My facebook codes for creating new events is here;

FacebookClient facebookClient = new FacebookClient(accessToken);
Dictionary<string, object> createEventParameters = new Dictionary<string, object>();
createEventParameters.Add("name", "test");
createEventParameters.Add("start_time", DateTime.Now.ToUniversalTime().ToString("yyyyMMdd"));
createEventParameters.Add("end_time", DateTime.Now.AddDays(2).AddHours(4).ToUniversalTime().ToString("yyyyMMdd"));
createEventParameters.Add("owner", "me");
createEventParameters.Add("description", "description");
JsonObject venueParameters = new JsonObject();
venueParameters.Add("street", "test");
venueParameters.Add("city", "test");
venueParameters.Add("state", "test");
venueParameters.Add("zip", "0000");
venueParameters.Add("country", "test");
venueParameters.Add("latitude", "100.0");
venueParameters.Add("longitude", "100.0");
createEventParameters.Add("venue", venueParameters);
createEventParameters.Add("privacy", "OPEN");
createEventParameters.Add("location", "test");
FacebookMediaObject logo = new FacebookMediaObject(){
   ContentType = "image/jpeg",
   FileName = @"J:\logo.jpg"
};
logo.SetValue(System.IO.File.ReadAllBytes(logo.FileName));
createEventParameters.Add("picture", logo);
JsonObject result = facebookClient.Post("/my_page_Id/events", createEventParameters) as JsonObject;

The code seems o.k to me but it does not upload the cover photo and I don't know why.

My sample code;

createEventParameters.Add("cover_url", "photo_url");

and this post Facebook C# SDK, Create Event With Picture doesnt work for me.

Could you please help me.

Thanks

You cannot upload the cover pic while creating an event. You can upload the cover pic only after the event is created. So, two calls instead of one!

Follow these steps:

  1. Create the event without any parameter related to cover pic. After the call, you'll get the Event ID in response.

  2. Use that Event ID and make this call-

    API: \POST /{event-id}

    Parameter: cover_url (picture link)

That's it!

  • var cover_args = new Dictionary(); var coverfile = new FacebookMediaObject { ContentType = PostItem.ImageList[0].Type, FileName = Path.GetFileName(attachementPath) }.SetValue(System.IO.File.ReadAllBytes(attachementPath)); cover_args["cover_url"] = coverfile; cover_args["access_token"] = FacebookPage.PageToken; var CoverResult = fbClient.Post(resultId, cover_args); But it's not working. – user3207150 May 20 '14 at 13:31
