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("
Press 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 −
