Url Encoding / Decoding In ASP.NET

I noticed in my site logs that quite a few people are searching for how to encode and decode a url in ASP.NET, so I thought today I'd write a short blog on how to do that.

If you are wanting to do this from a WebForm, it's very simple:

Encoding:

encodedUrl = Server.UrlEncode(urlToEncode)

Decoding:

decodedUrl = Server.UrlDecode(urlToDecode)

If you are wanting to encode or decode a url from a project other than a web application, you will need to add a reference to System.Web to your project, and create an instance of a System.Web.HttpServerUtility, like so:

Imports System.Web



Public Class UrlDemoClass

   Public Sub UrlDemo(ByVal url As String)





      Dim o As System.Web.HttpServerUtility

      Dim encodedUrl As String

      Dim decodedUrl As String





      encodedUrl = o.UrlEncode(urL)

      decodedUrl = o.UrlDecode(encodedUrl)

      

   End Sub

End Class

That's it!
