XmlReader.ReadEndElement 方法

定義

命名空間:

System.Xml

組件:

netstandard.dll, System.Xml.ReaderWriter.dll

來源:

XmlReader.cs

檢查目前的內容節點是否為終點標籤，並將讀取器推進至下一個節點。

public:
 virtual void ReadEndElement();

public virtual void ReadEndElement();

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

Public Overridable Sub ReadEndElement ()

例外狀況

XmlException

當前節點不是終端標籤，或若輸入串流中遇到錯誤 XML 則不存在。

InvalidOperationException

在先前非同步操作結束前，會呼叫一個 XmlReader 方法。 此時， InvalidOperationException 會拋出「非同步操作已進行中」的訊息。

範例

以下範例顯示每個元素的文字內容。

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

範例中使用了該 book3.xml 檔案。

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