how to send message via telegram Bot in c#?

Question

I'm new on telegram Bot programmer and want to write a simple console application to send a message on telegram.

After some research I developed this codes with no error but it doesn't works and does not send my message. When i traced my code i found that status on result object is "waiting for activation" , what;s this mean?

I registered my bot and have a API access Token and used it on this codes.

Please guide me :)

static void Main(string[] args)
    {

        Task<Message> result;
        result= DoSomethingAsync();

        Console.WriteLine();
    }
    static async Task<Message> DoSomethingAsync()
    {
        var Bot = new Telegram.Bot.Api("my API access Token");
       return await Bot.SendTextMessage("@blablavla", "test message");
    }

You'd need to use result = await DoSomethingAsync() (as I indicated in my now deleted answer), but that's not possible in the Main() method. See stackoverflow.com/questions/9208921/… — user247702

You can build you own async main-method like this:

static void Main(string[] args)
{
    MainAsync(args).Wait();

    Console.ReadKey();
}

static async Task MainAsync(string[] args)
{
    Message result;
    Console.WriteLine("Sending Message...");
    result = await DoSomethingAsync();
    Console.WriteLine("Message sent...");
    Console.WrtieLine(result);
}

static async Task<Message> DoSomethingAsync()
    {
        var Bot = new Telegram.Bot.Api("my API access Token");
        return Bot.SendTextMessage("@blablavla", "test message"); // It's your last call to an async function in an async function, no need to await it here.
    }

this should do what you want. But please note that it is untested!

first create your bot

Telegram.Bot.Api bot = new Telegram.Bot.Api("my API access Token");

and then write a code like this in any method that you want. when this method runs it whould send your message to the user after each message to be sent. and will notify u in the console.

int offset = 0;
            while (true)
            {
                Telegram.Bot.Types.Update[] updates = bot.GetUpdates(offset).Result;
                foreach (var update in updates)
                {
                    offset = update.Id + 1;
                    if (update.Message == null)
                        continue;

                    Console.WriteLine("Sending Message...");
                    bot.SendTextMessage(update.Message.Chat.Id, "your text");
                    Console.WriteLine("Message sent...");
                    update.Message.Text);
                }
            }

try it
