Process.waitforexit example c#

Instructs the Process component to wait the specified number of milliseconds for the associated process to exit. The amount of time, in milliseconds, to wait for the associated process to exit.

The maximum is the largest possible value of a bit integer, which represents infinity to the operating system. No process Id has been set, and a Handle from which the Id property can be determined does not exist. There is no process associated with this Process object.

You are attempting to call WaitForExit Int32 for a process that is running on a remote computer. This method is available only for processes that are running on the local computer. WaitForExit Int32 makes the current thread wait until the associated process terminates. It should be called after all other methods are called on the process. To avoid blocking the current thread, use the Exited event. This method instructs the Process component to wait a finite amount of time for the process to exit.

If the associated process does not exit by the end of the interval because the request to terminate is denied, false is returned to the calling procedure. You can specify a negative number Infinite for milliseconds , and Process.

WaitForExit Int32 will behave the same as the WaitForExit overload. If you pass 0 zero to the method, it returns true only if the process has already exited; otherwise, it immediately returns false.

When standard output has been redirected to asynchronous event handlers, it is possible that output processing will not have completed when this method returns. To ensure that asynchronous event handling has been completed, call the WaitForExit overload that takes no parameter after receiving a true from this overload.

To help ensure that the Exited event is handled correctly in Windows Forms applications, set the SynchronizingObject property. When an associated process exits is shut down by the operating system through a normal or abnormal termination , the system stores administrative information about the process and returns to the component that had called WaitForExit Int 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.
