Ejemplos

En el ejemplo siguiente se comprueba si el color de fondo de la consola es negro y, si es así, se cambia el color de fondo a rojo y el color de primer plano a negro.The following example checks whether the console's background color is black and, if it is, it changes the background color to red and the foreground color to black.

using System;

public class Example
{
   public static void Main()
   {
      if (Console.BackgroundColor == ConsoleColor.Black) {
         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

En el ejemplo siguiente se guardan los valores de la enumeración ConsoleColor en una matriz y se almacenan los valores actuales de las propiedades BackgroundColor y ForegroundColor en las variables.The following example saves the values of the ConsoleColor enumeration to an array and stores the current values of the BackgroundColor and ForegroundColor properties to variables. A continuación, cambia el color de primer plano para cada color de la enumeración ConsoleColor, excepto el color que coincida con el fondo actual, y cambia el color de fondo de cada color de la enumeración ConsoleColor excepto el color que coincida con el primer plano actual.It then changes the foreground color to each color in the ConsoleColor enumeration except to the color that matches the current background, and it changes the background color to each color in the ConsoleColor enumeration except to the color that matches the current foreground. (Si el color de primer plano es el mismo que el color de fondo, el texto no derá visible.) Por último, llama a al método ResetColor para restablecer los colores originale de la consola.(If the foreground color is the same as the background color, the text isn't visible.) Finally, it calls the ResetColor method to restore the original console colors.

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;
         Console.WriteLine("   The foreground color is {0}.", color);
      }
      Console.WriteLine();
      // Restore the foreground color.
      Console.ForegroundColor = currentForeground;

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

         Console.BackgroundColor = color;
         Console.WriteLine("   The background color is {0}.", color);
      }

      // Restore the original console colors.
      Console.ResetColor();
      Console.WriteLine("\nOriginal colors restored...");
   }
}
//The example displays output like the following:
//    All the foreground colors except DarkCyan, the background color:
//       The foreground color is Black.
//       The foreground color is DarkBlue.
//       The foreground color is DarkGreen.
