Process.VirtualMemorySize64 プロパティ
アセンブリ: System (system.dll 内)

関連付けられたプロセスに割り当てられた仮想メモリの量 (バイト単位)。

例外の種類 | 条件 |
---|---|
PlatformNotSupportedException | プラットフォームが Windows 98 または Windows Millennium Edition (Windows Me) です。このプロパティはサポートされません。 |

このプロパティによって返された値は、プロセスが使用する仮想メモリの現在のサイズを表します。オペレーティング システムは、物理メモリに読み込まれたページまたはディスク上の仮想メモリ ページング ファイルに対して各プロセスの仮想アドレス空間を割り当てます。
このプロパティは、32 ビット プロセッサまたは 64 ビット プロセッサを搭載したコンピュータで、メモリ使用量を監視する場合に使用できます。プロパティ値は、プロセスの Virtual Bytes のパフォーマンス カウンタと等価です。
Windows 98, Windows Millennium Edition プラットフォームメモ : このプロパティは、Windows 98 または Windows Millennium Edition (Windows Me) ではサポートされていません。

メモ帳アプリケーションのインスタンスを起動するコード例を次に示します。この例では、インスタンスの起動後、関連付けられているプロセスのさまざまなプロパティが取得および表示されます。この例は、プロセスの終了を検知し、終了コードとピーク メモリ統計情報を表示します。
