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

Char[] c=Encoding.ASCII.GetChars(b); 

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);
