C # String types and byte[] types convert each other

Convert string type to byte[]:

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

Convert string type to byte[]:

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

Byte[] turn into string:

String str = System.Text.Encoding.Default.GetString (ByteArray);

The string type turns to ASCII byte[]:

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

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

Asciibyte[] turn into string:

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

String str = System.Text.Encoding.ASCII.GetString (ByteArray);

Byte[] Go to 16 binary format string:

New byte[]{0x30, 0x31} turns into "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 binary format string to 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

{

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;

}
