XmlWriter.WriteEndElement Method

Definition

Namespace:

System.Xml

Assembly:

System.Xml.ReaderWriter.dll

Source:

XmlWriter.cs

When overridden in a derived class, closes one element and pops the corresponding namespace scope.

public:
 abstract void WriteEndElement();

public abstract void WriteEndElement ();

abstract member WriteEndElement : unit -> unit

Public MustOverride Sub WriteEndElement ()

Exceptions

InvalidOperationException

This results in an invalid XML document.

-or-

An XmlWriter method was called before a previous asynchronous operation finished. In this case, InvalidOperationException is thrown with the message "An asynchronous operation is already in progress."

Examples

The following example uses the WriteEndElement and the WriteFullEndElement methods.

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;
     XmlWriter writer = XmlWriter.Create(Console.Out, settings);

     // Write the root element.
     writer.WriteStartElement("order");

     // Write an element with attributes.
     writer.WriteStartElement("item");
     writer.WriteAttributeString("date", "2/19/01");
     writer.WriteAttributeString("orderID", "136A5");

     // Write a full end element. Because this element has no
     // content, calling WriteEndElement would have written a
     // short end tag '/>'.
     writer.WriteFullEndElement();

     writer.WriteEndElement();

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

Option Explicit
Option Strict

Imports System.IO
Imports System.Xml

Public Class Sample
    
  Public Shared Sub Main()

     ' Create a writer to write XML to the console.
     Dim settings As XmlWriterSettings = new XmlWriterSettings()
     settings.Indent = true
     Dim writer As XmlWriter = XmlWriter.Create(Console.Out, settings)
        
     ' Write the root element.
     writer.WriteStartElement("order")
        
     ' Write an element with attributes.
     writer.WriteStartElement("item")
     writer.WriteAttributeString("date", "2/19/01")
     writer.WriteAttributeString("orderID", "136A5")
        
     ' Write a full end element. Because this element has no
     ' content, calling WriteEndElement would have written a
     ' short end tag '/>'.
     writer.WriteFullEndElement()
        
     writer.WriteEndElement()

     ' Write the XML to file and close the writer
     writer.Close()

    End Sub
End Class

Remarks

If the element contains no content, a short end tag "/>" is written; otherwise, a full end tag is written.

Note

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.

For the asynchronous version of this method, see WriteEndElementAsync.
