Telegram.Bot.Framework

This Framework is an early beta which will be developed the next few weeks / months. It's based on Telegram.Bot.

The goal is to achieve a simple and lightweight framework to build chat bots with reusable code.

ICommand

An ICommand is a simple command without parameters. Each class wich derives from ICommand can be called by different commands through the CommandAttribute.

Example 1 - No parameters

[Command("/start")] //The CommandAttribute defines the command to call the Command from Telegram-Chat
[Command("/start2")] //You can define several commands
class StartCommand : ICommand
{
    public async Task<bool> CanInvoke(ITelegramBotClient client, Update update, object args) //CanInvoke gives the ability to check whether the command can be actually called
    {
        return true;
    }

    public async Task<bool> Invoke(ITelegramBotClient client, Update update, object args)
    {
        return await data.Client.SendTextMessageAsync(data.Update.Message.Chat.Id, "Hello World!");
        return true;
    }
}

Example 2 - With parameters

//You can simply define the paramater with {} and define the parameter container
//If you send the message "/start 5", the bot will answer with "Hello World 5!"
[Command("/start {id}", ArgumentType = typeof(StartCommandParameter))]
//The default command can be in the same class
//If you send the message "/start", the bot will answer with "Hello World!"
[Command("/start")]
class StartCommand : ICommand, ICommand<StartCommandParameter>
{
    public async Task<bool> CanInvoke(ITelegramBotClient client, Update update, object args) //CanInvoke gives the ability to check whether the command can be actually called
    {
        return true;
    }

    public async Task<bool> Invoke(ITelegramBotClient client, Update update, object args)
    {
        await data.Client.SendTextMessageAsync(data.Update.Message.Chat.Id, "Hello World!");
        return true;
    }
    public async Task<bool> CanInvoke(ITelegramBotClient client, Update update, StartCommandParameter args)
    {
        return true;
    }

    public async Task<bool> Invoke(ITelegramBotClient client, Update update, StartCommandParameter args) //If the id were an integer, args.Id is set
    {
        await data.Client.SendTextMessageAsync(data.Update.Message.Chat.Id, "Hello World "+ args.Id +"!");
        return true;
    }
}
class StartCommandParameter
{
    public int Id { get; set; }
}

##Initialize and start using the bot

    static void Main(string[] args)
    {
        var client = new Telegram.Bot.TelegramBotClient("your_token"); //initialize the client
        _helper = new Telegram.Bot.Framework.TelegramBotClientHelper(client); //inititalize the client helper
        _helper.CommandManager.RegisterCommand(new StartCommand()); //register the StartCommand from Example 1 or 2
        client.StartReceiving(); //Start receiving commands

        while (true)
            Console.ReadKey();
    }
