Convert C++ struct to C#

Question

I have a C++ struct below:

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

How can i convert it to C#

Answer 1

The C# version of this struct would be:

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

As for sending this via a socket, you can just send the binary data directly. The Marshal class has methods for getting a pointer (IntPtr) from the structure and copying into a byte array.

Answer 2

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