Udp sbyte send

Question

Hello, I am communicating with a device in UDP, I send byte type values ​​from 0 to 255 and some Sbyte type values ​​from -128 to +127. my question arises in relation to the Sbyte type value, How I can send them via UDP while the UDPclient only takes a byte array ? Example when I put -5 in argument 1 it gives the 4 bits on the photo ![69763-capture.jpg][1] [1]: /api/attachments/69763-capture.jpg?platform=QnA

Just cast your sbyte value to byte and you assign the values to byte array.

byte[] buffer = new byte[1];
sbyte a = -5;
buffer[0] = (byte)a;
Console.Write(Convert.ToString(buffer[0], 2));   //shows 11111011

Btw, the value you see in the image you upload is correct. You are slicing 4 bytes from the array to write it as Int32, so it becomes 0xFFFFFFFB, where those "FF" are 255 and "FB" is 251.
