MemoryStream.FlushAsync Method (CancellationToken)

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

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

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


Public Overrides Function FlushAsync ( _
    cancellationToken As CancellationToken _
) As Task
public override Task FlushAsync(
    CancellationToken cancellationToken


Return Value

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


Exception Condition

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.
