C # How to determine if the EXE called by the program has ended

Two Methods: Take the system notepad as an Example

Method 1: This method will block the current process until the running external program exits.
System. Diagnostics. Process exep = system. Diagnostics. process. Start (@ "C: windowsnotepad.exe ");
Exep. waitforexit (); // key. It can be executed only after the external program exits.
MessageBox. Show ("notepad.exe finished running ");

Method 2: Add an event monitor for an external process. After exiting, get the notification. This method does not block the current process. You can handle other tasks.
System. Diagnostics. Process exep = Newsystem. Diagnostics. Process ();
Exep. startinfo. filename = @ "C: \ WINDOWS \ notepad.exe ";
Exep. enableraisingevents = true;
Exep. exited + = new eventhandler (exep_exited );
Exep. Start ();

 

// Exep_exited event processing Code. The Code is activated after the external program exits and can be executed.
Void exep_exited (Object sender, eventargs E)
{

MessageBox. Show ("notepad.exe finished running ");
}
