How do I add multiple locations on Google Maps via Telegram Bot? - google-maps-api-3

Question

I want to send multiple locations pinned on a single map into telegram-bot, by using send location function. is there a way to send multiple locations to telegram bot? I try and just can send one location to telegram bot.

Answer 1

As I understood you want to send multiple locations to the user so you don't want to put numbers in the SendLocation method. If the locations that need to be sent are some fixed locations you can save them in an array or in a DB and use a loop to send them.
But if they're not fixed you have to send them to the bot first and then force the bot to send to a user or anywhere else.(channel or group) The code below may help you:
//Send the location like: latitude=xxx&longtitude=yyy;
if(update.Message.Text.Contains("latitude") && update.Message.Text.Contains("longtitude"))
{
string latitude = text.Split('&').First();
string longtitude = text.Split('&').Last();
//splites the input text into two parts first part is latitude=xxx and second or last part is longtitude=yyy. because the string is splited based on & sign
float latitue_num = float.Parse(latitude.Split('=').Last());
float longtitude_num = float.Parse(longtitude.Split('=').Last());
//does the same action for "latitude=xxx" and "longtitude=yyy" after that the number xxx is stored in latitude_num and yyy is stored in longtitude_num
var req = new SendLocation(update.Message.Chat.Id, latitue_num, longtitude_num);
await bot.MakeRequestAsync(req);
}
Of course if the number of locations is too big, it's better to use a database and send them to bot from the DB.
And if you want to send the locations from a user to the bot(not from bot to a user) you can use:
if(update.Message.Location != null)
{
.
.
.
//here you can do whatever you want every time bot receives a location. no matter how many locations are sent to the bot the bot will receive them one by one and do the action(s) listed in this method.
}
I hope these will help you, your question was not clear therefore I explained this way.

You Can't.
This method Just send point on the map.
