我正试图在用户的Facebook墙上发布。我必须使用c#在asp.net中完成。有人有工作项目吗?需要一步一步的帮助。我尝试了几个项目而没有成功。我正在尝试的当前项目在第一次发布后返回400错误请求错误。 所以,我再说一遍,我需要一个不会返回错误而不是网站名称的工作项目, 谢谢, 阿德里安

这是提问者(transportinoradea): 好吧,最后我使用Facebook Api加上另一种方法而不是CallRequest<>这给了我400错误。现在我处理了,一切都好。

我不知道是否有人为asp或c#编写了一个Facebook API,但你不能只用基本的HTTP请求吗?

来自http://developers.facebook.com/docs/reference/api/

“您可以使用访问令牌向相应的连接URL发出HTTP POST请求,从而发布到Facebook图表。”
