CryptoStream.FlushAsync Method (CancellationToken)

.NET Framework 4.5

Clears all buffers for the current stream asynchronously, causes any buffered data to be written to the underlying device, and monitors cancellation requests.

Namespace:  System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)

abstract FlushAsync : 
        cancellationToken:CancellationToken -> Task  
override FlushAsync : 
        cancellationToken:CancellationToken -> Task

Parameters

cancellationToken
Type: System.Threading.CancellationToken

The token to monitor for cancellation requests. The default value is None.

Return Value

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

ExceptionCondition
ObjectDisposedException

The stream has been disposed.

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 with Async and Await (C# and Visual Basic).

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