In the parameters list, you have to provide the image source by either of the following:
url : a valid url to the image
source: iamge data
[Code]
[HttpPost]
public ActionResult PostPhotoOnWall(HttpPostedFileBase file)
{
var filename = Path.GetFileName(file.FileName);
 StreamResourceInfo sri = null;
Uri jpegUri = new Uri(filename, UriKind.Relative);
sri = Application.GetResourceStream(jpegUri);
byte[] imageData = new byte[sri.Stream.Length];
sri.Stream.Read(imageData, 0, System.Convert.ToInt32(sri.Stream.Length));
var client = new FacebookClient();
// Post to user's wall
var postparameters = new Dictionary<string, object>();
var media = new FacebookMediaObject
{
FileName = filename,
ContentType = "image/jpeg"
};
media.SetValue(imageData);
postparameters["source"] = media;
postparameters["access_token"] = Session["access_token"].ToString();
var result = client.Post("/me/photos", postparameters);
return View("PostPhoto");
}
