将C ++结构转换为C＃

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。 Marshal类具有从结构获取指针（IntPtr）并复制到字节数组的方法。

Answer 2

 [StructLayout(LayoutKind.Sequential)] struct CUSTOM_DATA { int id; ushort port; uint ip; }; CUSTOM_DATA cData ; // use me
