StorageFile.CreateStreamedFileFromUriAsync Method

Definition

Namespace:

Windows.Storage

Creates a StorageFile to represent a stream of data from the specified Uniform Resource Identifier (URI) resource. This method lets the app download the data on-demand when the StorageFile that represents the stream is first accessed.

public:
 static IAsyncOperation<StorageFile ^> ^ CreateStreamedFileFromUriAsync(Platform::String ^ displayNameWithExtension, Uri ^ uri, IRandomAccessStreamReference ^ thumbnail);

/// [Windows.Foundation.Metadata.RemoteAsync]
 static IAsyncOperation<StorageFile> CreateStreamedFileFromUriAsync(winrt::hstring const& displayNameWithExtension, Uri const& uri, IRandomAccessStreamReference const& thumbnail);

[Windows.Foundation.Metadata.RemoteAsync]
public static IAsyncOperation<StorageFile> CreateStreamedFileFromUriAsync(string displayNameWithExtension, System.Uri uri, IRandomAccessStreamReference thumbnail);

function createStreamedFileFromUriAsync(displayNameWithExtension, uri, thumbnail)

uri

Uri Uri

The Uniform Resource Identifier (URI) of the resource used to create the StorageFile.

RemoteAsyncAttribute

Remarks

This method is nearly equivalent to CreateStreamedFileAsync, except when using this method, the system provides a StreamedFileDataRequestedHandler on the app's behalf and implements this function to download the specified Uri into the streamed file.
