I have an ASP.NET/C# application. In a method in one of the business object classes, I need to make an HttpWebRequest to a website that returns an XML response. I need to URL-encode the request, but the System.Web namespace in an ".cs" business object class does not include the needed HttpUtility class that it does in the System.Web namespace if called directly from the ".aspx.cs" code-behind. I could hack a work-around to pass the string value back to the .aspx.cs page and then pass the url-encoded value back to the .cs class, but that doesn't seem very elegant, and I don't think that I should have to, since I may need to use this method from other places.
So, my question is, where do I find a UrlEncode method that I can use?
