Question

我有2个应用程序，一个将简单的文本文件上传到Skydrive，另一个用于检索它。我上传位工作正常，但我怎么得到文件ID从SkyDrive下载相同的文件？：（

我尝试使用http://wp.qmatteoq.com/backup-and-restore-on-skydrive-in-windows-phone/中的一些代码，但对于WP8，他们已经删除了GetAsycn（）上的事件处理程序

任何帮助都一如既往地受到赞赏

对于任何感兴趣的人来说，这是多么棘手的代码......这就是你如何做到的：

// This button reads the file from skydrive and puts it into isolated storage
private async void Button_Click(object sender, RoutedEventArgs e)
{
    string id = string.Empty;
    LiveOperationResult result = await this.client.GetAsync("me/skydrive/files");

    List<object> items = result.Result["data"] as List<object>;

    foreach (object item in items)
    {
        IDictionary<string, object> file = item as IDictionary<string, object>;
        if (file["name"].ToString() == "somefile.txt")
        {
            id = file["id"].ToString();
        }
    }

    MessageBox.Show(id.ToString());

    LiveDownloadOperationResult result2 = await client.DownloadAsync(string.Format("{0}/content", id));
    Stream stream = result2.Stream;
    using (IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForApplication())
    {
        using (IsolatedStorageFileStream fileToSave = storage.OpenFile("foo.txt", FileMode.Create, FileAccess.ReadWrite))
        {
            stream.CopyTo(fileToSave);
            stream.Flush();
            stream.Close();
        }
    }
}

从skydrive获取文件ID
