Windows phone 7 WP7和Skydrive WaitOne阻止一切

我正在尝试从SkyDrive下载一个文件，并将异步调用包装在一个同步类中。然而，当我打电话给WaitOne时，一切都被屏蔽了，EventHandler从未接到过电话

 _client = new LiveConnectClient(connection.Session);
 _client.GetCompleted += new EventHandler<LiveOperationCompletedEventArgs>(client_GetCompleted);
 _client.GetAsync("me/skydrive/files");

 _autoEvent.WaitOne();  //get's stuck here client_GetCompleted never called.

....


void client_GetCompleted(object sender, LiveOperationCompletedEventArgs e)
{
    ///do stuff
    _autoEvent.Set();
}

---

删除_autoEvent.WaitOne调用，将引发get completed事件。

您很可能正在阻止UI线程。发布更多代码会有所帮助 尝试在新的非ui线程中运行第一部分：

System.Threading.ThreadPool.QueueUserWorkItem(o =>
{
    _client = new LiveConnectClient(connection.Session);
    _client.GetCompleted +=
    new EventHandler<LiveOperationCompletedEventArgs>(client_GetCompleted);
    _client.GetAsync("me/skydrive/files");

   _autoEvent.WaitOne();  //get's stuck here client_GetCompleted never called.

   <other code>
});
