member this.AppendAsync : System.IO.Stream * System.Threading.CancellationToken -> System.Threading.Tasks.Task
Public Function AppendAsync (stream As Stream, Optional cancellationToken As CancellationToken = Nothing) As Task
Parameters
- stream
- Stream
The data to process.
- cancellationToken
- CancellationToken
The token to monitor for cancellation requests. The default value is None.
Returns
A task that represents the asynchronous append operation.
Exceptions
stream
is null
.
The cancellation token was canceled. This exception is stored into the returned task.
Remarks
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 Append(Stream).
