Public Shared Property BackgroundColor As ConsoleColor

Valeur de propriété

Valeur qui spécifie la couleur d'arrière-plan de la console, c'est-à-dire la couleur affichée derrière chaque caractère.A value that specifies the background color of the console; that is, the color that appears behind each character. La valeur par défaut est noir.The default is black.

Exceptions

La couleur spécifiée dans une opération set n’est pas un membre valide de ConsoleColor.The color specified in a set operation is not a valid member of ConsoleColor.

L’utilisateur n’est pas autorisé à effectuer cette action.The user does not have permission to perform this action.

Une erreur d'E/S s'est produite.An I/O error occurred.

Exemples

L’exemple suivant enregistre les valeurs de l' ConsoleColor énumération dans un tableau et stocke les valeurs actuelles BackgroundColor des ForegroundColor propriétés et dans des 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. Il remplace ensuite la couleur de premier plan par chaque couleur ConsoleColor de l’énumération, à l’exception de la couleur qui correspond à l’arrière-plan actuel, et remplace ConsoleColor la couleur d’arrière-plan par chaque couleur de l’énumération, à l’exception de la couleur qui correspond à premier plan actuel.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 la couleur de premier plan est identique à la couleur d’arrière-plan, le texte n’est pas visible.) Enfin, il appelle la ResetColor méthode pour restaurer les couleurs d’origine de la console.(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.

{
   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;

      }
      
      // Restore the original console colors.
      Console.ResetColor();
      Console.WriteLine("\nOriginal colors restored...");
   }

Remarques

Une modification apportée à la BackgroundColor propriété affecte uniquement la sortie écrite dans des cellules de caractères individuels après la modification de la couleur d’arrière-plan.A change to the BackgroundColor property affects only output that is written to individual character cells after the background color is changed. Pour modifier la couleur d’arrière-plan de la fenêtre de console dans son BackgroundColor ensemble, définissez la Clear propriété et appelez la méthode.To change the background color of the console window as a whole, set the BackgroundColor property and call the Clear method. L'exemple suivant illustre cette situation.The following example provides an illustration.

using System;

public class Example
{
   public static void Main()
   {
      WriteCharacterStrings(1, 26, true);
      Console.MoveBufferArea(0, Console.CursorTop - 10, 30, 1, 
                             Console.CursorLeft, Console.CursorTop + 1);
      Console.CursorTop = Console.CursorTop + 3;
      Console.WriteLine("Press any key..."); 
      Console.ReadKey();

      Console.Clear();
      WriteCharacterStrings(1, 26, false);
   }

   private static void WriteCharacterStrings(int start, int end,
