CODE REVIEW At your website project, Add reference to Facebook.dll and to Facebook.WebControls.dll. At the .cs code file write the following: new protected void Page_Load(object sender, EventArgs e) { base.Api = “Your Application key”; //Inform which application to use. base.Secret = “Your Application Secret”; //Added encryption for security. base.Page_Load(sender, e); //must be called if (!IsPostBack) { //Use Facebook API to pull data from Facebook. Facebook.Entity.User user = this.FBService.GetUserInfo(); Collection<Facebook.Entity.User> friends = this.FBService.GetFriends(); } }

At your website project, Add reference to Facebook.dll and to Facebook.WebControls.dll.

At the .cs code file write the following:

new protected void Page_Load(object sender, EventArgs e)

{

base.Api = “Your Application key”; //Inform which application to use.

base.Secret = “Your Application Secret”; //Added encryption for security.

base.Page_Load(sender, e); //must be called

if (!IsPostBack) {

//Use Facebook API to pull data from Facebook.

Facebook.Entity.User user = this.FBService.GetUserInfo();

Collection<Facebook.Entity.User> friends = this.FBService.GetFriends();

}

}

CODE REVIEW (CONTD.) Now we can use the data from Facebook in our application. Let’s first build a simple page in ASP.Net This page declares two labels that will be rendered in the server-side, and a link to another page. Pay attention to the ID attr. of the asp:labels, we will use these IDs now.

This page declares two labels that will be rendered in the server-side, and a link to another page.

Pay attention to the ID attr. of the asp:labels, we will use these IDs now.

CODE REVIEW (CONTD.) Now we need to insert the data we pulled from Facebook platform into our web page. lblHelloWorld.Text = &quot;Hello &quot; + user.Name + &quot; you have &quot; + friends.Count + &quot; friends + &quot;...&quot; + this.FBService.SessionKey; this.FBService.SetFBML(&quot;Hello &quot; + u.Name + &quot; you have &quot; + f.Count + &quot; friends”); //Set FBML method sets an FBML string to the profile page. lblDashboard.Text = &quot;<fb:dashboard><fb:action href=&quot;http://apps.facebook.com/aspnetcanvasfbml/default3.aspx&quot;> Go to Default3 </fb:action></fb:dashboard><br/>&quot;; //Sets FBML dashboard element to the applcication That’s all you need to create an application
