class Program
{
    static string months[] = { "January", "February", "March", "April", ...
    static string suffixes[] = { "st", "nd", "rd", "th", ...
    static void Main(string[] args)
    {
        int monthNumber = 0;

        //Prompt for number
        while (monthNumber == 0)
        {
            Console.Write("Enter a number between 1 and 12");
            if (!int.TryParse(Console.ReadLine(), monthNumber)
                monthNumber = 0;
        }
        Console.WriteLine(string.Format("This is the {0}{1} month...{2}", monthNumber, suffixes[monthNumber-1], months[monthNumber-1]));
    }
}

if (monthNumber == 1)
{
    Console.Write("This is the 1st month...January");
}
else if (monthNumber == 2)
{
    Console.Write("This is the 2nd month...February");
}
else if (monthNumber == 3)
{
    Console.Write("This is the 3rd month...March");
}
else if // and so on..
