Get public photos from facebook using xamarin.Social

Question

Can anyone help me to get public photos from a Facebook page. I'm developing a mobile app using Xamarin.Forms in which I need to get public photos from Facebook.

Currently I'm using Xamarin.Social to integrate Facebook in the app and I'm able to login into a Facebook account but not able to get public photos.

Use the Xamarin.Auth to query the relative facebook API link. For Example, to get the user name and ID you can use:

var request = new OAuth2Request("GET", new Uri("https://graph.facebook.com/v2.4/me"), null, _currentUser);
            await request.GetResponseAsync().ContinueWith(t =>
                {
                    if (t.IsFaulted)
                        return;
                    else
                    {
                        string mail = t.Result.GetResponseText();
                        Dictionary values = 
                            JsonConvert.DeserializeObject>(mail);
                        bool s = values.TryGetValue("name", out _name); 
                        bool i = values.TryGetValue("id", out _userId);
                        if(!s){
                            _name = "Error Getting Username"; 
                        }
                        if(!i){
                            _userId = "Error Getting Id"; 
                        }
                    }
                });
