How to post to user's wall from application's name? - c#

I tried to post to users wall using application access token but it still posts from users name. Is it possible to post from application's name?
var fbc = new FacebookWebClient();
var wc = new WebClient();
var tokenStr = wc.DownloadString(string.Format("https://graph.facebook.com/oauth/access_token?client_id={0}&client_secret={1}&grant_type=client_credentials",
FacebookApplication.Current.AppId, FacebookApplication.Current.AppSecret));
fbc.AccessToken = tokenStr.Replace("access_token=", string.Empty);
dynamic parameters = new ExpandoObject();
parameters.message = "testMessage";
//parameters.link = pageLink;
parameters.name = "testCaption";
dynamic result = fbc.Post(string.Format("{0}/feed", userID), parameters);

var fbPost = new FacebookClient ( accessToken );
dynamic result = fbPost.Post ( "me/feed", new { message = "Welcome to C# SDK and me" } );

Unable to update graph application based subscription with C#

I am trying to update the subscription expiry for my graph token. This is an application based subscription.
This is what I have tried:
var tokenExpiry = DateTime.UtcNow.AddMinutes(4230).ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ss.0Z");
Lookup lp = new Lookup();
string access_token = "{MYACCESSTOKEN}";
_CreateRequestBody requestBody = new _CreateRequestBody
{
expirationDateTime = tokenExpiry
};
RestClient rc = new RestClient();
rc.EndPoint = "https://graph.microsoft.com/v1.0/subscriptions/" + subscriptionId;
rc.AccessToken = access_token;
rc.Method = HttpVerbs.PATCH;
rc.PostData = JsonConvert.SerializeObject(requestBody);
Error message is Invalid: expirationDateTime and its value must be included in the payload.

List<dynamic> listDynamic = new List<dynamic>();
listDynamic.Add(new

backdated_time = datePost,
backdated_time_granularity = "none",
hide_from_newsfeed = false
});
var jsonString = JsonConvert.SerializeObject(listDynamic);

Google Analytics Api 400 Bad Request

I want to import data from Google Analytics.
var gas = new AnalyticsService(auth);
var r = gas.Data.Ga.Get("ga:6332XXXX", "2013-02-01", "2013-02-11", "ga:visits");
r.Dimensions = "ga:date";
r.Sort = "ga:visits";
r.StartIndex = 1;
var data = r.Fetch();
I get 400 bad request error in Fetch method. What is the wrong of my code?
My full code like following:
var scope = AnalyticsService.Scopes.AnalyticsReadonly.ToString();
var clientId = "--------.apps.googleusercontent.com";
var keyFile = #"C:\-----------------privatekey.p12";
var keyPassword = "notasecret";
var desc = GoogleAuthenticationServer.Description;
var key = new X509Certificate2(keyFile, keyPassword, X509KeyStorageFlags.Exportable);
var client = new AssertionFlowClient(desc, key)
{
ServiceAccountId = clientId,
Scope = scope
};
var auth = new OAuth2Authenticator<AssertionFlowClient>(client, AssertionFlowClient.GetState);
var gas = new AnalyticsService(auth);
var r = gas.Data.Ga.Get("ga:6332XXXX", "2013-02-01", "2013-02-11", "ga:visits");
r.Dimensions = "ga:date";
r.Sort = "ga:visits";
r.StartIndex = 1;
var data = r.Fetch();
Thaks for your interest.
A couple of ideas:
your clientId should be your SERVICE ACCOUNT EMAIL (not id)
your scope should be "https://www.googleapis.com/auth/analytics.readonly"
