WP7 Skydrive API -创建文件夹不工作

本文关键字：文件夹 工作 创建 Skydrive API WP7 | 更新日期: 2023-09-27 18:08:03

我试着从我的WP7应用程序在skydrive上创建一个新文件夹。

下面是我的代码: 
    private void MSAccountLoginToggleSwitch_Checked_1(object sender, RoutedEventArgs e)
    {
        try
        {
            LiveAuthClient auth = new LiveAuthClient("** my id **");
            auth.LoginAsync(new string[] { "wl.skydrive_update", "wl.calendars_update" });
            auth.LoginCompleted += auth_LoginCompleted;
        }
        catch (LiveAuthException exception)
        {
            MessageBox.Show("Error signing in: " + exception.Message);
        }
    }
    private void auth_LoginCompleted(object sender, LoginCompletedEventArgs e)
    {
        if (e.Status == LiveConnectSessionStatus.Connected)
        {
            mySession = e.Session;
        }
        else
        {
            MSAccountLoginToggleSwitch.IsChecked = false;
        }
    }
    private void Button_Click_1(object sender, RoutedEventArgs e)
    {
        try
        {
            var folderData = new Dictionary<string, object>();
            folderData.Add("some test", "A brand new folder was created");
            LiveConnectClient liveClient = new LiveConnectClient(mySession);
            liveClient.PostAsync("me/skydrive", folderData);
        }
        catch (LiveConnectException exception)
        {
            MessageBox.Show("Error creating folder: " + exception.Message);
        }
        finally
        {
            MessageBox.Show("uploded");
        }
    }

它显示消息框"上传"，但当我看我的skydrive文件没有创建。

它没有显示任何错误信息，我做错了什么?

WP7 Skydrive API -创建文件夹不工作

这行liveClient.PostAsync("me/skydrive", folderData);给了您一个任务，您不需要等待，您只需在最后显示MessageBox.Show("uploded");。我认为WP7中不支持async/await，因此您需要使用ContinueWith方法处理任务:

private void Button_Click_1(object sender, RoutedEventArgs e)
{
        var folderData = new Dictionary<string, object>();
        folderData.Add("some test", "A brand new folder was created");
        LiveConnectClient liveClient = new LiveConnectClient(mySession);
        liveClient.PostAsync("me/skydrive", folderData)
                  .ContinueWith((t) => 
                                 { 
                                    if (t.IsFauled)
                                    {
                                       MessageBox.Show("Error creating folder: " + t.Exception.Message);
                                    }
                                    else
                                    {
                                        MessageBox.Show("uploded");  
                                    }
                                 }
                                , TaskScheduler.FromCurrentSynchronizationContext());
}

已更新:上面的代码将只在WP8上工作，但在WP7上PostAsync不是任务的方法，所以要获得PostAsync结果，你需要订阅PostCompleted事件。

我发现了问题，我有错误的行:

folderData.Add("some test", "A brand new folder was created");

正确的版本是:

folderData.Add("name", "some test");

   var folderData = new Dictionary<string,object>();
   folderData.Add("myfolder ","simple folder ");    
   client.PostAsync("me/skydrive","{'name': 'myfolder' }"); 
 client.PostCompleted += new EventHandler<LiveOperationCompletedEventArgs>          (client_PostCompleted);
   void client_PostCompleted(object sender, LiveOperationCompletedEventArgs e)
    {
        var a = e.RawResult;
    }
