错误 CS0234 命名空间 'Telegram.Bot' 中不存在类型或命名空间名称 'SendTextMessageAsync'

Error CS0234 The type or namespace name 'SendTextMessageAsync' does not exist in the namespace 'Telegram.Bot'

我想在 c# 中的电报机器人中创建 InlineKeyBord 但我有这个错误:

CS0234 The type or namespace name 'SendTextMessageAsync' does not exist in the namespace 'Telegram.Bot'

var keyboard = new ReplyKeyboardMarkup(new [] {
  new [] // 1st row
  {
    new KeyboardButton("1"),
      new KeyboardButton("2"),
  },
  new [] // 2nd row
  {
    new KeyboardButton("3"),
      new KeyboardButton("4"),
  }
});

await Telegram.Bot.SendTextMessageAsync(message.Chat.Id, "Choose", replyMarkup: keyboard);

变化:

await Telegram.Bot.SendTextMessageAsync(message.Chat.Id, "Choose", replyMarkup: keyboard);

至:

// see https://mrroundrobin.github.io/telegram.bot/html/M_Telegram_Bot_TelegramBotClient__ctor.htm
var bot = new Telegram.Bot.TelegramBotClient(yourtokenhere); 
await bot.SendTextMessageAsync(message.Chat.Id, "Choose", replyMarkup: keyboard);
