c# - CreateStreamedFileFromUriAsync : How can i pass a IRandomAccessStreamReference?

我正在尝试使用 StorageFile 方法 CreateStreamedFileFromUriAsync 下载文件，但我对 IRandomAccessStreamReference 参数感到困惑。如何传递 IRandomAccessStreamReference？它是一个接口(interface)。我该怎么办？

public static IAsyncOperation<StorageFile> CreateStreamedFileFromUriAsync(
    string displayNameWithExtension,
    Uri uri,
    IRandomAccessStreamReference thumbnail
)

最佳答案

我找到了答案:

IRandomAccessStreamReference thumbnail =
    RandomAccessStreamReference.CreateFromUri(new Uri(remoteUri));
IAsyncOperation<StorageFile> file1 =
    StorageFile.CreateStreamedFileFromUriAsync("duyuru.pdf", new Uri(remoteUri), thumbnail);
