Facebook C# SDK - Post to wall - c#

I'm developing an asp.net MVC 3 Facebook app and I am trying to post a message to my wall. Here is my code:
FacebookWebClient client = new FacebookWebClient();
// Post to user's wall
var postparameters = new Dictionary<string, object>();
postparameters["message"] = "Hello world!";
postparameters["name"] = "This is a name";
postparameters["link"] = "http://thisisalink.com;
postparameters["description"] = "This is a description";
var result = client.Post("/me/feed", postparameters);
I can get the access token using client.AccessToken, so I'm assuming I don't have to set it anywhere. This code produces no errors and for the result I get an ID. However, when I bring up my Facebook, I see nothing on my wall nor in my news feed. I'm not sure what I'm missing. I've looked at related questions here at StackOverflow, but I see no reports/questions similar to mine. I've also tried changing the code based on what I've seen in other posts, but to no avail. I also checked my Facebook account settings and I see my application listed with permission to post to my wall. I also tried posting a message to my wall via the Graph API explorer and I'm getting the same result. I get an ID in return, but when I check my Facebook account I see nothing. At been at this for a couple of days. Any help would be greatly appreciated.
Thanks in advance.
[EDIT]
I wonder if something is wrong with my app generated access_token. Using this access_token, as I mentioned in my post, I get the same result using the Graph API explorer. An ID is returned, but no message on my wall. However, if I give the Graph API explorer permission to post to my wall and use its own generated access_token, I can successfully post a message using the explorer. Here's the FB login button code:
<div>
<h1>Login using Facebook</h1>
<p><fb:login-button perms="user_location, publish_stream, email"></fb:login-button></p>
</div>

Basically you need to add an additional parameter into your post parameters.
args["access_token"] = account.access_token;
this is the token of the specific page.
I wont repeat the code, follow here for example: Post On Facebook Page As Page Not As Admin User Using Facebook C# SDK
(second answer)

Did you request right App permissions to Facebook in your action method?
Try: [CanvasAuthorize(Permissions = "user_location, publish_stream, email")]

Did you append the access_token to the URL? See example here. It's also documented here (see Using the Access Token).
/me/feed?access_token=<access_token>

with one small change, your code works fine for me. you have to pass the users auth token into the constructor like this...
var client = new FacebookClient(accessToken);
// Post to user's wall
var postparameters = new Dictionary<string, object>();
postparameters["message"] = "Hello world!";
postparameters["name"] = "This is a name";
postparameters["link"] = "http://thisisalink.com;
postparameters["description"] = "This is a description";
var result = client.Post("/me/feed", postparameters);
this method works for me, although i am not sure which facebook sdk you are using.
i'm using http://facebooksdk.net/ its quite good so if you're not using it i would recommend it

Facebook : No permission to publish the video

I am trying to upload video using c# facebook graph api, and its working fine for user development account, i am able to post on wall, but when i try to other user i am getting error :
(OAuthException - #100) (#100) No permission to publish the video
This is my sample code
**var fb = new Facebook.FacebookClient(token);
dynamic parameters = new ExpandoObject();
parameters.source = new Facebook.FacebookMediaObject { ContentType = "video/mp4", FileName = "video.mp4" }.SetValue(File.ReadAllBytes(#"D:\home\site\wwwroot\\Videos\abc.mp4"));
parameters.title = "test title";
parameters.description = "test description";
dynamic result = fb.Post("/me/videos", parameters);**
where i set the permission
**scope=publish_actions**
Please help me, Thank you in Advance.
In order to make publish_actions work for other users without a role in the App, you need to go through Login Review. Everything you need to know about that is in the docs: https://developers.facebook.com/docs/facebook-login/review
If you are indeed trying with an App Admin/Developer/Tester and it still does not work, debug the Access Token in the Debugger and make sure publish_actions is authorized correctly: https://developers.facebook.com/tools/debug/

How to post media on google plus through google api?

