Enum VarType

Namespace

NAudio.CoreAudioApi.Interfaces

Assembly

NAudio.Wasapi.dll

PROPVARIANT type tags from propidl.h (the VT_* constants). Numeric values match the COM ABI, so this enum is interchangeable with the PROPVARIANT.vt field via cast. Defined locally to avoid System.Runtime.InteropServices.VarEnum, which is obsolete (SYSLIB0050) as part of the deprecation of built-in VARIANT marshalling.

[Flags]
public enum VarType : ushort
