Stream.FlushAsync Method

Definition

Asynchronously clears all buffers for this stream and causes any buffered data to be written to the underlying device.

Overloads

FlushAsync()

Asynchronously clears all buffers for this stream and causes any buffered data to be written to the underlying device.

FlushAsync(CancellationToken)

Asynchronously clears all buffers for this stream, causes any buffered data to be written to the underlying device, and monitors cancellation requests.

FlushAsync()

Source:
Stream.cs
Source:
Stream.cs
Source:
Stream.cs

Asynchronously clears all buffers for this stream and causes any buffered data to be written to the underlying device.

public:
 System::Threading::Tasks::Task ^ FlushAsync();
public System.Threading.Tasks.Task FlushAsync ();
[System.Runtime.InteropServices.ComVisible(false)]
public System.Threading.Tasks.Task FlushAsync ();
member this.FlushAsync : unit -> System.Threading.Tasks.Task
[<System.Runtime.InteropServices.ComVisible(false)>]
member this.FlushAsync : unit -> System.Threading.Tasks.Task
Public Function FlushAsync () As Task

Returns

A task that represents the asynchronous flush operation.

Attributes

Exceptions

The stream has been disposed.

Remarks

If a derived class, such as DeflateStream or GZipStream, does not flush the buffer in its implementation of the Flush method, the FlushAsync method will not flush the buffer.

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().

FlushAsync(CancellationToken)

Source:

public:
 virtual System::Threading::Tasks::Task ^ FlushAsync(System::Threading::CancellationToken cancellationToken);
public virtual System.Threading.Tasks.Task FlushAsync (System.Threading.CancellationToken cancellationToken);
[System.Runtime.InteropServices.ComVisible(false)]

override this.FlushAsync : System.Threading.CancellationToken -> System.Threading.Tasks.Task
Public Overridable Function FlushAsync (cancellationToken As CancellationToken) As Task

Parameters

cancellationToken
CancellationToken

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

Returns

A task that represents the asynchronous flush operation.

Attributes

Exceptions

The stream has been disposed.

The cancellation token was canceled. This exception is stored into the returned task.

Remarks

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

If a derived class, such as DeflateStream or GZipStream, does not flush the buffer in its implementation of the Flush method, the FlushAsync method will not flush the buffer.
