C# code to retrieve xml data

Question

Based on the this sourcecode I'm not able to retrieve the data from the API into XDocument.

I retrieve the error message

{"The remote server returned an error: (400) Bad Request."}

Question:
I don't know what to do?

XDocument xml = XDocument.Parse(new
WebClient().DownloadString("http://api.arbetsformedlingen.se/af/v0/platsannonser/matchning?lanid=1&kommunid=180&yrkesid=2419&1&antalrader=10000"));

What errors are you getting? Some more information would help. — Erik Karlstrand, Jun 06 '15 at 13:30

You need to send HTTP headers:

using (WebClient client = new WebClient())
{
    client.Headers.Add("Accept-Language", " en-US");
    client.Headers.Add("Accept", "application/xml");
    client.Headers.Add("User-Agent", "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)");

    XDocument xml = XDocument.Parse(client.DownloadString("http://api.arbetsformedlingen.se/af/v0/platsannonser/matchning?lanid=1&kommunid=180&yrkesid=2419&1&antalrader=10000"));
}

The server is returning XML, and that is the format that the OP is expecting. So I would change the Accept header to just `"application/xml"`. – Kal Jun 06 '15 at 13:43
The code is working but I retrieve another eroror message "{System.Xml.XmlException} {"Data at the root level is invalid. Line 1, position 1."}". I need to add a new message in Stackoverflow. Thank you for your help! – KLN Jun 06 '15 at 14:41
