Facebook ASP.NET编码问题（试图让CodePlex示例正常工作）

我正在尝试让以下代码正常工作：

Imports Microsoft.VisualBasic  
Imports System
Imports System.Data
Imports System.Configuration
Imports System.Web
Imports System.Web.Security
Imports System.Web.UI
Imports System.Web.UI.WebControls
Imports System.Web.UI.WebControls.WebParts
Imports System.Web.UI.HtmlControls
Imports System.Collections.ObjectModel
Imports Facebook
Imports Facebook.WebControls

Public Partial Class _Default
    Inherits CanvasIFrameBasePage
    Private Const FACEBOOK_API_KEY As String = "xxxxxxxxxx"
    Private Const FACEBOOK_SECRET As String = "yyyyyyyyyy"

    Shadows Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
        MyBase.Api = FACEBOOK_API_KEY
        MyBase.Secret = FACEBOOK_SECRET
        MyBase.Page_Load(sender, e)

        If (Not IsPostBack) Then
            Try
                ' Use the FacebookService Component to populate Friends
                Dim u As Facebook.Entity.User = Me.FBService.GetUserInfo()

                Dim f As Collection(Of Facebook.Entity.User) = Me.FBService.GetFriends()


                Dim s As String = ""
                If f.Count <> 1 Then
                    s = "s"
                End If
                lblHelloWorld.Text = "Hello " & u.Name & " you have " & f.Count & " friend" & s & "..." & Me.FBService.SessionKey
                Me.FBService.SetFBML("Hello " & u.Name & " you have " & f.Count & " friend" & s)
            Catch e1 As Exception
                'Throw
            End Try
        End If
    End Sub
End Class

有人能帮忙吗

它被称为Facebook Toolkit，位于

，您可能需要指定您正在从Codeplex使用的Facebook客户端API。谢谢Kurt。。。它是Facebook工具包，位于

Dim u As Facebook.Entity.User = Me.FBService.GetUserInfo()
