Try this

[StructLayout(LayoutKind.Explicit)]
struct PROPVARIANT
{
   [FieldOffset(0)] public short     vt;
   [FieldOffset(2)] public short     wReserved1;
   [FieldOffset(4)] public short     wReserved2;
   [FieldOffset(6)] public short     wReserved3;
   [FieldOffset(8)] public sbyte     cVal;
   [FieldOffset(8)] public byte      bVal;
   [FieldOffset(8)] public short     iVal;
   [FieldOffset(8)] public ushort    uiVal;
   [FieldOffset(8)] public int       lVal;
   [FieldOffset(8)] public uint      ulVal;
   [FieldOffset(8)] public long      hVal;
   [FieldOffset(8)] public ulong     uhVal;
   [FieldOffset(8)] public float     fltVal;
   [FieldOffset(8)] public double    dblVal;
   [MarshalAs(UnamangedType.Currency)]
   [FieldOffset(8)] public decimal   cyVal;
   [FieldOffset(8)] public DateTime  cyVal;
   [MarshalAs(UnamangedType.VariantBool)]
   [FieldOffset(8)] public bool      boolVal;
   [MarshalAs(UnamangedType.Error)]
   [FieldOffset(8)] public int       scode;
   [FieldOffset(8)] public FILETIME  filetime;

   [FieldOffset(8)] public IntPtr    everything_else;
}
