ConsoleColor 列挙体

メモ : この列挙体は、.NET Framework version 2.0 で新しく追加されたものです。

コンソールの前景色と背景色を定義する定数を指定します。

使用例使用例

Console.ForegroundColor プロパティ、Console.BackgroundColor プロパティ、および Console.ResetColor メソッドと組み合わせて、System.ConsoleColor 列挙体を使用するコード例を次に示します。説明する色の効果を確認するには、コンソールでこの例を実行する必要があります。

Black と White の 2 つの定数は直接使用され、他のすべての定数 (Blue、DarkRed など) は、ループ内で間接的に使用されます。まず、GetNames メソッドを使用して、定数の名前を取得します。このメソッドは、Enum クラスから継承されます。次に、Enum.Parse メソッドでそれぞれの名前を使用して、対応する列挙型定数を作成します。
