All I need to do is to send a structure via SerialPort Control which needs in return an array of Bytes, and then convert it back on the other side! Can anyone help me here :( I am getting pretty desperate here :(( Thanks

Thanks, But in this way I don’t really use the SerialPort Control that .net 2 gave me. Do u know how to do it with the SerialPort Control?

What I need to do is this: To take a structure (or a class that contains only variables) then convert it somehow to an array of bytes, so i will be able to send it with the Write function of the SerialPort Control. On the other side of the port i need to do backward process Can anyone help me with this one? thanks
