XmlNodeList.Item(Int32) 方法
定义
检索给定索引处的节点。Retrieves a node at the given index.
public:
abstract System::Xml::XmlNode ^ Item(int index);
public abstract System.Xml.XmlNode Item (int index);
public abstract System.Xml.XmlNode? Item (int index);
abstract member Item : int -> System.Xml.XmlNode
Public MustOverride Function Item (index As Integer) As XmlNode
参数
- index
- Int32
节点列表中从零开始的索引。The zero-based index into the list of nodes.
返回
XmlNode 与集合中的指定索引.The XmlNode with the specified index in the collection. 如果 index 大于或等于列表中的节点数,则这返回 null。If index is greater than or equal to the number of nodes in the list, this returns null.
示例
下面的示例获取并显示中的第二个节点 XmlNodeList 。The following example gets and displays the second node in the 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.IO;
using System.Xml;
public class Sample {
public static void Main() {
XmlDocument doc = new 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);
}
}

Dim root as XmlElement = doc.DocumentElement
Dim nodeList as XmlNodeList = root.GetElementsByTagName("item")
Console.WriteLine(nodeList.Item(1).InnerXml)
end sub
