C# 编写的简单易懂的串口通讯代码带CRC校验 带详细的注释

2、"///是否每字符用逗号分隔///publicstaticstringToHex(strings,stringcharset,boolfenge){if((s.Length%2)!=0){s+="";//空格//thrownewArgumentException("sisnotvalidchinesestring!");}System.Text.Encodingchs=System.Text.Encoding.GetEncoding(charset);byte[]bytes=c

3、hs.GetBytes(s);stringstr="";for(inti=0;i///从16进制转换成汉字/////////编码,如"utf-8","gb2312"

4、am>///publicstaticstringUnHex(stringhex,stringcharset){if(hex==null)thrownewArgumentNullException("hex");hex=hex.Replace(",","");hex=hex.Replace("","");hex=hex.Replace("\","");hex=hex.Replace("","");if(hex.Length%2!=0){hex+="20";//空格//thrownewArgumentException("hexisnotava

5、lidnumber!","hex");}//需要将hex转换成byte数组。byte[]bytes=newbyte[hex.Length/2];for(inti=0;i

6、exnumber!","hex");}}System.Text.Encodingchs=System.Text.Encoding.GetEncoding(charset);returnchs.GetString(bytes);}}//________________________________________________________________________classClass_SerialPort{///
