XmlWriter.WriteEndDocumentAsync XmlWriter.WriteEndDocumentAsync XmlWriter.WriteEndDocumentAsync XmlWriter.WriteEndDocumentAsync Method

定義

以非同步的方式關閉任何開啟的項目或屬性,並將寫入器回復開始狀態。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

傳回

表示非同步 WriteEndDocument 作業的工作。The task that represents the asynchronous WriteEndDocument operation.

例外狀況

在先前的非同步作業完成前呼叫了 XmlWriter 方法。An XmlWriter method was called before a previous asynchronous operation finished. 在此情況下,會擲回 InvalidOperationException 與「非同步作業已經在進行中」的訊息。In this case, InvalidOperationException is thrown with the message "An asynchronous operation is already in progress."

-或--or-

在未將 Async 旗標設為 true的情況下呼叫了 XmlWriter 非同步方法。An XmlWriter asynchronous method was called without setting the Async flag to true. 在此情況下,就會擲回 InvalidOperationException 並顯示訊息「如果您要使用非同步方法,請將 XmlWriterSettings.Async 設為 true」。In this case, InvalidOperationException is thrown with the message "Set XmlWriterSettings.Async to true if you want to use Async Methods."

備註

這是非同步的WriteEndDocument,使用相同的功能。This is the asynchronous version of WriteEndDocument, with the same functionality. 若要使用此方法,您必須設定Async旗標設為trueTo use this method, you must set the Async flag to true.
