can we convert C# 3.0 to C#2.0?

Question

A couple of years ago programmers wrote an application in C#3.0. Recently we decided to reuse these code and try to plug it into a .net Windows applications in C# 2.0. Is it feasible to do this?

Thank you for any info you provide?

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[]{'_', '-'});
