OutputStreamOverStream OutputStreamOverStream OutputStreamOverStream OutputStreamOverStream Class

Definition

Provides a Windows Runtime output stream for an IStream base implementation.

public : sealed class OutputStreamOverStream : IClosable, IOutputStream
public sealed class OutputStreamOverStream : IDisposable, IOutputStream
Public NotInheritable Class OutputStreamOverStream Implements IDisposable, IOutputStream
// This class does not provide a public constructor.
Attributes
Windows 10 requirements
Device family
Windows 10 (introduced v10.0.10240.0)
API contract
Windows.Foundation.UniversalApiContract (introduced v1)

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() Close() Close() Close()

Closes the current stream and releases system resources.

public : void Close()
This member is not implemented in C#
This member is not implemented in VB.Net
outputStreamOverStream.close();

Dispose() Dispose() Dispose() Dispose()

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

This member is not implemented in C++
void Dispose()
Sub Dispose
void Dispose()

FlushAsync() FlushAsync() FlushAsync() FlushAsync()

Flushes data asynchronously in a sequential stream.

public : IAsyncOperation<Platform::Boolean> FlushAsync()
public IAsyncOperation<bool> FlushAsync()
Public Function FlushAsync() As IAsyncOperation( Of bool )
Windows.Storage.Streams.OutputStreamOverStream.flushAsync().done( /* Your success and error handlers */ );
Returns

The stream flush operation.

Remarks

The FlushAsync method may produce latencies and does not always guarantee durable and coherent storage of data. It's generally recommended to avoid this method if possible.

WriteAsync(IBuffer) WriteAsync(IBuffer) WriteAsync(IBuffer) WriteAsync(IBuffer)

Writes data asynchronously in a sequential stream.

public : IAsyncOperationWithProgress<unsigned int, unsigned int> WriteAsync(IBuffer buffer)
public IAsyncOperationWithProgress<uint, uint> WriteAsync(IBuffer buffer)
Public Function WriteAsync(buffer As IBuffer) As IAsyncOperationWithProgress( Of uint )( Of uint )
Windows.Storage.Streams.OutputStreamOverStream.writeAsync(buffer).done( /* Your success and error handlers */ );
Parameters
buffer
IBuffer IBuffer IBuffer IBuffer

The buffer into which the asynchronous writer operation writes.

Returns

The byte writer operation.
