How can I merge bytes format

string s = textBox1.Text;
            byte[] bytes = Encoding.ASCII.GetBytes(s);            

            //byte[] bytesToSend = new byte[16] { 0x01, 0x46, 0x42, 0x44, 0x2d, 0x2d, 0x2d, 0x53, 0x2d, 0x2d, 0x2d, 0x2d, 0x2d, 0x2d, 0x2d, 0x17};
            byte[] bytesToSend = new byte[7] { 0x01, 0x46, 0x4d, 0x42, 0x2d, 0x2d, 0x2d };
            byte b3 = (byte)(bytesToSend & bytes);

            clientSocket.Send(b3);

thank you

What I have tried:

I tryid operators & and + but still error CS0019 Operator '&' cannot be applied to operands of type 'byte[]' and 'byte[]'

Solution 1

You can't AND whole arrays: AND is an operator that works on individual elements of the array, as it "+". If that you want to do is combine the two arrays so your get one bigger array with all the elements of one followed by all the elements of the other, then do this:

byte[] a1 = new byte[16] { 0x01, 0x46, 0x42, 0x44, 0x2d, 0x2d, 0x2d, 0x53, 0x2d, 0x2d, 0x2d, 0x2d, 0x2d, 0x2d, 0x2d, 0x17};
byte[] a2 = new byte[7] { 0x01, 0x46, 0x4d, 0x42, 0x2d, 0x2d, 0x2d };
byte[] combined = a1.Concat(a2).ToArray();

Sorry, I try to merge byte[] bytes = Encoding.ASCII.GetBytes(s);

and

byte[] bytesToSend = new byte[7] { 0x01, 0x46, 0x4d, 0x42, 0x2d, 0x2d, 0x2d };

Then you need to specify *exactly* what you expect to get as a result.
If you have two arrays
byte[] a1 = new byte[] { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09};
byte[] a2 = new byte[] { 0x10, 0x20, 0x30, 0x40, 0x50, 0x60, 0x70};
Then exactly what do you expect the "merger" to produce and why? There are a huge number of possibilities!

In textbox1 is text =00990202. I want merge byte row "bytesToSend" with textbox1 text to one row and send this row via clientsocket. Bytetosend + textbox1 and send this full row.

That tells me nothing.
I have no idea where the string "00990202" is supposed to come from or how you need to "merge" the bytes with it.

Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with. So stop trying to type as little as possible, or we will be here all day! :laugh:

My solution

string s = textBox1.Text;
            var bytes = Encoding.ASCII.GetBytes(s);            

            //načtení souboru
            byte[] bytesToSend = new byte[8] { 0x01, 0x46, 0x4d, 0x42, 0x2d, 0x2d, 0x2d, 0x52 };
            byte[] bytesToSend2 = new byte[1] {0x17};           

            var load = bytesToSend.Concat(bytes).ToArray();
            var load2 = load.Concat(bytesToSend2).ToArray();
            clientSocket.Send(load2);        

            //print souboru
            System.Threading.Thread.Sleep(1000);
            byte[] print = new byte[16] { 0x01, 0x46, 0x42, 0x44, 0x2d, 0x2d, 0x2d, 0x53, 0x2d, 0x2d, 0x2d, 0x2d, 0x2d, 0x2d, 0x2d, 0x17 };
            clientSocket.Send(print);

            clientSocket.Close();
