// Check whether the given XmlTextReader is readable.
if ( DiscoveryDocument::CanRead( myXmlTextReader ) == true )
      
// Read the given XmlTextReader.
myDiscoveryDocument = DiscoveryDocument::Read( myXmlTextReader );
else
      Console::WriteLine( "The supplied file is not readable" );

// Check whether the given XmlTextReader is readable.
if( DiscoveryDocument.CanRead( myXmlTextReader ) == true )
{
   // Read the given XmlTextReader.
   myDiscoveryDocument = DiscoveryDocument.Read( myXmlTextReader );
}
else
{
   Console.WriteLine( "The supplied file is not readable" );
}

' Check whether the given XmlTextReader is readable.
If DiscoveryDocument.CanRead(myXmlTextReader) = True Then
   ' Read the given XmlTextReader.
   myDiscoveryDocument = DiscoveryDocument.Read(myXmlTextReader)
Else
   Console.WriteLine("The supplied file is not readable")
End If
