C#中Byte[]和String之间转换的方法

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace ByteToString{class Program{static void Main(string[] args){string str = "鞠哥真帅！";//使用UTF编码。。。Byte[] utf8 = StrToByte(str, Encoding.UTF8);//估计C#当时设计时没有中文简体，这是后来中国搞的？Byte[] gb2312 = StrToByte(str,Encoding.GetEncoding("GB2312"));Console.WriteLine("这是UTF8(鞠哥真帅),长度是:{0}",utf8.Length);foreach (var item in utf8){Console.Write(item);}Console.WriteLine("/n/n这是gb2312(鞠哥真帅),长度是:{0}",gb2312.Length);foreach (var item in gb2312){Console.Write(item);}//用utf8编码的字节数组转换为strstring utf8Str = ByteToStr(utf8,Encoding.UTF8);string gb2312Str = ByteToStr(gb2312,Encoding.GetEncoding("GB2312"));Console.WriteLine("/n/nutf8: {0}",utf8Str);Console.WriteLine("gb2312: {0}",gb2312Str);Console.ReadKey();}//C#通常使用System.Text.Encoding编码//字符串转数组static Byte[] StrToByte(string str, Encoding encoding){return encoding.GetBytes(str);}//数组转换字符串static String ByteToStr(Byte[] bt,Encoding encoding){return encoding.GetString(bt);}}}
