由Marshal编写长数组的结构

问题描述

我正在尝试更改此内容：

    [StructLayout(LayoutKind.Sequential,Pack = 1)]
    public class Frame : BinaryStruct
    {
        [MarshalAs(UnmanagedType.ByValArray,SizeConst = 256)]
        public ulong[] array1 = new ulong[256];
        [MarshalAs(UnmanagedType.ByValArray,SizeConst = 256)]
        public ushort[] array2 = new ushort[256];
        [MarshalAs(UnmanagedType.ByValArray,SizeConst = 16)]
        public ushort[] array3 = new ushort[16];
        [MarshalAs(UnmanagedType.I8,SizeConst = 16)]
        public long[] iP = new long[16];

        public Frame()
        {
            array1 = new ulong[256];
            array2 = new ushort[16];
            array3 = new ushort[256];
            iP = new long[16];
        }
    }

通过字节数组：

    public virtual byte[] ToArray()
    {
        int size = Marshal.SizeOf(this);

        IntPtr ptr = Marshal.AllocHGlobal(size);
        Marshal.StructuretoPtr(this,ptr,false);
        byte[] array = new byte[size];
        Marshal.copy(ptr,array,size);
        Marshal.FreeHGlobal(ptr);
        return array;
    }

它可以不使用

    [MarshalAs(UnmanagedType.I8,SizeConst = 16)]
    public long[] iP = new long[16];

long iP =新的IpAddrees（...）。地址

我认为问题是UnmanagedType。I8我正在尝试I4，但是它不起作用。

错误：

Managed Debugging Assistant 'NonComVisibleBaseClass':' A QueryInterface 
method call was made requesting the COM-visible class
interface of the 'Frame' managed class. However,since this class is
derived from COM invisible 'WS.BinaryStruct',the call to
QueryInterface will fail. This prevents COM version control rules from

限制COM不可见的基类。 '
