Can we post pictures/videos or links on friends wall using facebook SDK c#?
i am using it in winforms .I am using this SDK
https://github.com/facebook/csharp-sdk
public static void PostToWall(string wallPost, string friendId)
{
var fb = new FacebookClient(Globals.AccessToken);
var parameters = new Dictionary<string, object>();
parameters["message"] = wallPost;
fb.PostAsync(String.Format("{0}/feed", friendId), parameters);
}
If you want to post it to the wall of the user logged in, use:
fb.PostAsync("me/feed", parameters);
You must have your application user grant stream_publish extended permissions then you may use the Graph API to publish to friends' streams.
It's recommended to use PostTaskAsync instead of obsolete PostAsync method of FacebookClient. The parameters remain the same.

I want to use C# to make friend with uid=14650247412 base on graph API
https://graph.facebook.com/me/friends/14650247412?access_token=EAAAxxx&method=post
But I don't know how to implement in C#, could you please help me do it?
I'm using Facebook from Nudget package
var client = new FacebookClient();
string uid = "14650247412";
dynamic parameters = {};
client.AccessToken = "EAAxxx";
var result = client.Post("https://graph.facebook.com/me/friends/" + uid , parameters);
the result is empty data
data = {}
Could you please show me how to do it? Thanks a lots
No. Adding friends is not possible through the API.
However, you can direct users to the webpage http://www.facebook.com/addfriend.php?id=[USER UID]
Where [USER UID] is a valid facebook user id.
Use WebBrowser control in a form dialog to achieve this.
I'm working on a UWP app and I was thinking about moving from the old LiveSDK (which is discontinued and was last updated around 2015) to the new OneDriveSDK (the Graph APIs), specifically using the UWP Community Toolkit Services package and its APIs.
The library seems pretty easy to use as far as login and files/folders management go, but so far I haven't been able to find a way to retrieve the user full name, the user email and the profile picture.
Here's the code I'm currently using to do so, using LiveSDK (code simplified here):
public static async Task<(String username, String email)> GetUserProfileNameAndEmailAsync(LiveConnectSession session)
{
LiveConnectClient connect = new LiveConnectClient(session);
LiveOperationResult operationResult = await connect.GetAsync("me");
IDictionary<String, object> results = operationResult.Result;
String username = results["name"] as String;
if (!(results["emails"] is IDictionary<string, object> emails)) return default;
String email = emails["preferred"] as String ?? emails["account"] as String;
return (username, email);
}
public static async Task<ImageSource> GetUserProfileImageAsync([NotNull] LiveConnectSession session)
{
LiveConnectClient liveClient = new LiveConnectClient(session);
LiveOperationResult operationResult = await liveClient.GetAsync("me/picture");
String url = operationResult.Result?["location"] as String;
// The URL points to the raw image data for the user profile picture, just download it
return default;
}
I've looked at the guide here and I see there seems to be a replacement for all of the above, but I haven't been able to integrate that with the UWP Toolkit service. For example, to retrieve the user info, here's what I've tried:
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, "https://graph.microsoft.com/v1.0/me/");
await OneDriveService.Instance.Provider.AuthenticationProvider.AuthenticateRequestAsync(request);
using (HttpResponseMessage response = await OneDriveService.Instance.Provider.HttpProvider.SendAsync(request))
{
String content = await response.Content.ReadAsStringAsync();
}
But this fails with an exception at the SendAsync call.
NOTE: I know there are the Graph APIs too in the UWP Toolkit, with ready-to-use methods to retrieve the user info and profile picture, but apparently you need an office 365 subscription to use those APIs (both as a dev, and probably as a user too), so I guess that's not what I'm looking for here, since I've always been able to retrieve these info using a normal OneDrive client.
Is there a way to do this on UWP, either through some method within the UWP Toolkit, or with some other solution?
Thanks!
EDIT: I've reused the code from the sample app, registered my app to get a clientID and made a quick test, but it's not working as expected and I'm getting this exception:
Fixed, see below
EDIT #2: According to this question, I had to switch to https://graph.microsoft.com/beta to get the profile picture, as the 1.0 version of the APIs doesn't support it for normal MS accounts right now. All things considered, it seems to be working just fine now 👍
I followed the MSDN document to register my app for Microsoft Graph. After that, I will get an application ID(in API, it's called as clientId).
Then, I used the Microsoft Graph Connect Sample for UWP to login in with my general MS account. It worked well. I could get the username, email etc.
Please note that if you want to run this sample successfully, you would need to use the application ID to initialize the PublicClientApplication object in AuthenticationHelper.cs.
public static PublicClientApplication IdentityClientApp = new PublicClientApplication("your client id");
I got the following question. When I place a status message for an user, I would like to add my Facebook page as reference. I have seen other posts where the tag "via" is placed under the capitation.
How do I achieve that?
I am using the C# SDK from Facebook. I am already able to post with the following code:
FacebookClient fbClient = new FacebookClient(accessToken);
var args = new Dictionary<string, object>();
args["place"] = objectFBID;
fbClient.Post("/me/feed", args);
What parameter is needed for the "via" tag. I tried the "from" parameter, however it didn't work!
Thanks in advance!
When posting on a wall, make sure the user has given the right permissions to the App. Otherwise alot of data is hidden. This was the case with my facebook account. When using a facebook account that has given full acces, all data is displayed.
i have created desktop Facebook application using c# .net. i want to retrieve users message,post and chat history. which is convenient way to retrieve users all information.i have started with Facebook Graph API but i am not getting any example.
can any one help me ?
A bit late to the party but anyway:
Add a reference to System.Net.Http and Newtonsoft.Json
string userToken = "theusertokentogiveyoumagicalpowers";
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("https://graph.facebook.com");
HttpResponseMessage response = client.GetAsync($"me?fields=name,email&access_token={userToken}").Result;
response.EnsureSuccessStatusCode();
string result = response.Content.ReadAsStringAsync().Result;
var jsonRes = JsonConvert.DeserializeObject<dynamic>(result);
var email = jsonRes["email"].ToString();
}
Go to developer.facebook.com -> Tools & Support -> Select Graph API Explorer
Here U get FQL Query, Access Token
Then write code in C#.....
var client = new FacebookClient();
client.AccessToken = Your Access Token;
//show user's profile picture
dynamic me = client.Get("me?fields=picture");
pictureBoxProfile.Load(me.picture.data.url);
//show user's birthday
me = client.Get("me/?fields=birthday");
labelBirthday.Text = Convert.ToString(me.birthday);

