调用线程必须是STA，因为很多UI组件都需要这个 [英] The calling thread must be STA, because many UI components require this

问题描述

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

我正在尝试调用使用 WPF.但它给了我一个错误:

I am trying to call the XAML which is created using WPF. But it gives me an error:

调用线程必须是 STA，因为很多 UI 组件都需要这个.

The calling thread must be STA, because many UI components require this.

我不知道该怎么办.我正在尝试这样做:

I don't know what to do. I am trying to do this:

FacebookApplication.FacebookFriendsList ffl = new FacebookFriendsList();

但它给了我那个错误.

我添加了一个后台工作人员:

I added a background worker:

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...
}

推荐答案

尝试从 调度员:

Application.Current.Dispatcher.Invoke((Action)delegate{
      // your code
});
