在url下面,用户的Facebook页面直到昨天.但它不再起作用了.
https://www.facebook.com/app_scoped_user_id/xxxxxxxxxxxxx/
有没有办法获取用户的Facebook页面或出于安全原因被禁用?
我确定这是一个非常基本的问题,但我无法在谷歌找到任何解决方案.
当我试图使用该代码块时,它会抛出一个异常,即'System.Activities.Statements.TransactionScope':在using语句中使用的类型必须可以隐式转换为'System.IDisposable'
using (TransactionScope trans = new TransactionScope())
{
}
简单地说,我想在Linq代码中使用TransactionScope.
感谢和问候
