我正在使用http://www.codeproject.com/KB/IP/Facebook_API.aspx

我试图调用使用WPF创建的XAML.但它给了我一个错误:

调用线程必须是STA,因为许多UI组件都需要这个.

我不知道该怎么办.我想这样做:

FacebookApplication.FacebookFriendsList ffl = new FacebookFriendsList();

但它给了我这个错误.

我添加了一个后台工作者:

static BackgroundWorker bw = new BackgroundWorker();

static void Main(string[] args)
{
    bw.DoWork += bw_DoWork;
    bw.RunWorkerAsync("Message to worker");
    Console.ReadLine();
}

static void bw_DoWork(object sender, DoWorkEventArgs e)
{
    // This is called on the worker thread
    FacebookApplication.FacebookFriendsList ffl = new FacebookFriendsList();

    Console.WriteLine(e.Argument);        // Writes "Message to worker"

    // Perform time-consuming task...
}

我正在创建一个xps文档,如下所示.

Assembly assembly = Assembly.GetExecutingAssembly();
//read embedded xpsDocument file
Stream helpStream = assembly.GetManifestResourceStream(resourceNameOfContext);
if (helpStream != null)
{
    Package package = Package.Open(helpStream);
    string inMemoryPackageName = "memorystream://" + topicName + ".xps";
    Uri packageUri = new Uri(inMemoryPackageName);
    //Add package to PackageStore
    PackageStore.AddPackage(packageUri, package);
    docXps = new XpsDocument(package, CompressionOption.Maximum, inMemoryPackageName);
}
return docXps;

当我想要获取docXps.GetFixedDocumentSequence(); 我收到了上述错误.有人可以帮忙吗？

谢谢,
