public:
 System::Xml::XmlAttribute ^ Append(System::Xml::XmlAttribute ^ node);
public:
 virtual System::Xml::XmlAttribute ^ Append(System::Xml::XmlAttribute ^ node);
public System.Xml.XmlAttribute Append(System.Xml.XmlAttribute node);
public virtual System.Xml.XmlAttribute Append(System.Xml.XmlAttribute node);
member this.Append : System.Xml.XmlAttribute -> System.Xml.XmlAttribute
abstract member Append : System.Xml.XmlAttribute -> System.Xml.XmlAttribute
override this.Append : System.Xml.XmlAttribute -> System.Xml.XmlAttribute
Public Function Append (node As XmlAttribute) As XmlAttribute
Public Overridable Function Append (node As XmlAttribute) As XmlAttribute

參數

node
XmlAttribute

要插入的屬性。

傳回

XmlAttribute

該 XmlAttribute 書將附錄至收藏中。

例外狀況

ArgumentException

node 是根據一份與創建本收藏的文件不同的文件所創造的。

範例

以下範例為文件新增一個屬性。

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

public class Sample
{
  public static void Main(){

    XmlDocument doc = new XmlDocument();
    doc.LoadXml("<book ISBN='1-861001-57-5'>" +
                "<title>Pride And Prejudice</title>" +
                "</book>");

    //Create a new attribute.
    XmlAttribute newAttr = doc.CreateAttribute("genre");
    newAttr.Value = "novel";

    //Create an attribute collection and add the new attribute
    //to the collection.
    XmlAttributeCollection attrColl = doc.DocumentElement.Attributes;
    attrColl.Append(newAttr);

    Console.WriteLine("Display the modified XML...\r\n");
    Console.WriteLine(doc.OuterXml);
  }
}

Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()
  
    Dim doc as XmlDocument = new XmlDocument()
    doc.LoadXml("<book ISBN='1-861001-57-5'>" & _
                "<title>Pride And Prejudice</title>" & _
                "</book>")      

    'Create a new attribute.
    Dim newAttr as XmlAttribute = doc.CreateAttribute("genre")
    newAttr.Value = "novel"

    'Create an attribute collection and add the new attribute
    'to the collection.  
    Dim attrColl as XmlAttributeCollection = doc.DocumentElement.Attributes
    attrColl.Append(newAttr)

    Console.WriteLine("Display the modified XML...")
    Console.WriteLine(doc.OuterXml)

  end sub
end class

備註

如果集合中已有同名屬性，原始屬性會從集合中移除，並 node 被加到集合的末尾。

此方法是 Microsoft 對文件物件模型（DOM）的擴充。
