XmlWriter.WriteEndDocument メソッド

定義

派生クラスでオーバーライドされると、開いている任意の要素または属性を閉じ、ライターを Start 状態に戻します。When overridden in a derived class, closes any open elements or attributes and puts the writer back in the Start state.

public:
 abstract void WriteEndDocument();
public abstract void WriteEndDocument ();
abstract member WriteEndDocument : unit -> unit
Public MustOverride Sub WriteEndDocument ()

例外

XML ドキュメントが無効です。The XML document is invalid.

先行の非同期操作が完了する前に、XmlWriter メソッドが呼び出されました。An XmlWriter method was called before a previous asynchronous operation finished. この場合、「非同期操作が既に実行されています」というメッセージと共に InvalidOperationException がスローされます。In this case, InvalidOperationException is thrown with the message "An asynchronous operation is already in progress."

次の例では、書籍を表す XML ファイルを書き込みます。The following example writes an XML file representing a book.

using System;
using System.IO;
using System.Xml;

public class Sample {

  private const string filename = "sampledata.xml";

  public static void Main() {
  
     XmlWriterSettings settings = new XmlWriterSettings();
     settings.Indent = true;
     XmlWriter writer = XmlWriter.Create(filename, settings);

     // Write the Processing Instruction node.
     String PItext="type=\"text/xsl\" href=\"book.xsl\"";
     writer.WriteProcessingInstruction("xml-stylesheet", PItext);

     // Write the DocumentType node.
     writer.WriteDocType("book", null , null, "<!ENTITY h \"hardcover\">");
        
     // Write a Comment node.
     writer.WriteComment("sample XML");
    
     // Write the root element.
     writer.WriteStartElement("book");

     // Write the genre attribute.
     writer.WriteAttributeString("genre", "novel");
    
     // Write the ISBN attribute.
     writer.WriteAttributeString("ISBN", "1-8630-014");

     // Write the title.
     writer.WriteElementString("title", "The Handmaid's Tale");
              
     // Write the style element.
     writer.WriteStartElement("style");
     writer.WriteEntityRef("h");
     writer.WriteEndElement(); 

     // Write the price.
     writer.WriteElementString("price", "19.95");

     // Write CDATA.
     writer.WriteCData("Prices 15% off!!");

     // Write the close tag for the root element.
     writer.WriteEndElement();
             
     writer.WriteEndDocument();

     // Write the XML to file and close the writer.
     writer.Flush();
     writer.Close();  
  }

注意

XmlWriter メソッドを使用して XML を出力する場合、Close メソッドを呼び出すまで、要素と属性は書き込まれません。When you use the XmlWriter methods to output XML, the elements and attributes will not be written until you call the Close method. たとえば、XmlWriter を使用して XmlDocumentを設定している場合、XmlWriterを閉じるまで、ターゲットドキュメント内の記述された要素と属性を確認することはできません。For example, if you are using the XmlWriter to populate an XmlDocument, until you close the XmlWriter, you will not be able to observe the written elements and attributes in the target document.

このメソッドの非同期バージョンについては、「WriteEndDocumentAsync」を参照してください。For the asynchronous version of this method, see WriteEndDocumentAsync.
