Process.UserProcessorTime Property

Definition

Gets the user processor time for this process.

public:
 property TimeSpan UserProcessorTime { TimeSpan get(); };
public TimeSpan UserProcessorTime { get; }
member this.UserProcessorTime : TimeSpan
Public ReadOnly Property UserProcessorTime As TimeSpan

Property Value

A TimeSpan that indicates the amount of time that the associated process has spent running code inside the application portion of the process (not inside the operating system core).

Exceptions

You are attempting to access the UserProcessorTime 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.

Examples

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.
