Re-Encode a String (Hex, Base64, URL, etc)

Demonstrates how to convert from one encoding to another. For example: base64 to hex, URL to base64, base64 to quoted-printable, etc.

Note: The ReEncode method is unreleased at the time of this writing (08-April-2008) The next major Chilkat Crypt2 release after this date will include the ReEncode method.

//  Now convert from quoted-printable to URL:
fromEncoding = "quoted-printable";
toEncoding = "url";
string urlEnc;
urlEnc = crypt.ReEncode(qp,fromEncoding,toEncoding);
textBox1.Text += urlEnc + "\r\n";

//  Now convert from URL back to hex:
fromEncoding = "url";

textBox1.Text += hexStr + "\r\n";

//  The output of this program is:

//  ABCD=E0=E1=E2=E3
//  ABCD%E0%E1%E2%E3
