how to convert to c# code pack("s",strlen($str)) and $str that json-type.

Answer 1

So you can use json.net to do the json encoding, then something like the following:

var obj     = new StandardClass { variable1 = 202, variable2 = 123 };
var initial = JsonConvert.SerializeObject(obj);
var header  = "\x0a\xff\x00\x10" + initial.Length.ToString("X") + initial;
...
socket.Write(header);
