Definition

Replaces the contents of the file referred to by the specified IStorageFile object with a new data stream of the specified Uniform Resource Identifier (URI). This method lets the app download the data on-demand when the StorageFile that represents the stream is first accessed.

The data stream is accessed through the StorageFile that is returned and the data is downloaded on-demand when the StorageFile is first accessed.

Replaces the IStorageFile object that represents the specified file with a new StorageFile that provides a stream of the specified Uniform Resource Identifier (URI).

Parameters

fileToReplace
IStorageFile IStorageFile IStorageFile

The file that the created StorageFile will provide a stream of.

uri
Uri Uri Uri

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

thumbnail
IRandomAccessStreamReference IRandomAccessStreamReference 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 streamed file. Subsequently, this StorageFile object should be used to access file content instead of the file (type IStorageFile ) that was specified to be replace.
