Process.PrivateMemorySize64 Process.PrivateMemorySize64 Process.PrivateMemorySize64 Process.PrivateMemorySize64 Property

Definition

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

public:
 property long PrivateMemorySize64 { long get(); };
[System.Runtime.InteropServices.ComVisible(false)]
public long PrivateMemorySize64 { get; }
member this.PrivateMemorySize64 : int64
Public ReadOnly Property PrivateMemorySize64 As Long
Property Value

The amount of memory, in bytes, allocated for the associated process that cannot be shared with other processes.

Exceptions

The platform is Windows 98 or Windows Millennium Edition (Windows Me), which does not support this property.

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::Diagnostics;

   // memory usage of the process.

   try

Remarks

The value returned by this property represents the current size of memory used by the process, in bytes, that cannot be shared with other processes.

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 Private Bytes performance counter for the process.
