将C ++结构转换为C#

标签: c# c++ struct

我在下面有一个C ++结构:

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#代码将是什么?

[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);
}

此结构的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,您可以直接发送二进制数据。 Marshal class具有从结构获取指针(IntPtr)并复制到字节数组的方法。

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