检索给定索引处的节点。
public:
abstract System::Xml::XmlNode ^ Item(int index);C#
public abstract System.Xml.XmlNode Item (int index);C#
public abstract System.Xml.XmlNode? Item (int index);abstract member Item : int -> System.Xml.XmlNodePublic MustOverride Function Item (index As Integer) As XmlNode- index
- Int32
节点列表中从零开始的索引。
XmlNode 与集合中的指定索引. 如果 index 大于或等于列表中的节点数，则这返回 null。
以下示例获取并显示第二个节点。XmlNodeList
#using <System.Xml.dll>
using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
XmlDocument^ doc = gcnew XmlDocument;
doc->LoadXml( "<items>"
" <item>First item</item>"
" <item>Second item</item>"
"</items>" );
//Get and display the last item node.
XmlElement^ root = doc->DocumentElement;
XmlNodeList^ nodeList = root->GetElementsByTagName( "item" );
Console::WriteLine( nodeList->Item( 1 )->InnerXml );
}

using System;

using System.Xml;
public class Sample {
public static void Main() {
XmlDocument doc = new XmlDocument();
doc.LoadXml("<items>" +

"</items>");
//Get and display the last item node.
XmlElement root = doc.DocumentElement;
XmlNodeList nodeList = root.GetElementsByTagName("item");
Console.WriteLine(nodeList.Item(1).InnerXml);
}
