如何在 c# 中查找电报机器人发送的消息是否已正确发送到通道？

Question

I have designed a telegram bot (c# winforms project) which sends messages to a telegram channel. I want to find if my sending message in the last try has been sent to the channel correctly or not? Is there a way to find that?

I am using the following code in order to send my message:

string chatId = "@MyChannel";
string testMessage = "Hello Channel";
bot.SendTextMessageAsync(chatId, testMessage, ParseMode.Html);

You can use it by defining message, because SendTextMessageAsync method returns message on success (see Telegram API docs ), do like this:

Message msg = await bot.SendTextMessageAsync(chatId, testMessage, ParseMode.Html);

if (msg is null)
{
    // Message didn't arrive!
}
else
{
    // Message Arrived successfully!
}
