How do you UrlEncode without using System.Web?

Question

I am trying to write a windows client application that calls a web site for data. To keep the install to a minimum I am trying only use dlls in the .NET Framework Client Profile. Trouble is that I need to UrlEncode some parameters, is there an easy way to do this without importing System.Web.dll which is not part of the Client Pofile?

Answer 1

There's a client profile usable version, System.Net.WebUtility class, present in client profile System.dll. Here's the MSDN Link:

WebUtility

Answer 2

You can use

Uri.EscapeUriString (see http://msdn.microsoft.com/en-us/library/system.uri.escapeuristring.aspx)

Answer 3

Here's an example of sending a POST request that properly encodes parameters using application/x-www-form-urlencoded content type:

using (var client = new WebClient())
{
    var values = new NameValueCollection
    {
        { "param1", "value1" },
        { "param2", "value2" },
    };
    var result = client.UploadValues("http://foo.com", values);
}
