Html Encode method encodes a particular string to be displayed in a browser. It is important to encode strings prior it’s rendering in the page, mainly to avoid cross-site script injection (XSS) and HTML injection attacks. However, developers so often forget to call the encode function.
Html Decode method decodes a particular string which is encoded.
Encoding and decoding is needed in somewhere like
· Pass the values from one page to another.
· Access the URL or pass the URL.
· Fetch the data or insert data in Database.
