string类型转成byte[]:

byte[] byteArray = System.Text.Encoding.Default.GetBytes ( str );

byte[]转成string:

string str = System.Text.Encoding.Default.GetString ( byteArray );

string类型转成ASCII byte[]:

(”01″ 转成 byte[] = new byte[]{ 0x30,0x31})

byte[] byteArray = System.Text.Encoding.ASCII.GetBytes ( str );

ASCIIbyte[]转成string:

(byte[] = new byte[]{ 0x30, 0x31} 转成”01″)

string str = System.Text.Encoding.ASCII.GetString ( byteArray );

byte[]转16进制格式string:

new byte[]{ 0x30, 0x31}转成”3031″:

publicstaticstring ToHexString ( byte[] bytes ) // 0xae00cf => “AE00CF ”

{string hexString = string.Empty;

if ( bytes != null )

{

StringBuilder strB = new StringBuilder ();

for ( int i = 0; i < bytes.Length; i++ ) { strB.Append ( bytes[i].ToString ( "X2" ) ); } hexString = strB.ToString (); }return hexString; } 16进制格式string 转byte[]: publicstaticbyte[] GetBytes(string hexString, outint discarded) { discarded = 0; string newString = ""; char c;// remove all none A-F, 0-9, charactersfor (int i=0; i
