Remarks
For more info, see Quickstart: Reading and writing files, which shows how to read and write bytes to a file by using a RandomAccessStream. To encode an image by using a stream, see Imaging.
Properties
CanRead |
Gets a value that indicates whether the stream can be read from. |
CanWrite |
Gets a value that indicates whether the stream can be written to. |
Position |
Gets the byte offset of the stream. |
Size |
Gets or sets the size of the random access stream. |
Methods
CloneStream() |
Creates a new instance of a IRandomAccessStream over the same resource as the current stream. |
Dispose() |
Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. |
FlushAsync() |
Flushes data asynchronously in a sequential stream. (Inherited from IOutputStream) |
GetInputStreamAt(UInt64) |
Returns an input stream at a specified location in a stream. |
GetOutputStreamAt(UInt64) |
Returns an output stream at a specified location in a stream. |
ReadAsync(IBuffer, UInt32, InputStreamOptions) |
Reads data from the stream asynchronously. (Inherited from IInputStream) |
Seek(UInt64) |
Sets the position of the stream to the specified value. |
WriteAsync(IBuffer) |
Writes data asynchronously in a sequential stream. (Inherited from IOutputStream) |
