XmlWriter.WriteAttributesAsync(XmlReader, Boolean) XmlWriter.WriteAttributesAsync(XmlReader, Boolean) XmlWriter.WriteAttributesAsync(XmlReader, Boolean) XmlWriter.WriteAttributesAsync(XmlReader, Boolean) Method

定義

非同步寫出在 XmlReader 中的目前位置找到的所有屬性。Asynchronously writes out all the attributes found at the current position in the XmlReader.

public:
 virtual System::Threading::Tasks::Task ^ WriteAttributesAsync(System::Xml::XmlReader ^ reader, bool defattr);
public virtual System.Threading.Tasks.Task WriteAttributesAsync (System.Xml.XmlReader reader, bool defattr);
abstract member WriteAttributesAsync : System.Xml.XmlReader * bool -> System.Threading.Tasks.Task
override this.WriteAttributesAsync : System.Xml.XmlReader * bool -> System.Threading.Tasks.Task
Public Overridable Function WriteAttributesAsync (reader As XmlReader, defattr As Boolean) As Task

參數

reader
XmlReader XmlReader XmlReader XmlReader

要複製屬性的 XmlReaderThe XmlReader from which to copy the attributes.

defattr
Boolean Boolean Boolean Boolean

若要從 true 複製預設屬性,則為 XmlReader,否則為 falsetrue to copy the default attributes from the XmlReader; otherwise, false.

傳回

表示非同步 WriteAttributes 作業的工作。The task that represents the asynchronous WriteAttributes 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WriteAttributes,使用相同的功能。This is the asynchronous version of WriteAttributes, 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.
