利用其XmlNode屬性添加 並Name

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

參數

node
XmlNode

An XmlNode 要儲存在 XmlNamedNodeMap. 如果地圖中已有該名稱的節點，則會被新的節點取代。

傳回

XmlNode

若替 node 換了同名的現有節點，則回傳舊節點;否則， null 回傳。

例外狀況

ArgumentException

該 node 是由與XmlDocument創造 ;XmlNamedNodeMapXmlNamedNodeMap;或為唯讀的來源不同。

範例

以下範例使用 XmlAttributeCollection 類別（繼承自 XmlNamedNodeMap）來為集合添加屬性。

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

public class Sample
{
  public static void Main()
  {
     XmlDocument doc = new XmlDocument();
     doc.LoadXml("<book genre='novel' publicationdate='1997'> " +
                 "  <title>Pride And Prejudice</title>" +
                 "</book>");

     XmlAttributeCollection attrColl = doc.DocumentElement.Attributes;

     // Add a new attribute to the collection.
     XmlAttribute attr = doc.CreateAttribute("style");
     attr.Value = "hardcover";
     attrColl.SetNamedItem(attr);

     Console.WriteLine("Display the modified XML...");
     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 genre='novel' publicationdate='1997'> " & _
                "  <title>Pride And Prejudice</title>" & _
                "</book>")
                         
    Dim attrColl as XmlAttributeCollection = doc.DocumentElement.Attributes

    ' Add a new attribute to the collection.
    Dim attr as XmlAttribute = doc.CreateAttribute("style")
    attr.Value = "hardcover"
    attrColl.SetNamedItem(attr)

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