XmlDocument.IsReadOnly Property

Definition

Gets a value indicating whether the current node is read-only.

public override bool IsReadOnly { get; }

Property Value

true if the current node is read-only; otherwise false. XmlDocument nodes always return false.

Examples

The following example shows how to use the IsReadOnly property.

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

public class Sample
{
  public static void Main()
  {
    //Create the XmlDocument.
    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<!DOCTYPE book [<!ENTITY h 'hardcover'>]>" +
                "<book genre='novel' ISBN='1-861001-57-5'>" +
                "<title>Pride And Prejudice</title>" +
                "<style>&h;</style>" +
                "</book>");

    //Determine whether the node is read-only.
    if (doc.DocumentElement.LastChild.FirstChild.IsReadOnly)
       Console.WriteLine("Entity reference nodes are always read-only");
  }
}

Remarks

A read-only node is one whose properties, attributes, or children cannot be changed. You can remove a read-only node from the tree and insert it somewhere else.

This property is a Microsoft extension to the Document Object Model (DOM).
