which classes are used in asp.net

Question

i am currently learning desktop/ console app programming with c#

i am curious to know when you write asp.net web pages do you still use the same classes
that you use in writing desktop apps

eg using system
  using threading
etc

or is it that when you write asp.net web pages you are only allowed to use a certain category of classes.

thnx

Answer 1

Use:

string[] items = fileName.Split('_');

items[0] will be the portion to the first _ and then items[1] will be the portion from the first _ to the second _.

These will exclude the underscores themselves.

Answer 2

You could deal with that situation (or even two hyphen delimiters) by replacing this line:

   string[] items = fileName.Split('_');

with this:

   string[] items = fileName.Split(new char[]{'_', '-'});
