Process.PeakPagedMemorySize64-Eigenschaft

 

Veröffentlicht: Oktober 2016

Ruft den vom zugeordneten Prozess verwendeten maximalen Arbeitsspeicher in der Auslagerungsdatei des virtuellen Arbeitsspeichers in Bytes ab.

Namespace:   System.Diagnostics
Assembly:  System (in System.dll)

[ComVisibleAttribute(false)]
public long PeakPagedMemorySize64 { get; }

Eigenschaftswert

Type: System.Int64

Die maximale Größe des Arbeitsspeichers in Bytes, der seit dem Starten für den zugeordneten Prozess in der Auslagerungsdatei des virtuellen Arbeitsspeichers belegt wird.

Exception Condition
PlatformNotSupportedException

Die Plattform ist Windows 98 oder Windows Millennium Edition (Windows Me), die diese Eigenschaft nicht unterstützt.

The value returned by this property value represents the maximum size of memory in the virtual memory paging file used by the process since it started, in bytes. The operating system uses the virtual memory paging file in conjunction with physical memory to manage the virtual address space for each process. When pageable memory is not in use, it can be transferred to the virtual memory paging file on disk.

This property can be used to monitor memory usage on computers with 32-bit processors or 64-bit processors. The property value is equivalent to the Page File Bytes Peak performance counter for the process.

Win98WinMe

This property is not supported on Windows 98 or Windows Millennium Edition (Windows Me).

The following code example starts an instance of the Notepad application. The example then retrieves and displays various properties of the associated process. The example detects when the process exits, and displays its exit code and peak memory statistics.

using System.Diagnostics;
