How to play system sounds in C#

.NET Framework allows playing system sounds using a simple code:

SystemSounds.[Type].Play(); 
But the SystemSounds class supports only 5 types of sound notifications: Asterisk, Beep, Exclamation, Hand, Question.

There is no easy way to play other standard sounds like LowBatteryAlarm, DeviceConnect, DeviceDisconnect, MailBeep, and others from the Windows Sound Scheme.

We in BgRnD are using following function in our C# projects:

public void PlaySystemSound(string RegistryName)
{
    string fileName = "";

    RegistryKey key = Registry.CurrentUser.OpenSubKey(String.Format(@"AppEvents\Schemes\Apps\.Default\{0}\.Current", RegistryName), false);
    try
    {
        fileName = (string)key.GetValue("", fileName);
    }
    finally
    {
        key.Close();
    }

    if (!File.Exists(fileName)) return;

    SoundPlayer player = new SoundPlayer(fileName);
    try
    {
        player.Play();
    }
    finally
    {
        player.Dispose();
    }
}

The function plays the sound resource specified by the RegistryName parameter. The set of possible names you can find in the System Registry at HKEY_CURRENT_USER\AppEvents\Schemes\Apps\.Default path.

You can freely use (copy and paste) this function into any of your projects.

Great tool to generate WMI queries

If you are planning to work with System.Management Namespace in the .NET framework, especially with ManagementObjectSearcher, ManagementObjectCollection, and ManagementObject classes, to perform different Windows Management Instrumentation (WMI) queries, take a look on WMI Code Creator tool by Microsoft.

Without this free utility, you'll spending lots of time to test your WMI queries via console or other debugging methodology.

Using the WMI Query Builder you can browse WMI namespaces, execute methods and receive WMI events. Also you can automatically generate a working source code to perform WMI queries, either C# or Visual Basic.

Moreover, you can modify and run these management scripts by pressing a single button! Visual Studio is not required for that 🙂
