BCD编码就是 例如 “ab”编码成0XAB

以前是标准C，我没做过

VC倒是有，http://www.shengfang.org简单的就是 sscan “02x”

C#真是难找，http://www.shengfang.org总觉得不应该要编程

原来是这样http://www.shengfang.org

str2bcd：

byte bb= byte.Parse( "ab", System.Globalization.NumberStyles.AllowHexSpecifier);

 //***********************************************************************                                      
       // 将 HexString 转换为 byte[] 数组                                      
       //***********************************************************************
       static http://www.shengfang.org public byte[] HexStringToByte(string hexString)                  
       ...{                                                                     
          byte[] byteResult = new byte[hexString.Length/2];                    
                                                                           
          for(int i = 0; i < hexString.Length/2; i++)                          
             byteResult[i] = Convert.ToByte(hexString.Substring(i*2,2),16);    
                                                                           
          return byteResult;                                                   
       }                                                                       

bcd2str：http://www.shengfang.org

byte []gh=new byte[1];
   gh[0]=0x3;
   string sy=gh[0].ToString("X2");
   System.Diagnostics.Trace.WriteLine( sy);
