Answer 3

看看你可以使用Facebook SDK的地方

Answer 4

If you only want to check if the account exists and is valid, you could check if the page contains a certain text that only appears on valid Facebook accounts. Create a webBrowser class and have the user log into their account, then download the page source as a HTML file and check for text in it. This is a big workaround but from my point of view it works.
