HttpUtility.UrlEncode in Windows Phone 7?

Silverlight has the Uri.EscapeUriString and Uri.EscapeDataString which can be used to URL-encode portions of a URI such as query strings and path components and such.

Even in the desktop framework, you should never take a dependency on System.Web.dll just for HttpUtility, although many developers still do it. This is bad for 3 reasons.

  • The assembly is very large and loading it can add significant delays to your application.
  • You will be bloating the working set of your process for about 20 lines of code.
  • It makes your application require the full framework since System.Web is not in the client profile.

In addition to the Uri escaping methods described above, if you need HtmlEncode, I would just rip code off that someone else wrote and drop it in your application.
