Question

在我的WP8.1 Silverlight应用程序中，我想下载一个文件并将其保存到独立存储中。下载没问题，但我怎么能保存呢？

下载时，我用这个：

 var HttpClientDownloadFile = new Windows.Web.Http.HttpClient();

        Windows.Web.Http.HttpRequestMessage request = new Windows.Web.Http.HttpRequestMessage(Windows.Web.Http.HttpMethod.Get, new Uri(downloadUrl));
        request.Headers.Add("Range", "bytes=0-");

        // Hook up progress handler.
        Progress<HttpProgress> progressCallback = new Progress<HttpProgress>(OnSendRequestProgress);
        var tokenSource = new CancellationTokenSource();
        Windows.Web.Http.HttpResponseMessage response = await HttpClientDownloadFile.SendRequestAsync(request).AsTask(tokenSource.Token, progressCallback);

如果我运行调试，在response.content中我有下载。现在，我想将它保存到隔离存储中。我怎样才能做到这一点？我应该使用流吗？

将您的回复转换为流并将其写入文件

using (var fileStream = await this.storageFile.OpenFileAsync(fileName, FileMode.OpenOrCreate))
{      
    await stream.CopyToAsync(fileStream);
}

下载并保存HttpRequestMessage C＃
