CreateComment Method

XmlDocument.CreateComment Method

Creates an XmlComment containing the specified data.

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

public virtual XmlComment CreateComment(
	string data
)

Parameters

data
Type: System.String
The content of the new XmlComment.

Return Value

Type: System.Xml.XmlComment
The new XmlComment.

Although this method creates the new object in the context of the document, it does not automatically add the new object to the document tree. To add the new object, you must explicitly call one of the node insert methods.

According to the W3C Extensible Markup Language (XML) 1.0 recommendation (www.w3.org/TR/1998/REC-xml-19980210), Comment nodes are only allowed within Document, Element and EntityReference nodes, when the EntityReference node is not a child of an Attribute node.

The following example creates a comment and adds it to an XML document.


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

public class Sample
{
  public static void Main()
  {
    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<book genre='novel' ISBN='1-861001-57-5'>" +
                "<title>Pride And Prejudice</title>" +
                "</book>");

    //Create a comment.
    XmlComment newComment;
    newComment = doc.CreateComment("Sample XML document");

    //Add the new node to the document.
    XmlElement root = doc.DocumentElement;
    doc.InsertBefore(newComment, root);

    Console.WriteLine("Display the modified XML...");        
    doc.Save(Console.Out);

  }
}
