ExceptionCondition
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 maximum size of virtual memory used by the process since it started. The operating system maps the virtual address space for each process either to pages loaded in physical memory, or to pages stored in the virtual memory paging file on disk.

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 Virtual Bytes Peak 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).
