Enumerazione ConsoleColor

Nota: questa enumerazione è stata introdotta con .NET Framework versione 2.0.

Specifica le costanti per la definizione dei colori dello sfondo e in primo piano della console.

Spazio dei nomi: System
Assembly: mscorlib (in mscorlib.dll)

[SerializableAttribute] 
public enum ConsoleColor
/** @attribute SerializableAttribute() */ 
public enum ConsoleColor
SerializableAttribute 
public enum ConsoleColor

 Nome membroDescrizione
BlackIl colore nero. 
BlueIl colore blu. 
CyanIl colore ciano (verde-blu). 
DarkBlueIl colore blu scuro. 
DarkCyanIl colore ciano scuro (verde-blu scuro). 
DarkGrayIl colore grigio scuro. 
DarkGreenIl colore verde scuro. 
DarkMagentaIl colore magenta scuro (rosso porpora scuro). 
DarkRedIl colore rosso scuro. 
DarkYellowIl colore giallo scuro (ocra). 
GrayIl colore grigio. 
GreenIl colore verde. 
MagentaIl colore magenta (rosso porpora). 
RedIl colore rosso. 
WhiteIl colore bianco 
YellowIl colore giallo. 

Nell'esempio di codice riportato di seguito viene illustrata l'enumerazione System.ConsoleColor insieme alle proprietà Console.ForegroundColor, Console.BackgroundColor e al metodo Console.ResetColor. Per vedere gli effetti dei colori descritti è necessario eseguire l'esempio su una console.

Due costanti, Black e White, vengono utilizzate direttamente. In un momento successivo verranno invece utilizzate tutte le costanti, Blue, DarkRed e così via, indirettamente e all'interno di un ciclo. I nomi delle costanti vengono dapprima ottenuti utilizzando il metodo GetNames, ereditato dalla classe Enum. Il metodo Enum.Parse viene quindi utilizzato per creare da ogni nome la costante enumerata corrispondente.

// 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();
    }
// ---------------------------------------------------------------------------------------
    }
}
/*
This example produces the following results:

All the foreground colors on a constant black background.
  (Black on black is not readable.)

 0: This is foreground color Black.
 1: This is foreground color DarkBlue.
