Decoding an input stream

Question

So I have a page that is accepting XML through a POST method. Here's a small bit of the code:

if (Request.ContentType != "text/xml")
        throw new HttpException(500, "Unexpected Content Type");

StreamReader stream = new StreamReader(Request.InputStream);
string x = stream.ReadToEnd();  // added to view content of input stream

XDocument xmlInput = XDocument.Load(stream);

I was getting an error, so I converted the stream to a string, just to see if everything was being sent correctly. When I looked at the content, it looked like this:

%3c%3fxml+version%3d%271.0%27+encoding%3d%27UTF-8%27%3f%3e%0d%0a

So I guess I need to decode the stream. The only problem is that I don't know how I can use HtmlDecode on the stream, and still keep it as a StreamReader object.

Is there any way to do this?

Apparently the client is sending the content as URL-encoded XML. So you need to decode the content like this:

StreamReader stream = new StreamReader(Request.InputStream);
string x = stream.ReadToEnd();
string xml = HttpUtility.UrlDecode(x);

XDocument xmlInput = XDocument.LoadXml(xml);

Anyway, the problem is probably on the client side... why is it encoding the XML this way?
