如何从串行端口n读取二进制值，在文本框中显示其十六进制值. [英] How to read binary value from serial port n display its hex value in text box..

问题描述

例如"11101111"，这是我要在转换后如何从串行端口n读取数据的方式，如何显示其十六进制值..

e.g "11101111" this is the data which i want to read it from serial port n after its conversion how to display its hex value ..

推荐答案

取决于关于它如何到达sreail prot:如果它以单个字节到达，则只需从端口读取它，并设置TextBox.Text属性:

Depends on how it arrives at the sreail prot: if it arrives as a single byte, then just read that from the port, and set the TextBox.Text property:

myTextBox.Text = myRecievedByte.ToString("X02");

如果它以字符串"0"和"1"到达，则读取整个字符串并首先进行转换:

If it arrives as a string of ''0'' and ''1'' characters then read the entire string and convert it first:

byte myRecievedByte = Convert.ToByte(myRecievedString, 2);

byte value = serialPort.ReadByte();
string hexString = value.ToString("x2");
