c# - Post Photos and Videos on Facebook Wall -

-

i need post photos, videos on facebook walls mvc app. i'm getting below error (oauthexception - #2500) active access token must used query information current user.

please me. please find below code i'm using. 

  string appid = string.empty;   string appsecretcode = string.empty;   appid = "<<application id>>";   appsecretcode = "<<app secretcode>>";   var fb = new facebookclient();   dynamic result = fb.get("oauth/access_token", new   {       client_id = appid,       client_secret = appsecretcode,       grant_type = "client_credentials",       scope = "publish_stream"   });   string accesstoken = result.access_token;   var client = new facebookclient(accesstoken);   var postparameters = new dictionary<string, object>();   var media = new facebookmediaobject   {       filename = @"bday.jpg",       contenttype = "image/jpeg"   };   byte[] img = system.io.file.readallbytes(@"c:\users\user\desktop\bday.jpg");   media.setvalue(img);   postparameters["source"] = media;   postparameters["access_token"] = result.access_token;   var result1 = client.post(string.format("https://graph.facebook.com/{0}/photos", "<<user id>>"), postparameters);

you need generate access token https://developers.facebook.com/tools/explorer , try:

required acccountid, pageid  dynamic parameters = new expandoobject(); parameters.message =modellist.message; parameters.subject = modellist.subject; parameters.account_id = modellist.acccountid;  imagebytes =  byte[] of image  parameters.source = new facebookmediaobject{     contenttype = imagetype,     filename = url }.setvalue(imagebytes);  client.post(pageid+ "/photos", parameters);

hope help.
