How to exit a console application without requiring enter

What would be the best way to exit an application when a user types x without having to hit enter. The current code I am using is this:

Console.WriteLine("\nType x to exit > ");
string test = Console.ReadLine();
while (test != "x")
{
    Console.WriteLine("\nType x to exit > ");
    test = Console.ReadLine();
}

This will make the user experience better.

You could do something like this:

do
{
    Console.WriteLine("\nType x to exit > ");
}
while (Console.ReadKey().KeyChar != 'x');

Console.ReadKey() let you read a single key press. Console.readLine() is waiting for a line termination. Here's the doc for reference:

You can read the first character and then if it's not "x", read a line input (and prepend the first char received before).

You can use Console.ReadKey instead.

Obtains the next character or function key pressed by the user. The pressed key is optionally displayed in the console window.
