Namespace: System.Xml
Assembly: System.Xml (in system.xml.dll)

public string SystemId { get; }
/** @property */
public String get_SystemId ()

public function get SystemId () : String

Property Value

The system identifier on the notation. If there is no system identifier, a null reference (Nothing in Visual Basic) is returned.

The following example displays information on the notations declared in the XML document.

using System;
using System.IO;
using System.Xml;
 
public class Sample
{
  private const String filename = "doment.xml";
 
  public static void Main()
  {      
    XmlDocument doc = new XmlDocument();
    doc.Load(filename);

    Console.WriteLine("Display information on all notations...");     
    XmlNamedNodeMap nMap = doc.DocumentType.Notations;
    DisplayNotations(nMap);      
  }
 
  public static void DisplayNotations(XmlNamedNodeMap nMap)
  {   
     for (int i=0; i < nMap.Count; i++)
     {
        XmlNotation note = (XmlNotation) nMap.Item(i);
        Console.Write("{0} ", note.NodeType);
        Console.Write("{0} ", note.Name);
        Console.Write("{0} ", note.PublicId);
        Console.Write("{0} ", note.SystemId);
        Console.WriteLine();
    }
  }            
}

    public static void main(String[] args)
    {
        XmlDocument doc = new XmlDocument();
        doc.Load(fileName);

        Console.WriteLine("Display information on all notations...");
        XmlNamedNodeMap nMap = doc.get_DocumentType().get_Notations();
        DisplayNotations(nMap);
    } //main

    public static void DisplayNotations(XmlNamedNodeMap nMap)
    {
        for (int i = 0; i < nMap.get_Count(); i++) {
            XmlNotation note = (XmlNotation)nMap.Item(i);
            Console.Write("{0} ", note.get_NodeType());
            Console.Write("{0} ", note.get_Name());
            Console.Write("{0} ", note.get_PublicId());
            Console.Write("{0} ", note.get_SystemId());
            Console.WriteLine();
        }
    } //DisplayNotations
} //Sample

The example uses the file doment.xml as input.
