Process.TotalProcessorTime Property

Gets the total processor time for this process.

[Visual Basic]
Public ReadOnly Property TotalProcessorTime As TimeSpan
[C#]
public TimeSpan TotalProcessorTime {get;}
[C++]
public: __property TimeSpan get_TotalProcessorTime();
[JScript]
public function get TotalProcessorTime() : TimeSpan;

Property Value

A TimeSpan that indicates the amount of time that the associated process has spent utilizing the CPU. This value is the sum of the UserProcessorTime and the PrivilegedProcessorTime.

Exceptions

Exception Type Condition
PlatformNotSupportedException You are accessing this member using Windows 98.

Example

[Visual Basic, C#, C++] 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.
