有没有一种方法可以使我的程序将SMS发送到手机？

Question

So, I want to implement a function om my C# program, basically what I want to do is find a way to make the program identify the computer which its being accessed so if a not authorize computer try to access it the program will not open.

The way that I want to implement this is at the login screen the person that want to login will need to put their cellphone number and their password but if for some reason a person discover a functionary password and cellphone number and try to access the program with a computer that is not authorized to use the program the program will send a SMS to the functionary cellphone which they put and the person will need to put the aleatory code that will appear in the functionary cellphone, so basically I want to know how and if there is a way to do it, I am a noob with coding,but I appreciate any help. (sorry for any grammar errors or bad English)

Answer 1

As far as I'm aware, C# does not have a built in way to send SMS. But fear not, there is an online API you can use that is used by a good deal of big businesses. It's called Twilio , and they have a C# library you can access. The only issue that one might have with it is that it does cost money to use their services.

Hope this helps!

Answer 2

Does it need to be an SMS? If not, you can use the Time-Based One-Time Password Algorithm to have one-time codes. There are several .NET libraries available that provide this functionality.

Depending on the cell provider, you can have your c# application send an email to a phone # and the recipient will see that message in their text conversations. I've done this with AT&T sending an email to phonenumber@mms.att.net . Of course you will have to deal with different providers and how/if they accommodate this feature.
