Property Value
Type:
System..::.Int64The amount of memory, in bytes, allocated for the associated process that cannot be shared with other processes.
| Exception | Condition |
|---|
| PlatformNotSupportedException | The platform is Windows 98 or Windows Millennium Edition (Windows Me), which does not support this property. |
The value returned by this property represents the current size of memory used by the process 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.
Windows 98, Windows Millennium Edition Platform Note:
This property is not supported on Windows 98 or Windows Millennium Edition (Windows Me).
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.
