Propiedad Process.NonpagedSystemMemorySize64

 

Publicado: octubre de 2016

Obtiene el tamaño de la memoria no paginada del sistema en bytes que se asignó para el proceso asociado.

Espacio de nombres:   System.Diagnostics
Ensamblado:  System (en System.dll)

[ComVisibleAttribute(false)]
public long NonpagedSystemMemorySize64 { get; }

Valor de propiedad

Type: System.Int64

Tamaño de la memoria del sistema, expresado en bytes, que se asignó para el proceso asociado que no puede escribirse en el archivo de paginación de la memoria virtual.

Exception Condition
PlatformNotSupportedException

La plataforma es Windows 98 o Windows Millennium Edition (Windows Me), que no admite esta propiedad.

The value returned by this property represents the current size of nonpaged system memory used by the process, in bytes. System memory is the physical memory used by the operating system, and is divided into paged and nonpaged pools. Nonpaged memory allocations remain in system memory and are not paged out to the virtual memory paging file.

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 Pool Nonpaged Bytes 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;

            // memory usage of the process.
            long peakPagedMem = 0,
                peakWorkingSet = 0,
                peakVirtualMem = 0;

                myProcess = Process.Start("NotePad.exe");

                // Display the process statistics until
                // the user closes the program.
