Hiding console input

[radarmy]

I'm working on a console application where you have to enter in a username and password for a database and I was hoping to make it so when the user enters their password in, it isn't visible in the console window.

I think I can figure out how to do it but the problem is I'm not sure how to capture each and every individual key. So then if I could do that, if the key was something other than enter, it would add it to a string and then write back: \b\0\b to erase it.

So my question is, how can I capture each key?

using System;
using System.Text;

class a
{
	Console.Write("Input a password: ");
	StringBuilder sb = new StringBuilder();
	while (true)
	{

		ConsoleKeyInfo cki = Console.ReadKey(true);
		if (cki.Key == ConsoleKey.Enter)
		{
			Console.WriteLine();
			break;
		}
		
		if (cki.Key == ConsoleKey.BackSpace)
		{
			if (sb.Length > 0)
			{
				Console.Write("\b\0\b");
				sb.Length--;
			}
			
			continue;
		}
		
		Console.Write('*');
		sb.Append(cki.KeyChar);
	}

	Console.WriteLine("Your password is: {0}", sb.ToString());
}

that may help you.

I've seen that code snippet floating around the WWW but I think you need Whidbey to use it...
