Help!! How can I get the information of the memory used of a process??

[Lyon]

Here is a part of my code:

internal bool Excute(string input)
{

ProcessStartInf o psi = new ProcessStartInf o();
psi.FileName = this.filePathTo Excute;

psi.RedirectSta ndardOutput = true;
psi.RedirectSta ndardError = true;
psi.RedirectSta ndardInput = true;
psi.UseShellExe cute = false;

Process p = new Process();
p.StartInfo = psi;

p.ErrorDataRece ived += new
DataReceivedEve ntHandler(p_Err orDataReceived) ;
p.OutputDataRec eived += new
DataReceivedEve ntHandler(p_Out putDataReceived );
p.Start();

//peakMemory = p.PeakWorkingSe t64;//It is the right place
to get the information of memory used by the process p here??

p.BeginOutputRe adLine();
p.BeginErrorRea dLine();

p.WaitForExit(2 000);

if (!p.HasExited)
{
p.ErrorDataRece ived -= new
DataReceivedEve ntHandler(p_Err orDataReceived) ;
p.OutputDataRec eived -= new
DataReceivedEve ntHandler(p_Out putDataReceived );

p.Kill();
p.Close();

return false;
}

excuteTime = p.TotalProcesso rTime;
peakMemory =p.PrivateMemor ySize64;//And again. It is the
right place to get the information of memory used by the process p
here??
/* NonpagedSystemM emorySize64=p.N onpagedSystemMe morySize64;
PagedMemorySize 64=p.PagedMemor ySize64;
PagedSystemMemo rySize64=p.Page dSystemMemorySi ze64;
PeakPagedMemory Size64=p.PeakPa gedMemorySize64 ;
PeakVirtualMemo rySize64=p.Peak VirtualMemorySi ze64;
PeakWorkingSet6 4=p.PeakWorking Set64;
PrivateMemorySi ze64=p.PrivateM emorySize64;
VirtualMemorySi ze64=p.VirtualM emorySize64;
WorkingSet64 = p.WorkingSet64;

*/ //Here are so many memory information related properties of the
process, and which one is the physical memory used by the process p??

p.Close();
}
Thank you very much!

A confused boy is lingering to find the information of physical memory
used by the process.
