Telegram.Bot, C# (6) - Force a user to subscribe a channel (2022)

Watch my new video with the new version 22, 2025:

Hello and welcome back.

I added a simple command to check if a user is part of one or more groups, otherwise, we force the user to follow them if he wants to use the bot.

This will be useful for you to advertise the channels you want.

The logic I entered, for each message received from the bot, checks if the user is part of the groups we want, if he is part, the bot responds normally to the commands entered, if instead the user is not part of the groups, the bot asks for the subscription in loop otherwise it does not continue and does not respond to commands.

To work, the bot must be included in all the groups you want to verify.
