Hi Frederik,

Check out this post, think it will do the trick:  http://our.umbraco.org/forum/developers/api-questions/7993-Get-URL-of-media-file#comment29410

-Tom

The sample Tom refers to uses the Media api which is pretty slow. I recommend you use library.GetMedia because it uses the umbraco cache system. You can read all the data from the XPathNodeIterator which GetMedia returns. Here is a sample

//Get the media item from the umbraco cache.
XPathNodeIterator mediaIterator = library.GetMedia(nodeId, false);

//Convert the XPathNodeIterator to an XDocument.
XDocument xmlDocument = XDocument.Parse(mediaIterator.Current.OuterXml);

//Get the root element.
XElement mediaElement = xmlDocument.Root;

string mediaUrl = GetMediaLink(mediaElement)

/// <summary>
/// Return the media link of an element.
/// </summary>
/// <param name="mediaElement"></param>
/// <returns></returns>
public static string GetMediaLink(XElement mediaElement)
{
    XElement filePathElement = DigibizMediaHelper.GetFilePathElement(mediaElement);

    if (filePathElement == null)
    {
        return "#";
    }

    return filePathElement.Value;
}

/// <summary>
/// Get the file path element. If the old xml schema is used we need to fetch this a different way.
/// </summary>
/// <param name="mediaElement"></param>
/// <returns></returns>
public static XElement GetFilePathElement(XElement mediaElement)
{
    XElement filePathElement = 
        !UmbracoSettings.UseLegacyXmlSchema
        ?
        mediaElement.Descendants("umbracoFile").FirstOrDefault()
        :
        mediaElement.Descendants("data").Where(x => x.Attribute("alias").Value == "umbracoFile").FirstOrDefault()
        ;

    if (filePathElement == null)
    {
        //If the filepath is not found try another option.
        filePathElement =
            !UmbracoSettings.UseLegacyXmlSchema
            ?
            mediaElement.Descendants("fileName").FirstOrDefault()
            :
            mediaElement.Descendants("data").Where(x => x.Attribute("alias").Value == "fileName").FirstOrDefault()
            ;
    }

    if (filePathElement == null)
    {
        //If the filepath is still not found try a third option.
        filePathElement =
            !UmbracoSettings.UseLegacyXmlSchema
            ?
            mediaElement.Descendants("file").FirstOrDefault()
            :
            mediaElement.Descendants("data").Where(x => x.Attribute("alias").Value == "file").FirstOrDefault()
            ;
    }

    return filePathElement;
}

This is how I do it in the Digibiz Advanced Media Picker.
