The method causes the process to stop waiting for exit if it was waiting, closes the process handle, and clears process-specific properties. does not close the standard output, input, and error readers and writers in case they are being referenced externally.
The following example starts an instance of Notepad. It then retrieves the physical memory usage of the associated process at 2-second intervals for a maximum of 10 seconds. The example detects whether the process exits before 10 seconds have elapsed. The example closes the process if it is still running after 10 seconds.
