c#编程指南(十七) 字符串和字节流相互转化

字符串和字节流的转化，主要用的是System.Text.Encoding类，下面的代码示例，实现了UTF8,UTF32,GB2312常用编码的文本转化，代码很简单，

也不用解释，放在这里供大家参考，方便之余，还是赞叹一个.net的给力吧！！

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

namespace TextEncoder
{
    class Program
    {
        private static string _test = "Abc";
        //
        static void Main(string[] args)
        {
            //ASCII,UTF7,UTF8,UTF32,UNICODE
            byte[] bytes1 = Encoding.ASCII.GetBytes(_test);
            byte[] bytes2 = Encoding.UTF8.GetBytes(_test);
            byte[] bytes3 = Encoding.Unicode.GetBytes(_test);
            //
            string s1 = Encoding.ASCII.GetString(bytes1);
            string s2 = Encoding.UTF8.GetString(bytes2);
            string s3 = Encoding.Unicode.GetString(bytes3);
            //
            //GB2312,BIG5
            byte[] bytes4 = Encoding.GetEncoding("GB2312").GetBytes(_test);
            byte[] bytes5 = Encoding.GetEncoding("BIG5").GetBytes(_test);
            //
            string s4 = Encoding.GetEncoding("GB2312").GetString(bytes4);
            string s5 = Encoding.GetEncoding("BIG5").GetString(bytes5);
            //
            Console.WriteLine(s1 + ";" + s2 + ";" + s3 + ";" + s4 + ";" + s5);
        }
    }
}
