Process.PrivilegedProcessorTime Property

Gets the privileged processor time for this process.

Namespace:  System.Diagnostics
Assembly:  System (in System.dll)

[MonitoringDescriptionAttribute("ProcessPrivilegedProcessorTime")]
public TimeSpan PrivilegedProcessorTime { get; }

Property Value

Type: System.TimeSpan
A TimeSpan that indicates the amount of time that the process has spent running code inside the operating system core.

ExceptionCondition
PlatformNotSupportedException

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

NotSupportedException

You are attempting to access the PrivilegedProcessorTime property for a process that is running on a remote computer. This property is available only for processes that are running on the local computer.

The following example starts an instance of Notepad. The example then retrieves and displays various properties of the associated process. The example detects when the process exits, and displays the process's exit code.
