一、字节数组转换为字符串

[html] view
plain copy

using System;  

   

namespace BasicApp  

{  

    class Program  

    {  

        public static void Main(string[] args)  

        {  

            // 字节数组  

            byte[] bData = {65,66,67,68};  

            // 字符串  

            string str  = BytesToString(bData);  

            // 输出  

            Console.WriteLine("转换后的字符串为： {0}",str);   

               

            string str2  = BytesToString(bData,"GBK");  

            // 输出  

            Console.WriteLine("转换后的字符串为： {0}",str2);   

            Console.ReadKey(true);  

        }  

           

        // 字节数组转换为字符串  

        public static String BytesToString(byte[] bData)  

        {  

           return System.Text.Encoding.GetEncoding(0).GetString(bData);  

        }  

           

        // 字节数组转换为字符串  

        public static String BytesToString(byte[] bData,string encode)  

        {  

           return System.Text.Encoding.GetEncoding(encode).GetString(bData);  

        }  

           

    }  

}  

字节数组转换为字符串的两种方法：System.Text.Encoding.GetEncoding(0).GetString(bytes)和System.Text.Encoding.GetEncoding("GBK").GetString(bytes)

二、字节数组转换为ASCII字符串

[csharp] view
plain copy

using System;  

using System.Text;  

   

namespace BasicApp  

{  

    class Program  

    {  

        public static void Main(string[] args)  

        {  

            // 字节数组  

            byte[] ba = new byte[] { 119,104,97,116,50,49,46,99,111,109 };  

            // 转换为ASCII的字符  

            string s = Encoding.ASCII.GetString(ba);  

            // 打印转换后的内容  

               Console.WriteLine(s);  

                  

            Console.ReadKey(true);  

        }  

            

    }  

}  

C#字节数组转换为ASCII字符的方法：Encoding.ASCII.GetString(bytes);

三、字节数组与Unicode/BigEndianUnicode字符串相互转换

[java] view
plain copy

using System;  

using System.Text;  

   

namespace BasicApp  

{  

    class Program  

    {  

        public static void Main(string[] args)  

        {  

            string s = "IT小奋斗";  

            // 将字符串转换为Unicode数组  

            byte[] bytes = Encoding.BigEndianUnicode.GetBytes(s);  

            foreach (byte b in bytes){  

                Console.Write(b + ",");  

            }  

            Console.WriteLine();  

               

            // 字节数组  

            byte[] bytes1 = new byte[] { 73,0,84,0,15,92,75,89,151,101 };  

            // 转换为 Unicode  

            string str = Encoding.Unicode.GetString(bytes1);  

            Console.WriteLine(str);  

                  

            // 字节数组  

            byte[] bytes2 = new byte[] { 0,73,0,84,92,15,89,75,101,151 };  

            // 转换为 BigEndianUnicode  

            string str2 = Encoding.BigEndianUnicode.GetString(bytes2);  

            Console.WriteLine(str2);  

               

            Console.ReadKey(true);  

        }  

            

    }  

}  

Unicode编码和BigEndianUnicode编码都使是用2个字节对一个字符进行编码，不同点就是过储存字符的顺序正好相反，即前后颠倒。

四、按照编码（ASCII、UTF7、UTF8、Unicode、BigEndianUnicode和UTF32）将字符串转换为字节数组

[csharp] view
plain copy

using System;  

using System.IO;  

using System.Text;  

   

namespace BasicApp  

{  

    class Program  

    {  

        public static void Main(string[] args)  

        {  

            string file = "c://what21.txt";  

            using (StreamWriter output = new StreamWriter(file))   

            {  

                // 写出文件的字符串  

                string srcString = "IT小奋斗";  

       

                // 安装不同的编码转换为数组  

                byte[] asciiString = Encoding.ASCII.GetBytes(srcString);  

                byte[] utf7String = Encoding.UTF7.GetBytes(srcString);  

                byte[] utf8String = Encoding.UTF8.GetBytes(srcString);  

                byte[] unicodeString = Encoding.Unicode.GetBytes(srcString);  

                byte[] beUnicodeString = Encoding.BigEndianUnicode.GetBytes(srcString);  

                byte[] utf32String = Encoding.UTF32.GetBytes(srcString);  

                   

                // 格式化输出编码数组   

                output.WriteLine("ASCII  Bytes: {0}", BitConverter.ToString(asciiString));  

                output.WriteLine("UTF-7  Bytes: {0}", BitConverter.ToString(utf7String));  

                output.WriteLine("UTF-8  Bytes: {0}", BitConverter.ToString(utf8String));  

                output.WriteLine("Unicode  Bytes: {0}", BitConverter.ToString(unicodeString));  

                output.WriteLine("BigEndianUnicode  Bytes: {0}", BitConverter.ToString(beUnicodeString));  

                output.WriteLine("UTF32  Bytes: {0}", BitConverter.ToString(utf32String));  

                   

                // Console输出  

                Console.WriteLine(BitConverter.ToString(utf8String));  

                Console.WriteLine(BitConverter.ToString(utf7String));  

                Console.WriteLine(BitConverter.ToString(asciiString));  

                Console.WriteLine(BitConverter.ToString(unicodeString));  

                Console.WriteLine(BitConverter.ToString(beUnicodeString));  

                Console.WriteLine(BitConverter.ToString(utf32String));  

            }  

            Console.ReadKey(true);  

        }  

            

    }  

}  

将一个字符串，按照编码ASCII、UTF7、UTF8、Unicode、BigEndianUnicode和UTF32分别转换成编码后的数组，经过BitConverter类格式化后，保存到文件并Console打印。
