What am I doing wrong I give up.

using System;

namespace Treehouse.CodeChallenges { class Program { static void Main() { Console.Write("Enter the number of times to print \"Yay!\": ");

        try {
          int numberOfTimes = int.Parse(Console.ReadLine());

          if (numberOfTimes >= 0) {
            for (int i=0; i<numberOfTimes; i++) {
              Console.WriteLine("\"Yay!\"");
            } else {
              Console.Write("You must enter a positive number.");
            }
          else {}
        } catch (FormatException) {
          Console.Write("You must enter a whole number.");
        }
    }
}

}

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");

            try {
              int numberOfTimes = int.Parse(Console.ReadLine());

              if (numberOfTimes >= 0) {
                for (int i=0; i<numberOfTimes; i++) {
                  Console.WriteLine("\"Yay!\"");
                } else {
                  Console.Write("You must enter a positive number.");
                }
              else {}
            } catch (FormatException) {
              Console.Write("You must enter a whole number.");
            }
        }
    }
}

if (numberOfTimes >= 0) {
  for (int i=0; i<numberOfTimes; i++) {
    Console.WriteLine("\"Yay!\"");
  } else { // <-- You are missing a closing brace for the `if` statement
    Console.Write("You must enter a positive number.");
  }
else {} // <-- This `else` statement is redundant and not connected to any `if` statement.

If you add the closing brace, remove the redundant else and clean up the formatting a bit like this:

using System;

namespace Treehouse.CodeChallenges
{
    class Program
    {
        static void Main()
        {
            Console.Write("Enter the number of times to print \"Yay!\": ");

            try {
              int numberOfTimes = int.Parse(Console.ReadLine());

              if (numberOfTimes >= 0) {
                for (int i=0; i<numberOfTimes; i++) {
                  Console.WriteLine("\"Yay!\"");
                }
              } else { // <-- Added mising closing brace
                Console.Write("You must enter a positive number.");
              }
              // Removed redundant else statement

            } catch (FormatException) {
              Console.Write("You must enter a whole number.");
            }
        }
    }
}

Then your code will work.
