Tips & Tricks:

Please add some!

I tried this code and found it doesn't work. I got an empty class after calling. How I solved:

1) making class a struct

2) adding MarshalAs attibute to string members in order to set the maximum length of string

Since I've done it i got a filled structure with detailed information about WinSock. Not an empty one.
