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.
#using <system.dll>
using namespace System;
using namespace System::Diagnostics;
int main()
{
// Define variables to track the peak
// memory usage of the process.
_int64 peakPagedMem = 0,peakWorkingSet = 0,peakVirtualMem = 0;
Process^ myProcess = nullptr;
try
{
// Start the 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( "{0} -", myProcess );
Console::WriteLine( "-------------------------------------" );

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.
