Output​Stream​Over​Stream Output​Stream​Over​Stream Output​Stream​Over​Stream Class

Definition

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

public : sealed class OutputStreamOverStream : IClosable, IOutputStreampublic sealed class OutputStreamOverStream : IDisposable, IOutputStreamPublic NotInheritable Class OutputStreamOverStream Implements IDisposable, IOutputStream
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()

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
Attributes

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
Attributes

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 )
Returns
IAsyncOperation<PlatForm::Boolean> IAsyncOperation<bool> IAsyncOperation<bool>

The stream flush operation.

Attributes

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)

Writes data asynchronously in a sequential stream.

public : IAsyncOperationWithProgress<unsigned short, unsigned short> WriteAsync(IBuffer buffer)public IAsyncOperationWithProgress<uint, uint> WriteAsync(IBuffer buffer)Public Function WriteAsync(buffer As IBuffer) As IAsyncOperationWithProgress( Of uint, uint )
Parameters
buffer
IBuffer IBuffer IBuffer

The buffer into which the asynchronous writer operation writes.

Returns
IAsyncOperationWithProgress<unsigned short, unsigned short> IAsyncOperationWithProgress<uint, uint> IAsyncOperationWithProgress<uint, uint>

The byte writer operation.
