C # Socket send receive byte array and 626 binary conversion function

In the recent use of remote network modules,

The socket to be used to send data, the remote module instruction is 16 binary.

The official demo is a bit cumbersome. Not easy for beginners to use.

The following conversion functions are much easier for beginners to use.

//16 binary string The byte array is formatted as String sendMessage = "The FF-XX";        Private Static byte[] Hexstrtobyte (stringhexstring) {hexstring= Hexstring.replace (" ",""); if((hexstring.length%2) !=0) hexstring+=" "; byte[] Returnbytes =New byte[Hexstring.length/2];  for(inti =0; i < returnbytes.length; i++) Returnbytes[i]= Convert.tobyte (hexstring.substring (i *2,2). Trim (), -); returnreturnbytes; }        //byte array to 16 binary string         Public Static stringBYTETOHEXSTR (byte[] bytes) {            stringReturnstr =""; if(Bytes! =NULL)            {                 for(inti =0; I < bytes. Length; i++) {Returnstr+ = Bytes[i]. ToString ("X2"); }            }            returnReturnstr; }        //byte array to 16 binary simpler, using the Bitconverter.tostring method//string str0x = bitconverter.tostring (result, 0, result. Length). Replace ("-", "" ");
