Constructors

InMemoryRandomAccessStream()

Creates a new instance of the InMemoryRandomAccessStream class.

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.

Close()

Closes the current stream and releases system resources.

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

FlushAsync()

Flushes data asynchronously in a sequential stream.

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)

Returns an asynchronous byte reader object.

Seek(UInt64)

Sets the position of the stream to the specified value.

WriteAsync(IBuffer)

Writes data asynchronously in a sequential stream.
