Hello, I'm working in a telecom company which requires a program for sending sms alerts how can I use the companies resources to send sms alerts using c# desktop application. Will be thankful if anyone can help.

Your first task is to research what is the interface that the company provides for sending SMS messages. It is likely that you will find that they have some kind of web application or REST API for sending the messages. Once you know the type of calls that you have to make, and presuming that they are some type of http calls, you can perform them from C# using one of the classes provided for this purpose such as WebClient or HttpWebRequest.
