Process.WaitForExit Method ()
Assembly: System (in system.dll)
The wait setting could not be accessed.
There is no process associated with this Process object.
You are attempting to call WaitForExit for a process that is running on a remote computer. This method is available only for processes that are running on the local computer.
The WaitForExit overload is used to make the current thread wait until the associated process terminates. This method instructs the Process component to wait an infinite amount of time for the process to exit. This can cause an application to stop responding. For example, if you call CloseMainWindow for a process that has a user interface, the request to the operating system to terminate the associated process might not be handled if the process is written to never enter its message loop.
This overload ensures that all processing has been completed, including the handling of asynchronous events for redirected standard output. You should use this overload after a call to the WaitForExit(Int32) overload when standard output has been redirected to asynchronous event handlers.
When an associated process exits (that is, when it is shut down by the operation system through a normal or abnormal termination), the system stores administrative information about the process and returns to the component that had called WaitForExit. The Process component can then access the information, which includes the ExitTime, by using the Handle to the exited process.
Because the associated process has exited, the Handle property of the component no longer points to an existing process resource. Instead, the handle can be used only to access the operating system's information about the process resource. The system is aware of handles to exited processes that have not been released by Process components, so it keeps the ExitTime and Handle information in memory until the Process component specifically frees the resources. For this reason, any time you call Start for a Process instance, call Close when the associated process has terminated and you no longer need any administrative information about it. Close frees the memory allocated to the exited process.
