Console.WindowLeft プロパティ

メモ : このプロパティは、.NET Framework version 2.0 で新しく追加されたものです。

コンソールウィンドウ領域の左端の位置を、画面バッファに対する相対位置として取得または設定します。

名前空間: System
アセンブリ: mscorlib (mscorlib.dll 内)
構文

Visual Basic (宣言)

Public Shared Property WindowLeft
 As Integer

Visual Basic (使用法)

Dim value As Integer

value = Console.WindowLeft

Console.WindowLeft = value

public static int WindowLeft
 { get; set; }

C++

public:
static property int WindowLeft {
    int get ();
    void set (int value);
}

/** @property */
public static int get_WindowLeft
 ()

/** @property */
public static void set_WindowLeft
 (int value)

JScript

public static function get
 WindowLeft () : int

public static function set
 WindowLeft (value : int)

プロパティ値
コンソールウィンドウの左端の位置 (列)。

例外

例外の種類	条件
IOException	情報の読み取り中または書き込み中にエラーが発生しました。

使用例

WindowLeft、WindowTop、WindowWidth、WindowHeight、BufferWidth、BufferHeight、CursorVisible の各プロパティ、および SetWindowPosition、SetBufferSize、ReadKey の各メソッドの使用例を次に示します。この例は、画面バッファの幅に基づいて、画面バッファ内にグリッドパターンを描画するものです。特定のコンソールキー (↑、↓、←、または →) が押された場合は、そのキーに応じてコンソールウィンドウを移動します。このグリッドパターンを見ると、画面バッファに対するコンソールウィンドウの相対的な動きを確認できます。
