プロパティ値
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 ConsoleColor。 既定値は灰色です。
- 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。
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。
I/O エラーが発生しました。
例
次の例では、コンソールの背景色が黒かどうかを確認し、その場合は背景色を赤に、前景色を黒に変更します。
using System;
public class Example
{
public static void Main()
{
if (Console.BackgroundColor == ConsoleColor.Black) {
Console.BackgroundColor = ConsoleColor.Red;
Console.ForegroundColor = ConsoleColor.Black;
Console.Clear();
}
}
}
open System
if Console.BackgroundColor = ConsoleColor.Black then
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、 列挙の値をConsoleColor配列に保存し、 プロパティと ForegroundColor プロパティの現在の値をBackgroundColor変数に格納します。 次に、現在の背景に一致する色を除き、列挙体の ConsoleColor 各色に前景色を変更し、現在の前景に一致する色を除き、列挙型の ConsoleColor 各色に背景色を変更します。 (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 ResetColor 呼び出して元のコンソールの色を復元します。
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...");
}

注釈
コンソールが存在しない Windows ベースのアプリケーションの get 操作は を返します Gray。
Unix システムには、現在のコンソールの色をフェッチするための一般的なメカニズムは用意されていません。 そのため、 ForegroundColor は明示的な方法で (セッターを使用して) 設定されるまで を返 (ConsoleColor)-1
します。
