Answer 1

In VB and Net 6, it works natively

I tested for example :

 Dim UrlEncodedOutput = System.Web.HttpUtility.UrlEncode(your_string_to_encode)

Hello there!

Welcome to Microsoft Forums!

The System.Web.HttpUtility class provides several useful methods for encoding and decoding strings in a way that is safe for use in URLs and HTML. However, it's not included in the .NET 6 framework by default.

You can use the System.Net.WebUtility class in place of System.Web.HttpUtility, which is included in .NET 6 and provides similar functionality.

Here's an example of how you can use System.Net.WebUtility to encode a string for use in a URL:

Dim originalString As String = "Hello World!"
Dim encodedString As String = System.Net.WebUtility.UrlEncode(originalString)

Console.WriteLine(encodedString) This will output Hello%20World%21

Here's an example of how you can use System.Net.WebUtility to HTML encode a string to protect against XSS attack

Dim originalString As String = "<script>alert('Hello World!')</script>"
Dim encodedString As String = System.Net.WebUtility.HtmlEncode(originalString)

Console.WriteLine(encodedString) This will output <script>alert('Hello World!')</script>

You can also use System.Net.WebUtility class's methods such as UrlDecode and HtmlDecode to Decode the encoded string respectively.

Note that you have to import System.Net namespace first in the top of your code, which you can do by adding the following line to your code:

Imports System.Net

I hope this helps you! Let me know if you have any other questions.
