Console.KeyAvailable() Property in C#

The Console.KeyAvailable() property in C# is used to get a value indicating whether a key press is available in the input stream.

Syntax

The syntax is as follows −

public static bool KeyAvailable { get; }

Example

Let us now see an example to implement the Console.KeyAvailable() property in C# −

using System;
using System.Threading;
class Demo {
   public static void Main (string[] args) {
      ConsoleKeyInfo cs = new ConsoleKeyInfo();
      do {
         Console.WriteLine("\nPress a key to display; "+ "press the 'Q' key to quit.");
         while (Console.KeyAvailable == false)Thread.Sleep(100);
         cs = Console.ReadKey(true);
         Console.WriteLine("You pressed the '{0}' key.", cs.Key);
      }
       while (cs.Key != ConsoleKey.Q);
   }
}

Output

This will produce the following output −
