public System.Threading.Tasks.ValueTask CloseAsync (long errorCode, System.Threading.CancellationToken cancellationToken = default);member this.CloseAsync : int64 * System.Threading.CancellationToken -> System.Threading.Tasks.ValueTaskPublic Function CloseAsync (errorCode As Long, Optional cancellationToken As CancellationToken = Nothing) As ValueTaskParameters
- errorCode
- Int64
An application-provided code with the reason for closure.
- cancellationToken
- CancellationToken
A cancellation token that can be used to cancel the asynchronous operation.
Returns
An asynchronous task that completes when the connection is closed.
Exceptions
The cancellation token was canceled. This exception is stored into the returned task.
Remarks
Closing the connection is not graceful in regards to its streams. Calling CloseAsync(Int64, CancellationToken) will immediately close all streams associated with this connection. Make sure that all streams have been closed and all their data consumed before calling this method. Otherwise, all the data that was received but not yet consumed will be lost.
If CloseAsync(Int64, CancellationToken) is not called before disposing the connection, the DefaultCloseErrorCode will be used by DisposeAsync() to close the connection.
