Time Countdown in Console Application

using System;
using System.Timers;
namespace Prog4
{
class program
{
private static int _countDown = 30; // Seconds
private static bool waySelected = false;
static void OnTimedEvent(object source, ElapsedEventArgs e)
{
if (waySelected == false)
{
if (_countDown-- <= 0)
Console.WriteLine("You got crushed!");
else
{
Console.SetCursorPosition(0, 9);
Console.WriteLine(_countDown + " seconds until you are crushed");
}
}
}
static void Main(string[] args)
{
Timer aTimer = new Timer(1000);
aTimer.Elapsed += OnTimedEvent;
aTimer.Enabled = true;
Random random = new Random();
int north = random.Next(1, 5);
int south = random.Next(1, 5);
int east = random.Next(1, 5);
int west = random.Next(1, 5);
Console.WriteLine("You are in a room that is slowly closing in on you, it has only four exits.\n" +
"The four exits face: North, South, East and West. \n" +
"Press n for North, \n" +
" s for South, \n" +
" e for East, \n" +
" w for West, \n" +
"Only one exit leads to outside, the rest lead to certain doooooooooooooom \n");
Console.WriteLine("Press any key to continue...");
ConsoleKeyInfo way = Console.ReadKey(true);
waySelected = true;
Console.Clear();
switch (way.KeyChar)
{
case 'n':
Console.WriteLine("The Next room is looks like North ...");
break;
case 's':
Console.WriteLine("The Next room is looks like South ...");
break;
case 'e':
Console.WriteLine("The Next room is looks like East ...");
break;
case 'w':
Console.WriteLine("The Next room is looks like West ...");
break;
default:
Console.WriteLine("You choose wrong way, you got crushed!");
break;
}
Console.ReadKey(true);
}
}

There are two ways i know of doing what you want

1) Use Console.SetCursorPosition();. This is applicable when you are sure of the amount of characters that will be above the timer.

2) Use Console.CursorLeft. This is applicable in all cases.

static void Main(string[] args)
{
for (int a = 10; a >= 0; a--)
{
Console.SetCursorPosition(0,2);
Console.Write("Generating Preview in {0} ", a); // Override complete previous contents
System.Threading.Thread.Sleep(1000);
}
}
static void Main(string[] args)
{
Console.Write("Generating Preview in ");
for (int a = 10; a >= 0; a--)
{
Console.CursorLeft = 22;
Console.Write("{0} ", a ); // Add space to make sure to override previous contents
System.Threading.Thread.Sleep(1000);
}
