UWP-如何在C＃中使用OneDrive API同步文件

我正在创建一个UWP应用程序，并且我想使用Onedrive API，以便用户可以将其文件的副本保存在他们的Onedrive帐户中，但是我没有得到它，到目前为止，我仅设法登录了我想要的东西：

• 上传文件
• 下载文件
• 并进行同步（如果其中任何一个被修改）
• 建立资料夹
• 删除文件

这段代码实现了登录，但是我不能超出此范围，就像继续上传文件或下载它们一样

 private async void btn_Login_Click(object sender, RoutedEventArgs e)
        {
            if (this.oneDriveClient == null)
            {
                try
                {
                    // Setting up the client here, passing in our Client Id, Return Url, 
                    // Scopes that we want permission to, and building a Web Broker to 
                    // go do our authentication. 



                    this.oneDriveClient = await OneDriveClient.GetAuthenticatedMicrosoftAccountClient(
                        clientId,
                        returnUrl,
                        scopes,
                        webAuthenticationUi: new WebAuthenticationBrokerWebAuthenticationUi());



                   // Show in text box that we are connected.
                   txtBox_Response.Text = "We are now connected";

                    // We are either just autheticated and connected or we already connected, 
                    // either way we need the drive button now.
                    btn_GetDriveId.Visibility = Visibility.Visible;
                }
                catch (OneDriveException exception)
                {
                    // Eating the authentication cancelled exceptions and resetting our client. 
                    if (!exception.IsMatch(OneDriveErrorCode.AuthenticationCancelled.ToString()))
                    {
                        if (exception.IsMatch(OneDriveErrorCode.AuthenticationFailure.ToString()))
                        {
                            txtBox_Response.Text = "Authentication failed/cancelled, disposing of the client...";

                            ((OneDriveClient)this.oneDriveClient).Dispose();
                            this.oneDriveClient = null;
                        }
                        else
                        {
                            // Or we failed due to someother reason, let get that exception printed out.
                            txtBox_Response.Text = exception.Error.ToString();
                        }
                    }
                    else
                    {
                        ((OneDriveClient)this.oneDriveClient).Dispose();
                        this.oneDriveClient = null;
                    }
                }
            }
        }

我在github中创建了一个示例存储库：Onedrive Sync Files Sample

我已经尝试过使用Dropbox，Gdrive，但是它对UWP的实现似乎要复杂得多，因此我选择了OneDrive。任何答案都会非常有帮助，谢谢
