1. byte array -> char array

    Byte[] b=new byte[5]{0x01,0x02,0x03,0x04,0x05}; 

Char[] c=Encoding.ASCII.GetChars(b); 

 

2. char array -> byte array

    view plaincopy to clipboardprint?
Char[] c=new char[5]{a,b,c,d,e};   
  
Byte[] b=Encoding.Default.GetBytes(c);   
Char[] c=new char[5]{a,b,c,d,e};

Byte[] b=Encoding.Default.GetBytes(c);

 

3.string 转换成 Char[]

   view plaincopy to clipboardprint?
string ss="abcdefg";   
  
char[] cc=s.ToCharArray();  
string ss="abcdefg";

char[] cc=s.ToCharArray();

 
4.Char[] 转换成string

view plaincopy to clipboardprint?
using System.Text;   
  
StringBuilder sb=new StringBuilder();   
foreach(char c in cc)   
{   
  sb.Append(c);   
}   
string s=sb.ToString();  
 using System.Text;

 StringBuilder sb=new StringBuilder();
 foreach(char c in cc)
 {
   sb.Append(c);
 }
 string s=sb.ToString();
 

5.byte[] 与 string

view plaincopy to clipboardprint?
byte[] bb=Encoding.UTF8.GetBytes(ss);   
  
string s=Encoding.UTF8.GetString(bb);  
 byte[] bb=Encoding.UTF8.GetBytes(ss);

 string s=Encoding.UTF8.GetString(bb);
