 abstract property int Count { int get(); };
public abstract int Count { get; }
member this.Count : int
Public MustOverride ReadOnly Property Count As Integer

屬性值

XmlNodeList 中的節點數目。The number of nodes in the XmlNodeList.

範例

下列範例會建立XmlDocument物件, 並GetElementsByTagName使用方法和產生XmlNodeList的來顯示所有書名。The following example creates a XmlDocument object and uses the GetElementsByTagName method and the resulting XmlNodeList to display all the book titles.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;

int main()
{
   XmlDocument^ doc = gcnew XmlDocument;
   doc->Load( "2books.xml" );
   
   // Get and display all the book titles.
   XmlElement^ root = doc->DocumentElement;
   XmlNodeList^ elemList = root->GetElementsByTagName( "title" );
   for ( int i = 0; i < elemList->Count; i++ )
   {
      Console::WriteLine( elemList[ i ]->InnerXml );
   }
}
using System;
using System.IO;
using System.Xml;

public class Sample
{
  public static void Main()
  {
     XmlDocument doc = new XmlDocument();
     doc.Load("2books.xml");
                         
     // Get and display all the book titles.
     XmlElement root = doc.DocumentElement;
     XmlNodeList elemList = root.GetElementsByTagName("title");
     for (int i=0; i < elemList.Count; i++)
     {   
        Console.WriteLine(elemList[i].InnerXml);
     } 
    
  }
}
Imports System
Imports System.IO
Imports System.Xml

public class Sample

  public shared sub Main()

    Dim doc as XmlDocument = new XmlDocument()
    doc.Load("2books.xml")
                         
     ' Get and display all the book titles.
     Dim root as XmlElement = doc.DocumentElement
     Dim elemList as XmlNodeList = root.GetElementsByTagName("title")
     Dim i as integer
     for i=0  to elemList.Count-1
        Console.WriteLine(elemList.ItemOf(i).InnerXml)
     next
    
  end sub
end class

此範例會使用2books.xml檔案做為輸入。The example uses the file 2books.xml as input.

<!--sample XML fragment-->
<bookstore>
  <book genre='novel' ISBN='10-861003-324'>
    <title>The Handmaid's Tale</title>
    <price>19.95</price>
  </book>
  <book genre='novel' ISBN='1-861001-57-5'>
    <title>Pride And Prejudice</title>
    <price>24.95</price>
  </book>
</bookstore>
