Facebook SDK .NET C＃错误消息

Question

I'm trying to connect to facebook using the Facebook SDK in c# to get user details.

FacebookClient client = new FacebookClient();
client.AppId = appId;
dynamic me = client.Get("me");

The error message I am receiving in line 3 is:

A first chance exception of type 'Facebook.FacebookOAuthException' occurred in Facebook.dll

Does anyone know what I did wrong please?

You need to initialise the client with an access token (from the .net sdk):

var fb = new FacebookClient("access_token");

There are various different types of access token, have a look at the facebook dev page for this:
