I'm trying to grab file paths from a ListBoxItem collection and send them via WebClient. Here is the code I'm using:

private void UploadSelectedImages(ListBox.ObjectCollection objectCollection)
{
    foreach (var photo in objectCollection)
	{
        using (var w = new WebClient())
        {
            var values = new NameValueCollection
            {
                { "key", "<my api here>" },
                { "image", Convert.ToBase64String(File.ReadAllBytes(photo.ToString())) }
            };

            XDocument response = new XDocument(w.UploadValues("http://imgur.com/api/upload.xml", values));
            string name = photo.ToString();
            string smallThumbnail = (string)response.Root.Element("small_thumbnail");
            string actualImage = (string)response.Root.Element("original_image");

            UploadedImage image = new UploadedImage(name, smallThumbnail, actualImage);
            uploadedImages.Add(image);
        }
	}

    foreach (var uploadedImage in uploadedImages)
    {
        MessageBox.Show(uploadedImage.ActualImage);
    }
}

I receive this error when creating the XDocument object. Any ideas on what could be wrong?

I guess my question is [b]How can I convert a byte[] response to an XML document?

The root entry in your XML document has something in it. IIRC, it can't have attributes or text in it, only elements.

how about this?

That link isn't really useful because it shows how to create a new XDocument from a Dictionary. I need to convert a byte[] 'response' to a string, which will then be loaded to an Xdocument.

[eclipsed4utoo]

how about this...

UTF8Encoding enc = new UTF8Encoding();
string temp = enc.GetString(w.UploadValues("http://imgur.com/api/upload.xml", values));
XDocument response = Xdocument.Parse(tmp);

This will convert the byte array to it's string representation. This is assuming that the data coming back is simply a byte array of XML data.

Thanks, your post gave me a great idea.
