Process.PagedMemorySize64 Property

Definition

Namespace:

System.Diagnostics

Assemblies:

netstandard.dll, System.Diagnostics.Process.dll

Source:

Process.cs

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

C#

public long PagedMemorySize64 { get; }

Property Value

Int64

The amount of memory, in bytes, allocated in the virtual memory paging file for the associated process.

Examples

The following code example starts an instance of the Notepad application, and 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 represents the most recently refreshed size of memory in the virtual memory paging file used by the process, in bytes. To get the most up to date size, you need to call Refresh() method first.

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. To obtain the size of memory used by the operating system for the process, use the PagedSystemMemorySize64 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 Page File Bytes performance counter for the process.
