Instantiation of a class to initialize fields...

Question

Hi

Given code like the following:-

URL info = new URL("http://www.domain.com:80/info/");

The string "http://www.domain.com:80/info/" I know would be stored in a field and then accessed via an auto property like so

var getHost = info.Host; // www.domain.com

But how would the property "Host" or more importantly the underlining field split the string. I assume the logic to do this would be in the property itself?

Regards
Steven

The most likely answer is that the Host property would contain code to split out the 'host'. A possible alternative would be for the constructor to split out all components of the url and save them in individual fields. However this would increase the memory footprint of the URL class considerably and so I think most library writers would prefer to split out these components as needed and take a small performance hit if they need to split them out more than once.

You've got it Steven :)

Oh I see so either the property OR the constructor could be responsible for the string split but if it was the constructor it would be an expensive way of doing it...
