Remarks

The InputStreamOverStream, OutputStreamOverStream, and RandomAccessStreamOverStream classes are interop helpers to convert between the Windows Runtime stream types, which are natively asynchronous, and the Component Object Model (COM) IStream types, which are natively synchronous.

These helper classes make it easier for to reuse legacy code when you transition to the Windows Runtime stream types.

Methods

Close()

Closes the current stream and releases system resources.
Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
ReadAsync(IBuffer, UInt32, InputStreamOptions)

Returns an asynchronous byte reader object.