private void googleplue()
{
Moment body = new Moment();
ItemScope itemScope = new ItemScope();
itemScope.Id = "replacewithuniqueforaddtarget";
itemScope.Image = "http://www.google.com/s2/static/images/GoogleyEyes.png";
itemScope.Type = "";
itemScope.Description = "The description for the action";
itemScope.Name = "An example of add activity";
body.Object = itemScope;
body.Type = "http://schema.org/AddAction";
MomentsResource.InsertRequest insert =
new MomentsResource.InsertRequest(
plusService,
body,
userId,
MomentsResource.Collection.Vault);
// Moment wrote = insert.Fetch();
}
I tried this but not work please give me any other solution.
Moment isn't the same as posting to Google+ timeline its not possible to post to the Google+ timeline. see Issue 41: Write access to the streams
In order to post moments which isn't the same thing, you need to be able to set request_visible_actions as part of the authentication process and it doesn't appear that its possible to do with with the current version of the C# client library see
If you want to post moments and not write to a user time line then your going to have to figure out how to send the request_visible_actions as part of your authentication. if you do figure out how to do that please post the answer on my question.

Trying to post photos to Facebook using Facebook C# SDK returns exception "Facebook.FacebookOAuthException"

I am trying to upload photo to a page I have created. Unfortunately it returns me the following exception - A first chance exception of type 'Facebook.FacebookOAuthException' occurred in Facebook.dll.
You'd think that I have missed some permission in the "Graph API Explorer", but I have actually checked every single one of them and I am using that Access Token. Obviously the problem is connected to the Access Token, but I am not sure how.
Here is what I have tested and it works fine:
Posting messages on my personal wall
Posting photos in my personal album
Posting messages on my page
And yet when I try to post photos to my page album or to my page wall it returns me that exception.
I use the code from here:
FacebookClient facebookClient = new FacebookClient(accessToken);
dynamic parameters = new ExpandoObject();
parameters.access_token = accessToken;
parameters.source = new FacebookMediaObject
{
FileName = "My_Picture.jpg",
ContentType = "image/jpeg"
}.SetValue(File.ReadAllBytes(#"F:\\My_Picture.jpg"));
//"my" album ID is 12345
//page album id is 67890
facebookClient.Post("/67890/photos", parameters);
I have tried changing /photos to /feed, but it doesn't work either. I have also tried changing the 67890 (album ID) with my page name and page id.
I use VS 2013, C# with WPF, newest version of Facebook SDK C#.
So I reset the permissions and now everything works properly*.
*What I was looking for was posting the photo on the page as the page. Right now the code above posts a photo on the page as a normal user.

how to post on facebook wall for specific list of users using asp.net c#?

I am trying to post on specific group of users on facebook such as (close friends, or family, or college friend...) and I used the code bellow.
code that I used:
1
FacebookClient fpost1 = new FacebookClient(access_token);
fpost1.Post("/1234567890/feed", new { message = "test post"});
note: access_token is working correctly when I am doing some job before this exception.
I put my friendlist id instead of 1234567890, that you can get it from graph .../me?fields=friendlists
it did not work and gave me this error "(OAuthException - #2) An unexpected error has occurred. Please retry your request later."
2
FacebookClient fpost1 = new FacebookClient(access_token);
fpost1.Post("/me/feed", new { message = "it is very cold.", to="1234567890"});
this one work, but it post to "only me" as target.
thank you
It looks to me that what you are doing here...
FacebookClient fpost1 = new FacebookClient(access_token);
fpost1.Post("/1234567890/feed", new { message = "test post"});
is wrong. Because I believe that 1234567890 is a user-id, right? Not a friendslist-id. According to the documentation this edge/endpoint signature goes like....
/{user-id}/feed
where user-id is obviously a user id. The documentation states that...
Most nodes in the Graph API have edges that can be published to (such as Photos or Posts). All Graph API publishing is done simply with an HTTP POST request to the relevant endpoint with any necesssary parameters included. For example, if you wanted to publish a post on behalf of someone, you would make an HTTP POST request as below:
POST graph.facebook.com
/{user-id}/feed?
message={message}&
access_token={access-token}
Notice that it says "On Behalf of Someone". My understanding is that you are publishing on behalf of someone and to do that, this someone must have requested an access_token through your application. In other words, if this user hasn't logged in to your app and generated a valid access token you cannot publish on his/her wall
POST graph.facebook.com
me/feed?message="hello"&privacy={"value": "CUSTOM", "allow": "1234567890"}
where the 1234567890 is one of friendlists id

