HttpUtility.UrlEncode in Windows Phone 7?

The regular .Net framework contains HttpUtility.UrlEncode in the System.Web Assembly and in Silverlight it appears it was moved to System.Windows.Browser. But in Windows Phone 7 (which I thought was the same as Silverlight) I can't seem to find a proper way to UrlEncode anything. Neither of the previously mentioned assemblies are available in the Windows Phone 7 environment.

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.

HttpUtility.UrlEncode and HttpUtility.UrlDecode are in Windows Phone 7, they just got moved.

Look for them in System.Net.HttpUtility in assembly System.Windows.dll.
