C# Example of data managment, ArrayList, List
Language: C#
This code doesn’t do anything usefull, it is only an example how can be used some of function as ArrayList, List<>, class and some other, as i has start programming in C# i write some Irc client, and this the code i will be using for managing users and channels.
So I write this code becouse i wan’t see and show you how can you write and irc chat client mybe will be usefull to you, for me is it. 
Programski jezik: C#
No tuki je en primer kako lahko shranjujemo uporabnike kanale in sporočila, če programiramo irc client, celotno stvar se verjetno, da sprogramirat boljše in slabše, in še na 100 drugih načino. No mogoče kdo kaj uporabnega najde v tej kodi.
