XmlReader.ReadEndElement 方法

定义

命名空间:

System.Xml

程序集:

System.Xml.ReaderWriter.dll

Source:

XmlReader.cs

检查当前内容节点是否为结束标记并将读取器推进到下一个节点。

public:
 virtual void ReadEndElement();

public virtual void ReadEndElement ();

abstract member ReadEndElement : unit -> unit
override this.ReadEndElement : unit -> unit

Public Overridable Sub ReadEndElement ()

例外

XmlException

当前节点不是一个结束标记，或者如果在输入流中遇到不正确的 XML。

InvalidOperationException

在上一次异步操作完成之前调用了 XmlReader 方法。 在此情况下，会引发 InvalidOperationException 并显示消息“异步操作已在进行中。”

示例

以下示例显示每个元素的文本内容。

using (XmlReader reader = XmlReader.Create("book3.xml")) {

  // Parse the XML document.  ReadString is used to
  // read the text content of the elements.
  reader.Read();
  reader.ReadStartElement("book");
  reader.ReadStartElement("title");
  Console.Write("The content of the title element:  ");
  Console.WriteLine(reader.ReadString());
  reader.ReadEndElement();
  reader.ReadStartElement("price");
  Console.Write("The content of the price element:  ");
  Console.WriteLine(reader.ReadString());
  reader.ReadEndElement();
  reader.ReadEndElement();
}

Using reader As XmlReader = XmlReader.Create("book3.xml")               
  ' Parse the XML document.  ReadString is used to 
  ' read the text content of the elements.
  reader.Read()
  reader.ReadStartElement("book")
  reader.ReadStartElement("title")
  Console.Write("The content of the title element:  ")
  Console.WriteLine(reader.ReadString())
  reader.ReadEndElement()
  reader.ReadStartElement("price")
  Console.Write("The content of the price element:  ")
  Console.WriteLine(reader.ReadString())
  reader.ReadEndElement()
  reader.ReadEndElement()            
End Using

该示例使用 book3.xml 文件。

<book>
  <title>Pride And Prejudice</title>
  <price>19.95</price>
</book>
