XmlWriter.Close Method

When overridden in a derived class, closes this stream and the underlying stream.

Namespace:  System.Xml
Assembly:  System.Xml (in System.Xml.dll)

public abstract void Close()

ExceptionCondition
InvalidOperationException

A call is made to write more output after Close has been called or the result of this call is an invalid XML document.

Any elements or attributes left open are automatically closed.

NoteNote:

When you use the XmlWriter methods to output XML, the elements and attributes will not be written until you call the Close method. 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.

The following example writes an XML node.

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();  

  }
}
#using <mscorlib.dll>
#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 = new XmlWriterSettings();
    settings->Indent = true;
    settings->OmitXmlDeclaration = true;
    XmlWriter* writer = XmlWriter::Create(Console::Out, settings);

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

    // Write the title element.
    writer->WriteStartElement(S"title");
    writer->WriteString(S"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;
}