I hope this will help you.!!!
you can check the Graph explorer tool on Developer.facebook.com , go to Tools and select graph explorer, its a nice tool which gives you exact idea about what you can fetch by sending "GET" and "POST" method on FB Graph APis
From what i see the app now only uses webhooks to post data to a data endpoint (in your app) at which point you can parse and use this. (FQL is deprecated). This is used for things like messaging.
A get request can be send to the API to get info - like the amt. of likes on your page.
The docs of FB explain the string you have to send pretty nicely. Sending requests can be done with the webclient, or your own webrequests.
https://msdn.microsoft.com/en-us/library/bay1b5dh(v=vs.110).aspx
Then once you have a string of the JSON formatted page you can parse this using JSON.NET library. It's available as a NUGEt package.
As per this link code from stack overflow i have try this code for getting
friendslist but after login i got this error "requires valid signature"
string APIKey = ConfigurationManager.AppSettings["API_Key"];
string APISecret = ConfigurationManager.AppSettings["API_Secret"];
Facebook.Session.ConnectSession connectsession = new Facebook.Session.ConnectSession(APIKey, APISecret);
Facebook.Rest.Api api = new Facebook.Rest.Api(connectsession);
var friends = api.Friends.GetLists();
foreach (var friend in friends)
{
System.Console.WriteLine(friend.name);
}
guide me to find out the solution
Thanks

If you are starting with a new application, you should definitely use the Graph API and not the old Rest API. The Rest API has been deprecated for quite a while now and there is no guarantee how much longer Facebook will support it.
For an example on using the Graph API try http://csharpsdk.org/docs/web/getting-started
You can obtain the friends list by making a request to me/friends
You can test other requests using the Graph API explorer.
