How to send SMS using ASP.NET through HTTP (C#)

Hello Guys, This short ASP.NET code snippet is intended to provide you a brief review on how to add SMS functionality to your website. You will see, this is a very simple but smart solution. This ASP.NET application is able to send messages by using HTTP requests towards the SMS gateway that sends the SMSs to the destination telephone via a GSM modem or an IP SMS connection. Let’s take a quick look at the software requirements that are essentially needed for this solution. In order to send SMS messages from your ASP.NET application, you need a development platform, e.g Visual Studio, of course, .NET Framework 4.0, Internet Information Services (IIS) and an SMS gateway (I used Ozeki NG – http://www.ozekisms.com). You also need a GSM modem attached to your PC or an IP SMS connection to be able to send messages. Okay and now let’s use the code snippet! Copy the content of smssend.aspx and smssend.aspx.cs into the main directory of the IIS server - C:\Inetpub\wwwroot\ directory (). Configure the fixed data in the smssend.aspx.cs file (the IP address and port number of the SMS gateway, username, password). Launch your SMS gateway Server. Start a web browser and enter this URL: http://127.0.0.1/smssend.aspx - where 127.0.0.1 means that the smssend.aspx and smssend.aspx.cs files can be found on the same computer on which the browser has been opened). Fill in the required fields, and then click the Send button. It’s as easy as that! Happy coding! :)
