how to post html content in facebook fan page

Dictionary<string, string=""> data = new Dictionary<string, string="">();

data.Add("message", "i like ");
FaceBookConnect.Post(ViewState["Code"].ToString(), "me/feed", data);

FacebookClient doesn't work in your case because you are using .NET 3.5 but the version of that dll is not supporting your dot net version.So use such dll which is for 3.5.And for rest see http://forums.asp.net/t/1613185.aspx/1

Is it possible to log in
Facebook from asp.net passing the user credentials and then automatically post message from asp.net webform ?

You can see..http://www.overpie.com/aspnet/articles/csharp-post-message-to-facebook.cshtml, http://stackoverflow.com/questions/6494865/auto-facebook-oauth-from-asp-net-c-sharp

Thank You for posting :) but they have used FacebookClient .I have the dll but i cant use it(This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.)
this error comes if i use it
i am getting the access token
static string GetAccessToken(string apiId, string apiSecret)
{
string AuthenticationUrlFormat = "https://graph.facebook.com/oauth/access_token?client_id={0}&client_secret={1}&grant_type=client_credentials&scope=manage_pages,offline_access,publish_stream";

string accessToken = string.Empty;
string url = string.Format(AuthenticationUrlFormat, apiId, apiSecret);

WebRequest request = WebRequest.Create(url);
WebResponse response = request.GetResponse();

using (Stream responseStream = response.GetResponseStream())
{
StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
String responseString = reader.ReadToEnd();

NameValueCollection query = HttpUtility.ParseQueryString(responseString);

accessToken = query["access_token"];
}

if (accessToken.Trim().Length == 0)
throw new Exception("There is no Access Token");

return accessToken;
}

You need to find .NET 3.5 version FacebookClient dll,when you use that all should be ok.

i am trying to find that dll but not able to get it

ridoy 10-Aug-13 3:19am

Download it nuget.org/api/v2/package/Facebook, then extract it,go to lib folder,now see there is a folder named net35-client,double click it and see Facebook.dll there. Use that in your project.

I have the FaceBook.dll in my solution what i want is FacebookClient dll

ridoy 10-Aug-13 3:49am

You don't read my links well for what you can't catch up things,do you read http://www.overpie.com/aspnet/articles/csharp-post-message-to-facebook.cshtml carefully?Look they use Facebook.dll not FacebookClient.And you will find FacebookClient class inside Facebook.dll.

rocky_em 10-Aug-13 3:53am

i tried that Facebook.FacebookClient its not available FacebookClient does not pops up
