如何将12位手机号转换为6字节数组BCD码？

将一个12位的手机号（11位手机号前补0,如013482339442),转换12个为8421码，然后组合成6字节数组，暂命名为BCD6，转换方法如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleDemo
{
    public class BCD6
    {
        public string GetMobileNo(byte[] mobileArray)
        {
            StringBuilder sb = new StringBuilder();
            for (int i = 0; i < 6; i++)
            { 
                byte bb=mobileArray[i];
                sb.Append(((byte)(bb >> 4)).ToString());
                sb.Append(((byte)((byte)(bb << 4) >> 4)).ToString());
            }
            return sb.ToString();
        }

        public byte[] ConvertToBCD6(string mobileNo)
        { 
            byte[] mobileArray=new byte[6];
            if (mobileNo.Length != 12) return mobileArray;
            for (int i = 0; i < 6; i++)
            {
                mobileArray[i] = Convert.ToByte(mobileNo.Substring(i*2, 2), 16);
            }
            return mobileArray;
        }
    }
}

 控制台测试代码：

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleDemo
{
    class Program
    {
        static void Main(string[] args)
        {

            byte[] mobileArray = new byte[6] { 0x01, 0x34, 0x82, 0x33, 0x94, 0x42 };
            BCD6 bcd6 = new BCD6();
            Console.WriteLine(bcd6.GetMobileNo(mobileArray));

            byte[] mobile2 = bcd6.ConvertToBCD6("013482339442");
            Console.WriteLine(bcd6.GetMobileNo(mobile2));

            Console.Read();
        }
    }
}
