XmlWriter.WriteNameAsync(String) 方法

定义

异步写出指定的名称,确保它是符合 W3C XML 1.0 建议 (https://www.w3.org/TR/1998/REC-xml-19980210#NT-Name)) 的有效名称。Asynchronously writes out the specified name, ensuring it is a valid name according to the W3C XML 1.0 recommendation (https://www.w3.org/TR/1998/REC-xml-19980210#NT-Name).

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

参数

name
String

要写入的名称。The name to write.

返回

Task

表示 WriteName 异步操作的任务。The task that represents the asynchronous WriteName operation.

例外

在上一次异步操作完成之前调用了 XmlWriter 方法。An XmlWriter 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 XmlWriter 异步方法,但未将 Async 标志设置为 trueAn XmlWriter asynchronous method was called without setting the Async flag to true. 在这种情况下,将引发 InvalidOperationException 并显示消息“如果要使用异步方法,请将 XmlWriterSettings.Async 设置为 true”。In this case, InvalidOperationException is thrown with the message "Set XmlWriterSettings.Async to true if you want to use Async Methods."

注解

这是的异步版本 WriteName ,具有相同的功能。This is the asynchronous version of WriteName, with the same functionality. 若要使用此方法,必须将 Async 标志设置为 trueTo use this method, you must set the Async flag to true.
