C#-----位元組數組(byte[])和字元串互相轉換

   Encoding類  表示字元編碼

1.字元串轉換成位元組數組byte[]

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace FileStreamTest
{
    class Program
    {
        static void Main(string[] args)
        {
            string str = "Hello World!";
            //将字元串轉換成位元組組
            byte[] bytes = Encoding.Default.GetBytes(str);
            foreach (byte b in bytes)
            {
                Console.Write(b+" ");
            }
            Console.WriteLine();
            Console.ReadLine();

        }
    }
}      

2.位元組數組換成字元串

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace FileStreamTest
{
    class Program
    {
        static void Main(string[] args)
        {
            byte[] bytes = { 72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100, 33 };
            //将位元組組轉換成字元串
            string newStr = Encoding.Default.GetString(bytes);
            Console.Write(newStr);
            Console.ReadLine();
        }
    }
}
