think Int32.TryParse(times, out number) is working. Also, could you explain why you wrote out number but never state what number is?

in my opinion

1st CATCH is wrong you have to add ref on your exception to CALL error patch or description - catch (FormatException e)

2nd you cant use empty value "number"; for example give him value 0 at the start

3rd static void Main(string[] args) its RULE
