HostProtectionException

Ta metoda została wykonana na serwerze, takim jak SQL Server, która nie zezwala na dostęp do interfejsu użytkownika.

Przykłady

W poniższym przykładzie przedstawiono metodę Beep . Przykład akceptuje liczbę z zakresu od 1 do 9 jako argument wiersza polecenia i odtwarza sygnał dźwiękowy o tej liczbie razy.

// This example demonstrates the Console.Beep() method.
using System;

class Sample
{
    public static void Main(String[] args)
    {
    int x = 0;
//
    if ((args.Length == 1) &&
        (Int32.TryParse(args[0], out x)) &&
        ((x >= 1) && (x <= 9)))

Uwagi

Domyślnie dźwięk jest odtwarzany z częstotliwością 800 hertz przez czas trwania 200 milisekund.

Beep opakowuje wywołanie funkcji Windows Beep. Czy Beep tworzy dźwięk na wersjach Windows przed Windows 7 zależy od obecności 8254 programowalnego mikroukładu czasomierza interwału. Począwszy od Windows 7, zależy to od domyślnego urządzenia dźwiękowego.
