开发Windows Phone 8应用程序。我得到一个例外。无法将类型为“System.Boolean”的对象强制转换为“System.Collections.Generic.IDictionary” [英] developing a windows phone 8 application. I am getting An exception. Unable to cast object of type 'System.Boolean' to type 'System.Collections.Generic.IDictionary

问题描述

我集成了facebook SDK，我这样做是为了在墙上发布数据

I integrated facebook SDK, I am doing this to post data on the wall

FacebookClient fb = new FacebookClient(App.AccessToken);

           fb.PostCompleted += (o, e) =>
           {
               if (e.Error != null)
               {
                   Dispatcher.BeginInvoke(() => MessageBox.Show(e.Error.Message));
                   return;
               }

              var result = (IDictionary<string, object>)e.GetResultData();

               Dispatcher.BeginInvoke(() =>
               {
                   MessageBox.Show("Posted Open Graph Action, id: " + (string)result["id"], "Result", MessageBoxButton.OK);

               });
           };

但是获得例外，

异常类型'System.InvalidCastException'在fbtest.DLL中发生但未在用户代码中处理



附加信息：无法将类型为'System.Boolean'的对象强制转换为输入'System.Collections.Generic.IDictionary`2 [System.String，System.Object]'。

But getting exception,
An exception of type 'System.InvalidCastException' occurred in fbtest.DLL but was not handled in user code

Additional information: Unable to cast object of type 'System.Boolean' to type 'System.Collections.Generic.IDictionary`2[System.String,System.Object]'.
