Process.PeakWorkingSet64 プロパティ

定義

関連付けられたプロセスによって使用される物理メモリの最大量をバイト数として取得します。Gets the maximum amount of physical memory, in bytes, used by the associated process.

public:
 property long PeakWorkingSet64 { long get(); };
[System.Runtime.InteropServices.ComVisible(false)]
public long PeakWorkingSet64 { get; }
member this.PeakWorkingSet64 : int64
Public ReadOnly Property PeakWorkingSet64 As Long

プロパティ値

プロセスの開始以降、関連付けられたプロセスに割り当てられた物理メモリの最大量 (バイト単位)。The maximum amount of physical memory, in bytes, allocated for the associated process since it was started.

属性

次のコード例では、メモ帳アプリケーションのインスタンスを起動します。The following code example starts an instance of the Notepad application. 次に、この例では、関連付けられているプロセスのさまざまなプロパティを取得して表示します。The example then retrieves and displays various properties of the associated process. この例では、プロセスが終了したことを検出し、終了コードとピークメモリの統計情報を表示します。The example detects when the process exits, and displays its exit code and peak memory statistics.

注釈

このプロパティによって返される値は、プロセスが開始してから使用されるワーキングセットメモリの最大サイズをバイト単位で表します。The value returned by this property represents the maximum size of working set memory used by the process since it started, in bytes. プロセスのワーキングセットは、物理 RAM メモリ内のプロセスに現在表示されているメモリページのセットです。The working set of a process is the set of memory pages currently visible to the process in physical RAM memory. これらのページは常駐し、アプリケーションがページフォールトをトリガーすることなく使用できます。These pages are resident and available for an application to use without triggering a page fault.

ワーキングセットには、共有データとプライベートデータの両方が含まれます。The working set includes both shared and private data. 共有データには、プロセスモジュールやシステムライブラリからの指示を含め、プロセスが実行するすべての命令を含むページが含まれます。The shared data includes the pages that contain all the instructions that the process executes, including instructions from the process modules and the system libraries.

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ーのメモリ使用量を監視するために使用できます。This property can be used to monitor memory usage on computers with 32-bit processors or 64-bit processors. プロパティ値は、プロセスのワーキングセットのピーク時のパフォーマンスカウンターと同じです。The property value is equivalent to the Working Set Peak performance counter for the process.
