Question

C++ code:

struct tPacket {     WORD word1;     WORD word2;     BYTE byte1;     BYTE byte2;     BYTE array123[8]; }  static char data[8192] = {0}; ... some code to fill up the array ... tPacket * packet = (tPacket *)data; 

We can’t do that as easy in C#.

Please note there is an array in the C++ structure.

Alternatively, using this source file could do the job for us, but not if there is an array in the structure.

Answer 1

What you are looking for (if you are using a similar structure definition like @JaredPar posted) is something like this:

tPacket t = new tPacket(); byte[] buffer = new byte[Marshal.SizeOf(typeof(tPacket))]; socket.Receive(buffer, 0, buffer.length, 0);  GCHandle pin = GCHandle.Alloc(buffer, GCHandleType.Pinned); t = (tPacket)Marshal.PtrToStructure(pin.AddrOfPinnedObject(), typeof(tPacket)); pin.free();  //do stuff with your new tPacket t
