MemoryStream.FlushAsync Method (CancellationToken)

.NET Framework 4.6 and 4.5

Asynchronously clears all buffers for this stream, and monitors cancellation requests.

Namespace:  System.IO
Assemblies:   mscorlib (in mscorlib.dll)
  System.IO (in System.IO.dll)

'Declaration
<ComVisibleAttribute(False)> _
<HostProtectionAttribute(SecurityAction.LinkDemand, ExternalThreading := True)> _
Public Overrides Function FlushAsync ( _
	cancellationToken As CancellationToken _
) As Task

Parameters

cancellationToken
Type: System.Threading.CancellationToken

The token to monitor for cancellation requests.

Return Value

Type: System.Threading.Tasks.Task
A task that represents the asynchronous flush operation.

ExceptionCondition
ObjectDisposedException

The stream has been disposed.

Because any data written to a MemoryStream object is written into RAM, this method is redundant.

If the operation is canceled before it completes, the returned task contains the Canceled value for the Status property.

You can create a cancellation token by creating an instance of the CancellationTokenSource class and passing the Token property as the cancellationToken parameter.

NoteNote

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: ExternalThreading. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.
