以下是如何在asp.net winforms中从Facebook获取用户信息的快速示例。此示例使用Facebook SDK for .Net。此代码段使用Facebook登录用户，然后获取额外的用户信息，但也可用于获取额外的个人资料数据。

static string Facebook_Key = "yourAppID";
static string Facebook_Secret = "yourAppSecret";

protected void Page_Load(object sender, EventArgs e)
{
    //check if the user is returning from Facebook
    if (Request.QueryString["code"] != null)
    {
        FacebookClient fbc = new FacebookClient();

        //retreive the access token
        dynamic result = fbc.Post("oauth/access_token", new
        {
            client_id = Facebook_Key,
            client_secret = Facebook_Secret,
            redirect_uri = Request.Url.AbsoluteUri,
            code = Request.QueryString["code"].ToString()
        });

        fbc.AccessToken = result.access_token;

        //get the extra profile data
        dynamic user = fbc.Get("me?fields=first_name,last_name,id,email");

        //display the results
        FacebookLoginLabel.Text += user.id + "<br>";
        FacebookLoginLabel.Text += user.first_name + "<br>";
        FacebookLoginLabel.Text += user.last_name + "<br>";
        FacebookLoginLabel.Text += user.email + "<br>";

        //start the actual aspnet registration or login
        LoginOrRegisterUser();
    }
}

protected void FacebookLoginButton_Click(object sender, EventArgs e)
{
    FacebookClient fbc = new FacebookClient();

    //start the Facebook login request
    var loginUrl = fbc.GetLoginUrl(new
    {
        client_id = Facebook_Key,
        redirect_uri = Request.Url.AbsoluteUri,
        response_type = "code",
        scope = "email"
    });

    //redirect the user to Facebook for authentication
    Response.Redirect(loginUrl.AbsoluteUri);
}

ASPX

<asp:Button ID="FacebookLoginButton" runat="server" Text="Log in with Facebook" OnClick="FacebookLoginButton_Click" />

<asp:Label ID="FacebookLoginLabel" runat="server" Text=""></asp:Label>
