XmlDocument.IsReadOnly 屬性

public:
 virtual property bool IsReadOnly { bool get(); };

public override bool IsReadOnly { get; }

member this.IsReadOnly : bool

Public Overrides ReadOnly Property IsReadOnly As Boolean

屬性值

true 如果目前的節點是唯讀;否則 false。 XmlDocument 節點總是回傳 false。

範例

以下範例說明如何使用該 IsReadOnly 屬性。

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

Imports System.IO
Imports System.Xml

Public Class Sample
    
    Public Shared Sub Main()
        'Create the XmlDocument.
        Dim doc As 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 Then
            Console.WriteLine("Entity reference nodes are always read-only")
        End If 
    End Sub
End Class

備註

唯讀節點是指其屬性、屬性或子節點無法更改的節點。 你可以從樹狀結構中移除唯讀節點，然後插入到其他地方。

此屬性是 Microsoft 對文件物件模型（DOM）的擴充。
