从byte []数组填充C#结构的最佳方法是什么,其中数据来自C/C++结构？C结构看起来像这样(我的C很生锈):

typedef OldStuff {
    CHAR Name[8];
    UInt32 User;
    CHAR Location[8];
    UInt32 TimeStamp;
    UInt32 Sequence;
    CHAR Tracking[16];
    CHAR Filler[12];
}

并填写这样的东西:

[StructLayout(LayoutKind.Explicit, Size = 56, Pack = 1)]
public struct NewStuff
{
    [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 8)]
    [FieldOffset(0)]
    public string Name;

    [MarshalAs(UnmanagedType.U4)]
    [FieldOffset(8)]
    public uint User;

    [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 8)]
    [FieldOffset(12)]
    public string Location;

    [MarshalAs(UnmanagedType.U4)]
    [FieldOffset(20)]
    public uint TimeStamp;

    [MarshalAs(UnmanagedType.U4)]
    [FieldOffset(24)]
    public uint Sequence;

    [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 16)]
    [FieldOffset(28)]
    public string Tracking;
}

什么是复制OldStuff到的最佳方式NewStuff,如果OldStuff作为byte []数组传递？ …

我有一个系统,远程代理发送序列化结构(来自嵌入式C系统)供我通过IP/UDP读取和存储.在某些情况下,我需要发回相同的结构类型.我以为我使用Marshal.PtrToStructure(接收)和Marshal.StructureToPtr(发送)进行了很好的设置.但是,一个小问题是网络大端整数需要转换为我的x86小端格式才能在本地使用.当我再次发送它们时,大端是可行的方式.

以下是有问题的功能:

    private static T BytesToStruct<T>(ref byte[] rawData) where T: struct
    {
        T result = default(T);
        GCHandle handle = GCHandle.Alloc(rawData, GCHandleType.Pinned);
        try
        {
            IntPtr rawDataPtr = handle.AddrOfPinnedObject();
            result = (T)Marshal.PtrToStructure(rawDataPtr, typeof(T));
        }
        finally
        {
            handle.Free();
        }
        return result;
    }

    private static byte[] StructToBytes<T>(T data) where T: struct
    {
        byte[] rawData = new byte[Marshal.SizeOf(data)];
        GCHandle handle = GCHandle.Alloc(rawData, GCHandleType.Pinned);
        try
        {
            IntPtr rawDataPtr = handle.AddrOfPinnedObject();
            Marshal.StructureToPtr(data, rawDataPtr, false);
        }
        finally
        {
            handle.Free();
        }
        return rawData;
    }

还有一个可以像这样使用的快速示例结构:

byte[] data = this.sock.Receive(ref …
