IRandomAccessStream IRandomAccessStream IRandomAccessStream IRandomAccessStream IRandomAccessStream Interface

Definition

Supports random access of data in input and output streams.

public : interface IRandomAccessStream : IClosable, IInputStream, IOutputStream
struct winrt::Windows::Storage::Streams::IRandomAccessStream : IClosable, IInputStream, IOutputStream
public interface IRandomAccessStream : IDisposable, IInputStream, IOutputStream
Public Interface IRandomAccessStream Implements IDisposable, IInputStream, IOutputStream
// You can't instantiate an interface directly in JavaScript. You can use objects that implement the interface, however.

Remarks

For more info, see Quickstart: Reading and writing a file, 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 CanRead CanRead CanRead CanRead

Gets a value that indicates whether the stream can be read from.

CanWrite CanWrite CanWrite CanWrite CanWrite

Gets a value that indicates whether the stream can be written to.

Position Position Position Position Position

Gets the byte offset of the stream.

Gets or sets the size of the random access stream.

Methods

CloneStream() CloneStream() CloneStream() CloneStream() CloneStream()

Creates a new instance of a IRandomAccessStream over the same resource as the current stream.
