将C++结构转换为C#

Question

我有一个C++结构如下:

struct CUSTOM_DATA {
   int id;
   u_short port;
   unsigned long ip;
} custom_data;

如何将其转换为C#struct,序列化并通过tcp socket发送？

谢谢!

UPD

那么C#代码会是什么？

[StructLayout(LayoutKind.Sequential)]
public struct CustomData
{
 public int id;
 public ushort port;
 public uint ip;
}

public void Send()
{
 CustomData d = new CustomData();
 d.id = 12;
 d.port = 1000;
 d.ip = BitConverter.ToUInt32(IPAddress.Any.GetAddressBytes(), 0);
 IntPtr pointer = Marshal.AllocHGlobal(Marshal.SizeOf(d));
 Marshal.StructureToPtr(d, pointer, false);
 byte[] data_to_send = new byte[Marshal.SizeOf(d)];
 Marshal.Copy(pointer, data_to_send, 0, data_to_send.Length);
 client.GetStream().Write(data_to_send, 0, data_to_send.Length);
}

Answer 1

这个结构的C#版本将是:

[StructLayout(LayoutKind.Sequential)]
public struct CustomData
{
    public int id;
    public ushort port;
    public uint ip;
}

至于通过套接字发送,你可以直接发送二进制数据.该Marshal类具有用于获得从结构和复制指针(IntPtr的)到一个字节阵列的方法.
