Asynchronously closes any open elements or attributes and puts the writer back in the Start state.
public:
virtual System::Threading::Tasks::Task ^ WriteEndDocumentAsync();
public virtual System.Threading.Tasks.Task WriteEndDocumentAsync ();
abstract member WriteEndDocumentAsync : unit -> System.Threading.Tasks.Task
override this.WriteEndDocumentAsync : unit -> System.Threading.Tasks.Task
Public Overridable Function WriteEndDocumentAsync () As Task
Returns
The task that represents the asynchronous WriteEndDocument
operation.
Exceptions
An XmlWriter method was called before a previous asynchronous operation finished. In this case, InvalidOperationException is thrown with the message "An asynchronous operation is already in progress."
-or-
An XmlWriter asynchronous method was called without setting the Async flag to true
. In this case, InvalidOperationException is thrown with the message "Set XmlWriterSettings.Async to true if you want to use Async Methods."
Remarks
This is the asynchronous version of WriteEndDocument, with the same functionality. To use this method, you must set the Async flag to true
.
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 WriteEndDocument().
