字节数组与字符串形式的数字（序列号）之间的相互转换

 1 //将字节转换成字符串
 2 public static string Card_Bytes2String(byte[] bCard)
 3 {
 4     if (bCard.Length != 8)
 5     {
 6          throw new ApplicationException("不是有效的数据！");

11      for (int i = 0; i < bCard.Length; i++)
12      {
13           scard += string.Format("{0:X2}", bCard[i]);
14      }
