Wyjątki

NotSupportedException

Próbujesz uzyskać dostęp do ExitTime właściwości dla procesu uruchomionego na komputerze zdalnym. Ta właściwość jest dostępna tylko dla procesów uruchomionych na komputerze lokalnym.

Przykłady

Poniższy przykład kodu tworzy proces, który drukuje plik. Proces zgłasza zdarzenie po jego zakończeniu Exited , a program obsługi zdarzeń wyświetla ExitTime właściwość i inne informacje o procesie.

using System;
using System.Diagnostics;
using System.Threading.Tasks;

class PrintProcessClass
{
    private Process myProcess;
    private TaskCompletionSource<bool> eventHandled;

    // Print a file with any known extension.
    public async Task PrintDoc(string fileName)
    {
        eventHandled = new TaskCompletionSource<bool>();

        using (myProcess = new Process())
        {
            try
            {
                // Start a process to print a file and raise an event when done.

Uwagi

Jeśli proces nie został zakończony, próba pobrania ExitTime właściwości zgłasza wyjątek. Użyj HasExited polecenia przed pobraniem właściwości , ExitTime aby określić, czy skojarzony proces został zakończony.
