名前	説明
Beep()	本体のスピーカーからビープ音の音を再生します。
Beep(Int32, Int32)	本体のスピーカーを通して、指定した周波数と継続時間のビープ音の音を再生します。

Beep()

本体のスピーカーからビープ音の音を再生します。

public:
 static void Beep();

public static void Beep();

static member Beep : unit -> unit

Public Shared Sub Beep ()

例外

HostProtectionException

このメソッドは、ユーザーインターフェイスへのアクセスを許可しないサーバー (SQL Server など) で実行されました。

例

次の例では、 Beep メソッドを示します。この例では、コマンドライン引数として 1 ~ 9 の数値を受け取り、その回数だけビープ音を再生します。

注釈

既定では、ビープ音は 200 ミリ秒の間、800 ヘルツの周波数で再生されます。

Beep は、Windows Beep 関数への呼び出しをラップします。 BeepがWindows 7前にWindowsのバージョンでサウンドを生成するかどうかは、8254 プログラム可能な間隔タイマーチップの有無によって異なります。 Windows 7以降は、既定のサウンドデバイスによって異なります。

適用対象

Beep(Int32, Int32)

本体のスピーカーを通して、指定した周波数と継続時間のビープ音の音を再生します。

public:
 static void Beep(int frequency, int duration);

public static void Beep(int frequency, int duration);

static member Beep : int * int -> unit

Public Shared Sub Beep (frequency As Integer, duration As Integer)

パラメーター

frequency: Int32

37 から 32767 ヘルツまでのビープ音の頻度。

duration: Int32

ビープ音の継続時間をミリ秒単位で測定します。

例外

ArgumentOutOfRangeException

frequency が 37 未満または 32767 ヘルツを超えています。

-または-

duration が 0 以下です。

HostProtectionException

このメソッドは、コンソールへのアクセスを許可しないサーバー (SQL Server など) で実行されました。

PlatformNotSupportedException

現在のオペレーティングシステムは Windows ではありません。

例

この例では、本体のスピーカーから曲の最初のいくつかのノートを再生して、 Beep 方法を示します。