Simple C# Evernote API OAuth example or guide?

Anybody know where I can find a simple example C# code example? Apparently really tough to find.
I'm just starting out, got my Developer key.
Initial (really noob question/presumption) - -Can (should/must) my solution be a web service client? No new libraries I need to install in .Net right?
Basically, as a test, I want to be able to securely present a single note from a private notebook in html similar to what the Everfort export in html looks like on a outside WebSite.
Many Thanks in Advance!
You should start by downloading our API ZIP from http://www.evernote.com/about/developer/api/. You'll find C# client sample code in /sample/csharp. This sample code demonstrates using the Evernote API from a desktop application that authenticates using username and password.
I am not sure if you ever got this working, but I was playing around with Evernote, OpenAuth and C# this morning and managed to get it all working. I have put together a blog post / library explaining the experience and outlining how to do it with MVC here - http://www.shaunmccarthy.com/evernote-oauth-csharp/ - it uses the AsyncOAuth library: https://github.com/neuecc/AsyncOAuth
I wrote a wrapper around AsyncOAuth that you might find useful here: https://github.com/shaunmccarthy/AsyncOAuth.Evernote.Simple
One prickly thing to be aware of - the Evernote Endpoints (/oauth and /OAuth.action) are case sensitive
// Download the library from https://github.com/shaunmccarthy/AsyncOAuth.Evernote.Simple
// Configure the Authorizer with the URL of the Evernote service,
// your key, and your secret.
var EvernoteAuthorizer = new EvernoteAuthorizer(
"https://sandbox.evernote.com",
"slyrp-1234", // Not my real id / secret :)
"7acafe123456badb123");
// First of all, get a request token from Evernote - this causes a
// webrequest from your server to Evernote.
// The callBackUrl is the URL you want the user to return to once
// they validate the app
var requestToken = EvernoteAuthorizer.GetRequestToken(callBackUrl);
// Persist this token, as we are going to redirect the user to
// Evernote to Authorize this app
Session["RequestToken"] = requestToken;
// Generate the Evernote URL that we will redirect the user to in
// order to
var callForwardUrl = EvernoteAuthorizer.BuildAuthorizeUrl(requestToken);
// Redirect the user (e.g. MVC)
return Redirect(callForwardUrl);
// ... Once the user authroizes the app, they get redirected to callBackUrl
// where we parse the request parameter oauth_validator and finally get
// our credentials
// null = they didn't authorize us
var credentials = EvernoteAuthorizer.ParseAccessToken(
Request.QueryString["oauth_verifier"],
Session["RequestToken"] as RequestToken);
// Example of how to use the credential with Evernote SDK
var noteStoreUrl = EvernoteCredentials.NotebookUrl;
var noteStoreTransport = new THttpClient(new Uri(noteStoreUrl));
var noteStoreProtocol = new TBinaryProtocol(noteStoreTransport);
var noteStore = new NoteStore.Client(noteStoreProtocol);
List<Notebook> notebooks = client.listNotebooks(EvernoteCredentials.AuthToken);
http://weblogs.asp.net/psteele/archive/2010/08/06/edamlibrary-evernote-library-for-c.aspx might help. As the author states it just bundles some and fixes some. Haven't tried it myself but thought I'd mention for a possibly easier way to get started. Possibly.
This might help too...found it using the Way Back Machine since the original blog site was offline.
