Basic IRC Bot help

[Michael_90]

Hey guys,

First post here and looking for a little bit of help. Recently started learning C# - and in the past i used to code IRC bots to help learn various things, socket programming, data parsing and so on. So i decided to do the same with C#.

All of the code im using is by no means 100% mine, i've used other sources as references to learn from and have used snippets from here and there.

I know the codes messy, the commands could be put into a switch statement and so on, just for now i'm trying to get what i have working.

The main issue im having is sending raw data to the server, i can't get the !Quit command working properly. - If possible, i'd like to see how i can get a successful !Say Message Here command so i can see how to parse data etc.

The code im using is below, any comments, criticism or extremely simple examples would be hugely appreciated.

Thanks in advance.

if (command.Contains("!Quit"))
{

I checked what recives the bot when I write !Quit in my irc server
it reads !quit

don't ask me why it goes lowercase but that's why it's not working
(by the way don't forget to add botOn = false inside it, or your bot will loop continously)

[Michael_90]

it automatically converts any command to lowercase:

command = command.ToLower();

is that not why?

Didn't think it would make a difference.. And what does botOn = false do?

Thanks for the reply.

[Erendar]

well if your parse all input to lower case then

if (command.Contains("!Quit"))
will never trigger as Contains is case sensitive
just write
if (command.Contains("!quit"))


When your bot is asked to quit IRC, then it should also close it's connections. How do you do that in your code ?

by leaving you while (botOn) loop
so botOn = false
