vs2008 c#：Facebook非常简单的初学者应用程序

我只是尝试了下一页的说明，让非常基本的应用程序工作，但它不工作。有人试过这个吗

在下一行

friendList1.Friends = facebookService1.Friends.GetUserObjects();

我得到以下错误：

微软脸谱API能工作吗？我是在浪费时间吗？

你看到这个了吗

它假设您只了解Facebook和C#

的基本知识，并考虑针对您遇到的问题发布另一个问题，以及错误消息的确切措辞。也许这很简单。为了帮助你：你能提供一些关于你所做的事情的信息（通过扩展/编辑问题），包括错误消息吗？API有什么问题？你的问题很模糊。需要更多信息的副本。。。到底是什么不起作用？什么错误？我刚刚添加了以下4行，链接中的教程可以正常工作。字符串apikey=“xxxxxxxxxxxxxx”；facebookService1.ApplicationKey=apikey；facebookService1.ConnectToFacebook（）；friendList1.Friends=FaceBookService 1.Friends.GetUserObjects（）；
