string類型轉成byte[]：

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

?

byte[]轉成string：

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

?

string類型轉成ASCII byte[]：

（"01" 轉成 byte[] = new byte[]{ 0x30,0x31}）

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

?

ASCIIbyte[]轉成string：

（byte[] = new byte[]{ 0x30, 0x31} 轉成"01"）

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

?

byte[]轉16進制格式string：

new byte[]{ 0x30, 0x31}轉成"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進制格式string 轉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<hexString.Length;?i++)

{??????????????

??c?=?hexString[i];if?(IsHexDigit(c))????????????????????

newString?+=?c;

else????????????????????

discarded++;????????????

}//?if?odd?number?of?characters,?discard?last?characterif?(newString.Length?%?2?!=?0){????????????????discarded++;????????????????

newString?=?newString.Substring(0,?newString.Length-1);????????????}

int?byteLength?=?newString.Length?/?2;byte[]?bytes?=?newbyte[byteLength];string?hex;int?j?=?0;for?(int?i=0;?i<bytes.Length;?i++){???????????????

?hex?=?new?String(new?Char[]?{newString[j],?newString[j+1]});???????????????

?bytes[i]?=?HexToByte(hex);????????????????j?=?j+2;???????????

?}

return?bytes;???????

?}
