C# byte[]与char[]、string与char[]、byte[] 与 string 互转

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

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[]

string ss="abcdefg";&nbsp

char[] cc=s.ToCharArray();&nbsp

string ss="abcdefg";

char[] cc=s.ToCharArray();

4.Char[] 转换成string

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

byte[] bb=Encoding.UTF8.GetBytes(ss);
string s=Encoding.UTF8.GetString(bb);
byte[] bb=Encoding.UTF8.GetBytes(ss);
string s=Encoding.UTF8.GetString(bb);
