Process.PagedSystemMemorySize64 Property

Definition

Namespace:

System.Diagnostics

Assemblies:

netstandard.dll, System.Diagnostics.Process.dll

Source:

Process.cs

Gets the amount of pageable system memory, in bytes, allocated for the associated process.

C#

public long PagedSystemMemorySize64 { get; }

Property Value

Int64

The amount of system memory, in bytes, allocated for the associated process that can be written to the virtual memory paging file.

Examples

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.

C#

using System;
using System.Diagnostics;

namespace ProcessSample
{
    class ProcessMonitorSample
    {
        public static void Main()
        {
            // Define variables to track the peak
            // memory usage of the process.
            long peakPagedMem   = 0,
                 peakWorkingSet = 0,
                 peakVirtualMem = 0;

            // Start the process.
            using (Process myProcess = Process.Start("NotePad.exe"))
            {
                // Display the process statistics until
                // the user closes the program.
                do
                {
                    if (!myProcess.HasExited)
                    {
                        // Refresh the current process property values.
                        myProcess.Refresh();

                        Console.WriteLine();

                        // Display current process statistics.

                        Console.WriteLine($"{myProcess} -");
                        Console.WriteLine("-------------------------------------");

                        Console.WriteLine($"  Physical memory usage     : {myProcess.WorkingSet64}");
                        Console.WriteLine($"  Base priority             : {myProcess.BasePriority}");
                        Console.WriteLine($"  Priority class            : {myProcess.PriorityClass}");
                        Console.WriteLine($"  User processor time       : {myProcess.UserProcessorTime}");
                        Console.WriteLine($"  Privileged processor time : {myProcess.PrivilegedProcessorTime}");
                        Console.WriteLine($"  Total processor time      : {myProcess.TotalProcessorTime}");
                        Console.WriteLine($"  Paged system memory size  : {myProcess.PagedSystemMemorySize64}");
                        Console.WriteLine($"  Paged memory size         : {myProcess.PagedMemorySize64}");

                        // Update the values for the overall peak memory statistics.
                        peakPagedMem   = myProcess.PeakPagedMemorySize64;
                        peakVirtualMem = myProcess.PeakVirtualMemorySize64;
                        peakWorkingSet = myProcess.PeakWorkingSet64;

                        if (myProcess.Responding)
                        {
                            Console.WriteLine("Status = Running");
                        }
                        else
                        {
                            Console.WriteLine("Status = Not Responding");
                        }
                    }
                }
                while (!myProcess.WaitForExit(1000));

                Console.WriteLine();
                Console.WriteLine($"  Process exit code          : {myProcess.ExitCode}");

                // Display peak memory statistics for the process.
                Console.WriteLine($"  Peak physical memory usage : {peakWorkingSet}");
                Console.WriteLine($"  Peak paged memory usage    : {peakPagedMem}");
                Console.WriteLine($"  Peak virtual memory usage  : {peakVirtualMem}");
            }
        }
    }
}

Remarks

The value returned by this property value represents the current size of pageable 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. When pageable memory is not in use, it can be transferred to the virtual memory paging file on disk. To obtain the size of the application memory used by the process, use the PagedMemorySize64 property.

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 Paged Bytes performance counter for the process.
