コンソールの前景色を取得または設定します。Gets or sets the foreground color of the console.

Public Shared Property ForegroundColor As ConsoleColor

プロパティ値

ConsoleColor

コンソールの前景色、つまり、表示される各文字の色を指定する ConsoleColorA ConsoleColor that specifies the foreground color of the console; that is, the color of each character that is displayed. 既定値は灰色です。The default is gray.

属性

例外

設定操作で指定された色は、ConsoleColor の有効なメンバーではありません。The color specified in a set operation is not a valid member of ConsoleColor.

ユーザーにこの操作を実行するアクセス許可がありません。The user does not have permission to perform this action.

I/O エラーが発生しました。An I/O error occurred.

次の例では、コンソールの背景色が黒であるかどうかを確認し、存在する場合は背景色を赤に、前景色を黒に変更します。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

次の例では、列挙体の値を ConsoleColor 配列に保存し、プロパティとプロパティの現在の値を BackgroundColor 変数に格納し ForegroundColor ます。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. 次に、現在の背景と一致する色を除いて、前景色を列挙の各色に変更 ConsoleColorConsoleColor ます。また、現在の前景に一致する色以外の、列挙体の各色に背景色を変更します。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. (前景色が背景色と同じ場合、テキストは表示されません)。最後に、メソッドを呼び出して、 ResetColor 元のコンソールの色を復元します。(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.
