The following code example demonstrates using this field to test the result of parsing an address.

PhysicalAddress^ StrictParseAddress( String^ address )
{
   PhysicalAddress^ newAddress = PhysicalAddress::Parse( address );
   if ( PhysicalAddress::None->Equals( newAddress ) )
      return nullptr;

   return newAddress;
}

public static PhysicalAddress? StrictParseAddress(string? address)
{
    PhysicalAddress newAddress = PhysicalAddress.Parse(address);
    if (PhysicalAddress.None.Equals(newAddress))
        return null;

    return newAddress;
}

Remarks

The Parse method returns None if you specify null address.
