[c#] IMDB Info Grabber (Full program)

[jayfella]

Ok.

Here is a handy little application - fully working - that obtains information from IMDB.com.

Fundamentally you can go much further, but im releasing the code thus far so users can learn from the code and how its used.

useage: enter a movie URL into the textbox and click search.
Example: http://www.imdb.com/title/tt0892318/
