Beispiele

Im folgenden Codebeispiel wird die Verwendung von TimeoutException in Verbindung mit Membern der System.IO.Ports.SerialPort -Klasse veranschaulicht.

// This example demonstrates the use of the TimeoutException
// exception in conjunction with the SerialPort class.

#using <System.dll>

using namespace System;
using namespace System::IO::Ports;

int main()
{
    String^ input;
    try
    {
        // Set the COM1 serial port to speed = 4800 baud, parity = odd,
        // data bits = 8, stop bits = 1.
        SerialPort^ port = gcnew SerialPort("COM1",
            4800, Parity::Odd, 8, StopBits::One);
        // Timeout after 2 seconds.
        port->ReadTimeout = 2000;
        port->Open();

        // Read until either the default newline termination string
        // is detected or the read operation times out.
        input = port->ReadLine();

        port->Close();

        // Echo the input.
        Console::WriteLine(input);
    }

    // Only catch timeout exceptions.
    catch (TimeoutException^ ex)
    {
        Console::WriteLine(ex);
    }
};
/*
This example produces the following results:

(Data received at the serial port is echoed to the console if the
read operation completes successfully before the specified timeout period
expires. Otherwise, a timeout exception like the following is thrown.)

System.TimeoutException: The operation has timed-out.

Hinweise

Informationen zum Festlegen des Timeoutintervalls vor dem Auslösen einer TimeoutException Ausnahme finden Sie in der Dokumentation des Typs, dessen Methode ein Timeout aufweist. Informationen zur Behandlung des Timeouts finden Sie in der Dokumentation für die Methode, die die Ausnahme ausgelöst hat.

TimeoutException verwendet das HRESULT, COR_E_TIMEOUT, das den Wert 0x80131505 hat.

Eine Liste der anfänglichen Eigenschaftswerte für eine Instanz von TimeoutException, finden Sie unter den TimeoutException Konstruktoren.
