C# Telegram Bot 内联模式发送按钮给用户

Question

I am trying to create an inline bot with: Telegram.Bot

I have added a method to the OnInlineQuery event. It gets called, But now I want to send a button back to the chat, which should be displayed above the keyboard. How do I accomplish this?

This is what I have so far:

BotClient.OnInlineQuery += BotOnInlineQuery;

protected async override void BotOnInlineQuery(object sender, InlineQueryEventArgs inlineQueryEventArgs)
{
    // Log info
    Log.Info("Inline called " + inlineQueryEventArgs.InlineQuery.From.FirstName);

    InlineQueryResult[] results =
    {
        new InlineQueryResultVenue()
    };


    await BotClient.SendTextMessageAsync(inlineQueryEventArgs.InlineQuery.Id, "test");
    
    // Answer with results
    await BotClient.AnswerInlineQueryAsync(
                    inlineQueryEventArgs.InlineQuery.Id,
                    results,
                    isPersonal: true,
                    cacheTime: 0);
}

Answer 1

You have some errors in your code:

1. You can't use SendTextMessageAsync with InlineQuery.Id
2. There is no constructor for InlineQueryResultVenue with no parameters
3. You can't override OnInlineQuery because it's not a method, It's an event!

Answer

To use Buttons with inline message use ReplyMarkup property with InlineKeyboardMarkup in InlineQueryResultBase .

And use chat links t.me, if I have username @BotFather use link: https://t.me/BotFather

So use InlineKeyboardButton.WithUrl("Go to chat", "https://t.me/my_chat_username") with your chat link.

Use this code:

private async void BotClient_OnInlineQuery(object sender, InlineQueryEventArgs e)
{
    // Some variables
    string link = "https://t.me/chat_username";
    // Your Button that you want
    InlineKeyboardButton button = InlineKeyboardButton.WithUrl("Go to chat", link);

    // Inline Results
    InlineQueryResultBase[] results = new[]  
    {
        new InlineQueryResultVenue(e.InlineQuery.Id, 30, 30, "Venue title", "address")
        //TODO: Add here any of InlineQueryResultVenue properties.
        {
            // HERE IS WHAT DO YOU WANT:
            // Keyboard:
            ReplyMarkup = new InlineKeyboardMarkup(button);
        }
    }
    
    // Answer with results:
    await BotClient.AnswerInlineQueryAsync(e.InlineQuery.Id,
                                           results,
                                           isPersonal: true
                                           cacheTime: 0);
}
