Exemplos

O exemplo seguinte demonstra o uso de um ConsoleKeyInfo objeto numa operação de leitura.

using System;

class Example
{
   public static void Main()
   {
      ConsoleKeyInfo cki;
      // Prevent example from ending if CTL+C is pressed.
      Console.TreatControlCAsInput = true;

      Console.WriteLine("Press any combination of CTL, ALT, and SHIFT, and a console key.");
      Console.WriteLine("Press the Escape (Esc) key to quit: \n");
      do
      {
         cki = Console.ReadKey();
         Console.Write(" --- You pressed ");
         if((cki.Modifiers & ConsoleModifiers.Alt) != 0) Console.Write("ALT+");

Observações

O ConsoleKeyInfo tipo não se destina a ser criado pelos utilizadores. Em vez disso, é devolvido ao utilizador em resposta à chamada do Console.ReadKey método.

O ConsoleKeyInfo objeto descreve a constante e o ConsoleKey carácter Unicode, se existirem, que correspondem à tecla de consola pressionada. O ConsoleKeyInfo objeto também descreve, numa combinação bit a bit de ConsoleModifiers valores, se uma ou mais teclas modificadoras SHIFT, ALT ou CTRL foi pressionada simultaneamente com a tecla da consola.
