In Console output, when finished -> write elapsed time

[timstarbuck]

Nice project! I added a counter and Interlocked.Increment/Decrement and a loop to wait for completion. Then I added an IOutput method to write a string (only implemented in Console output).

Seems you could also raise an event so the driving program knows its finished.

Let me know what you think!

How about this way of doing it, do you see any differences?

I guess it depends on what we are trying to actually time :)

Showing the elapsed time of each request seems beneficial. I took a different meaning. I took "when finished" to mean when the site crawl has completed crawling all the links.

Hey, and thanks for contributing to my repository here 😄
I have tested your code and it works.
It may be because I'm not used to this type of code, but I get a feeling that this code is a bit "hacky"

while (counter > 0) { Thread.Sleep(100); } 

And the problem is that I don't really know (right now) how to do it in another way, but I had something like this in mind: http://stackoverflow.com/a/25010220. I dont think we can use this here, because then we would need to have all the urls to crawl at start.
Without any research I have also thought about solving this by implementing some sort of queue that you would add urls to, and in the same time the program would get urls from the queue and crawl. What do you think?

Ha, yes. I felt it was a bit "hacky" as well, but as you mentioned, it works ;). Its a bit of a chicken and egg problem. You don't know how many links there are to crawl until they've all been crawled. I'll ponder your notes some and see if I can think of another way.
