Valor de Propriedade

ConsoleColor

A ConsoleColor que especifica a cor em primeiro plano da consola; ou seja, a cor de cada carácter que é exibido. O padrão é cinza.

Atributos
UnsupportedOSPlatformAttribute

Exceções

ArgumentException

A cor especificada numa operação de conjunto não é um membro válido de ConsoleColor.

SecurityException

O usuário não tem permissão para executar essa ação.

IOException

Ocorreu um erro de I/O.

Exemplos

O exemplo seguinte verifica se a cor de fundo da consola é preta e, se for, muda a cor de fundo para vermelho e a cor de primeiro plano para preto.

using System;

public class Example
{
   public static void Main()
   {
      if (Console.BackgroundColor == ConsoleColor.Black) {
         Console.BackgroundColor = ConsoleColor.Red;
         Console.ForegroundColor = ConsoleColor.Black;
         Console.Clear();
      }
   }
}

open System

if Console.BackgroundColor = ConsoleColor.Black then
    Console.BackgroundColor <- ConsoleColor.Red
    Console.ForegroundColor <- ConsoleColor.Black
    Console.Clear()

Module Example
   Public Sub Main()
      If Console.BackgroundColor = ConsoleColor.Black Then
         Console.BackgroundColor = ConsoleColor.Red
         Console.ForegroundColor = ConsoleColor.Black
         Console.Clear()
      End If
   End Sub
End Module

O exemplo seguinte guarda os valores da ConsoleColor enumeração num array e armazena os valores atuais das BackgroundColor propriedades e ForegroundColor para variáveis. Depois, altera a cor do primeiro plano para cada cor da ConsoleColor enumeração, exceto para a cor que corresponde ao fundo atual, e altera a cor de fundo para cada cor da ConsoleColor enumeração, exceto para a cor que corresponde ao primeiro plano atual. (Se a cor do primeiro plano for igual à cor de fundo, o texto não é visível.) Finalmente, chama o ResetColor método para restaurar as cores originais da consola.

using System;

class Example
{
   public static void Main()
   {
      // Get an array with the values of ConsoleColor enumeration members.
      ConsoleColor[] colors = (ConsoleColor[]) ConsoleColor.GetValues(typeof(ConsoleColor));
      // Save the current background and foreground colors.
      ConsoleColor currentBackground = Console.BackgroundColor;
      ConsoleColor currentForeground = Console.ForegroundColor;

      // Display all foreground colors except the one that matches the background.
      Console.WriteLine("All the foreground colors except {0}, the background color:",
                        currentBackground);
      foreach (var color in colors) {
         if (color == currentBackground) continue;

         Console.ForegroundColor = color;

Observações

Uma operação get para uma aplicação baseada em Windows, na qual não existe uma consola, devolve Gray. Os sistemas Unix não fornecem qualquer mecanismo geral para obter as cores atuais da consola. Por causa disso, ForegroundColor retorna (ConsoleColor)-1 até ser definido de forma explícita (usando o setter).
