Question

I’m trying to upload photos into Facebook by using MVC3 C#. The code is running successfully but the photos are not uploaded into Facebook. I’m having add ID and App Secret. I tried many ways and for many days I worked hard, but the result is zero. Here is the code of my controller

[HttpPost][HttpGet]

public ActionResult Profile(HttpPostedFileBase file, FacebookOAuthResult facebookOAuthResult) {
  dynamic args = new ExpandoObject();
  args = new Dictionary<string, object>();
  args["message"] = "hi";
  args["picture"] = "http://apps.facebook.com/Uploads/photos";
  string accesstoken=FacebookWebContext.Current.AccessToken;
  FacebookClient fbApp = new FacebookClient(accesstoken);
  try {
    fbApp.Post("MYAPPID" + "/Photos", args);
  } catch (FacebookOAuthException ex) {
            //
  }
  // Verify that the user selected a file
  if (file != null && file.ContentLength > 0) {
    var path1 = Path.Combine(Server.MapPath("~/Content/uppoads"), file.FileName);
    //file.SaveAs(path1);
    fbApp.Post("MYAPPID" + "/photos", path1);
  }
  // redirect back to the index action to show the form once again
  return RedirectToAction("Profile");
}

Could anyone help me to find the solution? Thanks in advance.

You are Post the local path of the photo to Facebook, FB doesn’t know what it is.
You should post the photo as binary in the Post body.

var media = new Facebook.FacebookMediaObject();
var filebytes  = System.IO.File.ReadAllBytes(path1);
media.SetValue(filebytes);
fbApp.Post("248050331932489" + "/photos", media);
