定義

現在のノードが読み取り専用かどうかを示す値を取得します。Gets a value indicating whether the current node is read-only.

public:
 virtual property bool IsReadOnly { bool get(); };
public override bool IsReadOnly { get; }
member this.IsReadOnly : bool
Public Overrides ReadOnly Property IsReadOnly As Boolean

プロパティ値

現在のノードが読み取り専用の場合は true。それ以外の場合は falsetrue if the current node is read-only; otherwise false. XmlDocument ノードは常に false を返します。XmlDocument nodes always return false.

IsReadOnly プロパティを使用する方法を次の例に示します。The following example shows how to use the IsReadOnly property.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   
   //Create the XmlDocument.
   XmlDocument^ doc = gcnew 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>" );
   
   //Check if the node is read-only.
   if ( doc->DocumentElement->LastChild->FirstChild->IsReadOnly )
      Console::WriteLine( "Entity reference nodes are always read-only" );
}

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");

  }
}
Option Explicit
Option Strict

注釈

読み取り専用ノードとは、プロパティ、属性、または子を変更できないノードのことです。A read-only node is one whose properties, attributes, or children cannot be changed. ツリーから読み取り専用ノードを削除し、別の場所に挿入することができます。You can remove a read-only node from the tree and insert it somewhere else.

このプロパティは、ドキュメント オブジェクト モデル (DOM) の Microsoft 拡張機能です。This property is a Microsoft extension to the Document Object Model (DOM).
