XmlWriter.Close XmlWriter.Close XmlWriter.Close XmlWriter.Close Method

定義

派生クラスでオーバーライドされると、このストリームと基になるストリームを閉じます。When overridden in a derived class, closes this stream and the underlying stream.

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

例外

Close が呼び出された後に、追加出力を書き込む呼び出しが行われたか、この呼び出しの結果が無効な XML ドキュメントです。A call is made to write more output after Close has been called or the result of this call is an invalid XML document.

または-or-

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、XML ノードを書き込みます。The following example writes an XML node.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   
   // Create a writer to write XML to the console.
   XmlWriterSettings^ settings = gcnew XmlWriterSettings;
   settings->Indent = true;
   settings->OmitXmlDeclaration = true;
   XmlWriter^ writer = XmlWriter::Create( Console::Out, settings );
   
   // Write the book element.
   writer->WriteStartElement( L"book" );
   
   // Write the title element.
   writer->WriteStartElement( L"title" );
   writer->WriteString( L"Pride And Prejudice" );
   writer->WriteEndElement();
   
   // Write the close tag for the root element.
   writer->WriteEndElement();
   
   // Write the XML and close the writer.
   writer->Close();
   return 1;
}

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

public class Sample {
  
  public static void Main() {
  
     // Create a writer to write XML to the console.
     XmlWriterSettings settings = new XmlWriterSettings();
     settings.Indent = true;
     settings.OmitXmlDeclaration = true;
     XmlWriter writer = XmlWriter.Create(Console.Out, settings);

     // Write the book element.
     writer.WriteStartElement("book");

     // Write the title element.
     writer.WriteStartElement("title");
     writer.WriteString("Pride And Prejudice");
     writer.WriteEndElement();

     // Write the close tag for the root element.
     writer.WriteEndElement();
             
     // Write the XML and close the writer.
     writer.Close();

注釈

開いている要素または属性は、自動的に閉じられます。Any elements or attributes left open are automatically closed.

注意

メソッドを使用しXmlWriter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、を設定XmlDocumentするために XmlWriter を使用している場合、をXmlWriter閉じるまでは、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.
