Assembly: System (in system.dll)
After Refresh is called, the first request for information about each property causes the process component to obtain a new value from the associated process.
When a Process component is associated with a process resource, the property values of the Process are immediately populated according to the status of the associated process. If the information about the associated process subsequently changes, those changes are not reflected in the Process component's cached values. The Process component is a snapshot of the process resource at the time they are associated. To view the current values for the associated process, call the Refresh method.
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.
