[C#] Switch Statement with RegEx?

[G_G]

I'm trying to replicate RMX-OS here. That way I don't have to have a crap ton of lines. Basically trying to do this in C#.

	def check_connection
		case @message
		when /\ALIN(.+)\t(.+)/ # login request
			result = @action.try_login($1, $2)
			# if login was successful
			if result == RMXOS::RESULT_SUCCESS
				# send user data
				self.send("UID#{@player.user_id}")
				self.send("USR#{@player.username}")
				self.send("UGR#{@player.usergroup}")
				self.send("BUD#{@player.get_buddies_list}")
				# send guild data
				if @player.guildname != ''
					self.send("GIN#{@player.guildname}\t#{@player.guildleader}\t#{@player.get_guildmembers_list}")
				end
			end
			self.send("LIN#{result}")
			return true
		when /\AREG(.+)\t(.+)/ # register request
			result = @action.try_register($1, $2)
			# if registering was successful
			if result == RMXOS::RESULT_SUCCESS
				# log in as well
				@action.try_login($1, $2)
				# send user data
				self.send("UID#{@player.user_id}")
				self.send("USR#{@player.username}")
				self.send("UGR#{@player.usergroup}")
				self.send("BUD#{@player.get_buddies_list}")
				# send guild data
				if @player.guildname != ''
					self.send("GIN#{@player.guildname}\t#{@player.guildleader}\t#{@player.get_guildmembers_list}")
				end
			end
			self.send("REG#{result}")
			return true
		when /\ACON(.+)/ # connection request
			version = $1.to_f
			# get all properly connected clients
			clients = $clients.find_all {|client| client.player.user_id != 0}
			# version not high enough
			if version < RMXOS_VERSION
				result = RMXOS::RESULT_FAIL
			# server is full
			elsif (clients - [self]).size >= MAXIMUM_CONNECTIONS
				result = RMXOS::RESULT_DENIED
			else
				result = RMXOS::RESULT_SUCCESS
			end
			self.send("CON#{result}\t#{RMXOS_VERSION}")
			return true
		end
		return false
	end

Having a little trouble figuring out how thats going to work exactly.

tbh I've never used regexp in C#, I just use string.split

lulz thats what I'd usually do. xD I really don't think thats the case here though. =\ Meh I'll keep looking through google.

I used Regexp extensively in my rmxos cfg app take a look at the source and look at the part that reads the config file.

I'm trying to do it without having all of these extra match variables and if branches. It looks like thats what I'm going to have to do though.

ya that's the only way it works. kinda sad that it isn't a smooth and easy as ruby. even python doesn't do RegEx as well as ruby.

This is probably the closest I'll get to keeping minimal code.

            string pattern = "\\AUID(.+)";
            if (Regex.Match(msg, pattern).Success)
                client.user_id = Convert.ToInt32(Regex.Replace(msg, pattern, "$1"));
            pattern = "\\AUSR(.+)";
            if (Regex.Match(msg, pattern).Success)
                client.username = Regex.Replace(msg, pattern, "$1");
            pattern = "\\AUGR(.+)";
            if (Regex.Match(msg, pattern).Success)
                client.usergroup = Convert.ToInt32(Regex.Replace(msg, pattern, "$1"));

EDIT: On a side note, this program is gonna be awesome. A whole different way to boss your server around.

I used regex for text based formats such as a localization file format that we use at Cateia.
