XmlReader.ReadInnerXmlAsync XmlReader.ReadInnerXmlAsync XmlReader.ReadInnerXmlAsync XmlReader.ReadInnerXmlAsync Method

定义

异步读取所有内容,包括作为字符串的标记。Asynchronously reads all the content, including markup, as a string.

public:
 virtual System::Threading::Tasks::Task<System::String ^> ^ ReadInnerXmlAsync();
public virtual System.Threading.Tasks.Task<string> ReadInnerXmlAsync ();
abstract member ReadInnerXmlAsync : unit -> System.Threading.Tasks.Task<string>
override this.ReadInnerXmlAsync : unit -> System.Threading.Tasks.Task<string>
Public Overridable Function ReadInnerXmlAsync () As Task(Of String)

返回

当前节点中的所有 XML 内容(包括标记)。All the XML content, including markup, in the current node. 如果当前节点没有任何子级,则返回空字符串。If the current node has no children, an empty string is returned.

异常

在上一次异步操作完成之前调用了 XmlReader 方法。An XmlReader method was called before a previous asynchronous operation finished. 在此情况下,会引发 InvalidOperationException 并显示消息“异步操作已在进行中。”In this case, InvalidOperationException is thrown with the message "An asynchronous operation is already in progress."

- 或 --or-

调用了 XmlReader 异步方法,但未将 Async 标志设置为 trueAn XmlReader asynchronous method was called without setting the Async flag to true. 在此情况下,将引发 InvalidOperationException 并显示消息“若要使用 Async 方法,请将 XmlReaderSettings.Async 设置为 True。”In this case, InvalidOperationException is thrown with the message "Set XmlReaderSettings.Async to true if you want to use Async Methods."

注解

这是异步版本ReadInnerXml,具有相同功能。This is the asynchronous version of ReadInnerXml, with the same functionality. 若要使用此方法,必须设置Async标记,用于trueTo use this method, you must set the Async flag to true.
