CryptoStream.FlushAsync(CancellationToken) Method
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Clears all buffers for the current stream asynchronously, causes any buffered data to be written to the underlying device, and monitors cancellation requests.
public:
override System::Threading::Tasks::Task ^ FlushAsync(System::Threading::CancellationToken cancellationToken);
public override System.Threading.Tasks.Task FlushAsync (System.Threading.CancellationToken cancellationToken);
override this.FlushAsync : System.Threading.CancellationToken -> System.Threading.Tasks.Task
Public Overrides Function FlushAsync (cancellationToken As CancellationToken) As Task
- cancellationToken
- CancellationToken
The token to monitor for cancellation requests. The default value is None.
A task that represents the asynchronous flush operation.
The stream has been disposed.
The cancellation token was canceled. This exception is stored into the returned task.
You must preface your call to FlushAsync with the await
(C#) or Await
(Visual Basic) operator to suspend execution of the method until the task is complete. For more information, see Asynchronous programming (C#) or Asynchronous programming with Async and Await (Visual Basic).
If the operation is canceled before it completes, the returned task contains the Canceled value for the Status property.
This method stores in the task it returns all non-usage exceptions that the method's synchronous counterpart can throw. If an exception is stored into the returned task, that exception will be thrown when the task is awaited. Usage exceptions, such as ArgumentException, are still thrown synchronously. For the stored exceptions, see the exceptions thrown by Flush().
