Exemplos
O exemplo a seguir exibe informações sobre as entidades declaradas no documento XML.The following example displays information about the entities declared in the XML document.
#using <System.Xml.dll>

Console::Write( " {0} ", ent->NodeType );
Console::Write( " {0} ", ent->Name );
Console::Write( " {0} ", ent->NotationName );
Console::Write( " {0} ", ent->PublicId );
