Definition

Namespace:

System.Xml

Assembly:

System.Xml.ReaderWriter.dll

Source:

XmlTextReader.cs

Gets the base URI of the current node.

public:
 virtual property System::String ^ BaseURI { System::String ^ get(); };

public override string BaseURI { get; }

member this.BaseURI : string

Public Overrides ReadOnly Property BaseURI As String

Property Value

String

Examples

The following example displays the base URI for each of the nodes.

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{
   XmlTextReader^ reader = nullptr;
   try
   {
      
      //Load the reader with the XML file.
      reader = gcnew XmlTextReader( "http://localhost/baseuri.xml" );
      
      //Parse the file and display the base URI for each node.
      while ( reader->Read() )
      {
         Console::WriteLine( "({0}) {1}", reader->NodeType, reader->BaseURI );
      }
   }
   finally
   {
      if ( reader != nullptr )
            reader->Close();
   }

}

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

public class Sample
{
  public static void Main()
  {
    XmlTextReader reader = null;

    try
    {
        //Load the reader with the XML file.
        reader = new XmlTextReader("http://localhost/baseuri.xml");

        //Parse the file and display the base URI for each node.
        while (reader.Read())
        {
            Console.WriteLine("({0}) {1}", reader.NodeType, reader.BaseURI);
         }
     }

     finally
     {
       if (reader!=null)
         reader.Close();
     }
  }
} // End class

Public Class Sample
   
   Public Shared Sub Main()
      Dim reader As XmlTextReader = Nothing
      
      Try
         'Load the reader with the XML file.
         reader = New XmlTextReader("http://localhost/baseuri.xml")
         
         'Parse the file and display the base URI for each node.
         While reader.Read()
            Console.WriteLine("({0}) {1}", reader.NodeType, reader.BaseURI)
         End While
      
      Finally
         If Not (reader Is Nothing) Then
            reader.Close()
         End If
      End Try
   End Sub
End Class

The example uses the file, baseuri.xml, as input.

Remarks

Note

Starting with the .NET Framework 2.0, we recommend that you create XmlReader instances by using the XmlReader.Create method to take advantage of new functionality.

A networked XML document is comprised of chunks of data aggregated using various W3C standard inclusion mechanisms and therefore contains nodes that come from different places. DTD entities are an example of this, but this is not limited to DTDs. The base URI tells you where these nodes came from. If there is no base URI for the nodes being returned (for example, they were parsed from an in-memory string), String.Empty is returned.
