Facebook权限错误

Question

public Form1()
        {
            InitializeComponent();

            // The application key of the Facebook application used
            fbService.ApplicationKey = "XXXXXXXXXXX";

            // Add all needed permissions
            List<Enums.ExtendedPermissions> perms = new List<Enums.ExtendedPermissions>
            {
               Enums.ExtendedPermissions.none
        };
            fbService.ConnectToFacebook(perms);   //error here (The given key was not present in the dictionary.)         
        }

我提到错误，我收到错误，因为我是facebook api的新手，特别是c＃的新手，任何解释的答案都是appriciated 谢谢

Answer 1

在FacebookClient上使用静态方法，如下所示：

FacebookClient.SetDefaultHttpWebRequestFactory(uri => {
    var request = new HttpWebRequestWrapper((HttpWebRequest)WebRequest.Create(uri));
    request.Proxy = ......; // normal .net IWebProxy
    return request;
});
