Nota: esta propiedad es nueva en la versión 2.0 de .NET Framework.

Obtiene o establece el color de primer plano de la consola.

Espacio de nombres: System
Ensamblado: mscorlib (en mscorlib.dll)

public static ConsoleColor ForegroundColor { get; set; }
/** @property */
public static ConsoleColor get_ForegroundColor ()

/** @property */
public static void set_ForegroundColor (ConsoleColor value)

public static function get ForegroundColor () : ConsoleColor

public static function set ForegroundColor (value : ConsoleColor)

Valor de propiedad

Una enumeración ConsoleColor que especifica el color de primer plano de la consola; es decir, el color de cada carácter que se muestra. El valor predeterminado es gris.

Tipo de excepciónCondición

ArgumentException

El color especificado en una operación de establecimiento no es un miembro válido de System.ConsoleColor.

SecurityException

El usuario no tiene permiso para realizar esta acción.

IOException

Error de E/S.

Un operación de obtención para una aplicación basada en Windows en la que no exista una consola devolverá Gray.

En el ejemplo de código siguiente se muestra la enumeración System.ConsoleColor junto con las propiedades Console.ForegroundColor y Console.BackgroundColor y el método Console.ResetColor. Se debe ejecutar el ejemplo en una consola para ver los efectos descritos de los colores.

En el ejemplo se especifican explícitamente dos constantes, Black y White, mientras que todas las demás constantes (Blue, DarkRed, etc.) se especifican indirectamente. En primer lugar se obtienen los nombres de las constantes mediante el método GetNames, que se hereda de la clase Enum. A continuación, el método Enum.Parse utiliza cada nombre para crear la constante enumerada correspondiente.

// This example demonstrates the ConsoleColor enumeration.
using System;

class Sample 
{
    public static void Main() 
    {
    String nl = Environment.NewLine;
    String[] colorNames = ConsoleColor.GetNames(typeof(ConsoleColor));

// ---------------------------------------------------------------------------------------
    Console.WriteLine("{0}All the foreground colors on a constant black background.", nl);
    Console.WriteLine("  (Black on black is not readable.){0}", nl);

    for (int x = 0; x < colorNames.Length; x++)
    {
    Console.Write("{0,2}: ", x);
    Console.BackgroundColor = ConsoleColor.Black;
    Console.ForegroundColor = (ConsoleColor)Enum.Parse(typeof(ConsoleColor), colorNames[x]);
    Console.Write("This is foreground color {0}.", colorNames[x]);
    Console.ResetColor();
    Console.WriteLine();
    }
// ---------------------------------------------------------------------------------------
    Console.WriteLine("{0}A constant white foreground on all the background colors.", nl);
    Console.WriteLine("  (White on white is not readable.){0}", nl);

    for (int x = 0; x < colorNames.Length; x++)
    {
    Console.Write("{0,2}: ", x);
    Console.ForegroundColor = ConsoleColor.White;
    Console.BackgroundColor = (ConsoleColor)Enum.Parse(typeof(ConsoleColor), colorNames[x]);
    Console.Write("This is background color {0}.", colorNames[x]);
    Console.ResetColor();
    Console.WriteLine();
    }
// ---------------------------------------------------------------------------------------
    }
}
