The following example reads an XML file and displays each of the nodes.

Visual Basic
reader.MoveToContent()
' Parse the file and display each of the nodes.
While reader.Read()
  Select Case reader.NodeType
    Case XmlNodeType.Element
      Console.Write("<{0}>", reader.Name)
    Case XmlNodeType.Text
      Console.Write(reader.Value)
    Case XmlNodeType.CDATA
      Console.Write("<![CDATA[{0}]]>", reader.Value)
    Case XmlNodeType.ProcessingInstruction
      Console.Write("<?{0} {1}?>", reader.Name, reader.Value)
    Case XmlNodeType.Comment
      Console.Write("<!--{0}-->", reader.Value)
    Case XmlNodeType.XmlDeclaration
      Console.Write("<?xml version='1.0'?>")
    Case XmlNodeType.Document
    Case XmlNodeType.DocumentType
      Console.Write("<!DOCTYPE {0} [{1}]", reader.Name, reader.Value)
    Case XmlNodeType.EntityReference
      Console.Write(reader.Name)
    Case XmlNodeType.EndElement
      Console.Write("</{0}>", reader.Name)
  End Select
End While

C#
reader.MoveToContent();
  // Parse the file and display each of the nodes.
  while (reader.Read()) {
    switch (reader.NodeType) {
      case XmlNodeType.Element:
          Console.Write("<{0}>", reader.Name);
          break;
      case XmlNodeType.Text:
          Console.Write(reader.Value);
          break;
       case XmlNodeType.CDATA:
           Console.Write("<![CDATA[{0}]]>", reader.Value);
           break;
       case XmlNodeType.ProcessingInstruction:
           Console.Write("<?{0} {1}?>", reader.Name, reader.Value);
           break;
       case XmlNodeType.Comment:
           Console.Write("<!--{0}-->", reader.Value);
           break;
       case XmlNodeType.XmlDeclaration:
           Console.Write("<?xml version='1.0'?>");
           break;
       case XmlNodeType.Document:
           break;
       case XmlNodeType.DocumentType:
           Console.Write("<!DOCTYPE {0} [{1}]", reader.Name, reader.Value);
           break;
       case XmlNodeType.EntityReference:
           Console.Write(reader.Name);
           break;
       case XmlNodeType.EndElement:
           Console.Write("</{0}>", reader.Name);
           break;
   } 
}

The sample uses the items.xml file.

<?xml version="1.0"?>
<!-- This is a sample XML document -->
<!DOCTYPE Items [<!ENTITY number "123">]>
<Items>
  <Item>Test with an entity: &number;</Item>
  <Item>Test with a child element <more/> stuff</Item>
  <Item>Test with a CDATA section <![CDATA[<456>]]> def</Item>
  <Item>Test with a char entity: &#65;</Item>
  <!-- Fourteen chars in this element.-->
  <Item>1234567890ABCD</Item>
</Items>
