使用类字节Marshal.SizeOf错误[]类[]类型的数据

您好，

我使用这个类:

[StructLayout(LayoutKind.Sequential, Pack = 1)]

    class THolidayTz

    {

        public ushort ID;

        [MarshalAs(UnmanagedType.ByValArray, SizeConst = 4, ArraySubType = 0)]

        public byte[][] HDate = new byte[4][]; // Error using Marshal.SizeOf

        public ushort TZID;

    };

public byte[]HDate = new byte[4];
