Class PropertyValue

Namespace

AudioDeviceLib.CoreAudioApi

Assembly

AudioDeviceLib.dll

Represents a property value read from a Core Audio PropertyStore. This class encapsulates the property type and its value, and indicates whether the property is empty or null. The snapshot holds no unmanaged resources and requires no cleanup.

Properties

IsEmpty

Gets whether the variant type is VT_EMPTY or VT_NULL.

public bool IsEmpty { get; }

Property Value

bool

IsSupported

Gets whether VarType is a variant type this library converts to a managed value.

public bool IsSupported { get; }

Property Value

bool

Remarks

false means the property exists but carries a type (a vector, an array, a stream) that is not read, so Value is null for a reason other than emptiness. Check this before treating a null Value as the property's actual value.

Value

Gets the managed value, or null for an empty, null, or unsupported variant type.

public object? Value { get; }

Property Value

object

Remarks

IsEmpty and IsSupported tell the two null cases apart. Blob values are mutable byte arrays.

VarType

Gets the native variant type of the snapshot.

public VarEnum VarType { get; }

Property Value

VarEnum
