StorageFile.CreateStreamedFileFromUriAsync Method

Definition

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)
Public Shared Function CreateStreamedFileFromUriAsync (displayNameWithExtension As String, uri As Uri, thumbnail As IRandomAccessStreamReference) As IAsyncOperation(Of StorageFile)

Parameters

displayNameWithExtension
String

Platform::String

winrt::hstring

The user-friendly name of the StorageFile to create, including a file type extension.

uri
Uri Uri

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

thumbnail
IRandomAccessStreamReference

The thumbnail image for the StorageFile to create.

For a high-quality thumbnail, one edge of this thumbnail should be at least 1024 pixels.

Returns

When this method completes, it returns a StorageFile object that represents the Uniform Resource Identifier (URI) resource.

Attributes

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.
