一、字节数组转换为字符串

[html]view plaincopy 
   
 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 plaincopy 
   
 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 plaincopy 
   
 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 plaincopy 
   
 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);  
         }  
             
     }  
 }
