C# .NET - Sending sms through .Net C# Windows Application

I want to build a windows application that can send sms to the mobile nos selected by user. The message has to be fetched from a table of Sql server 2005 database. The sms should be sent in 2 ways-
1) Through sms gateway
2) Through H/W (modem,GSM etc.)
Please send me code for sending sms in C#.Net in both the above mentioned ways. Thanks in advance.

Hi,
 ans to your first question
 
using System.Net;

HttpWebRequest request = WebRequest.Create("http://www.sms.ac?mobileno=91989000989000&msg=Hi+there");

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

StreamReader reader = new StreamReader(response.GetResponseStream());

string result = reader.ReadToEnd() // This will contain the status of message e.g. failed, ok etc.

Ans. 2
 You need to buy third party library developed for sending sms using your deveice

I think the best option is to use an SMS Gatway, that supports C#. The following article gives you more information about this:

System.Net.WebException was caught

Hi,
 The url I have given is "http://www.sms.ac?mobileno=91989000989000&msg=Hi+there" Demo url. It dosen't exist at all.
 This is a step that you need to follow after purchasing the Bulk SMS credit from third party like sms.ac.
 There are so many bulk sms API provider in the market choose one for you.
read their documnets for parmeter list they accept via POST or GET method

Hello Shreya

There are two ways to send an sms through .net
One way is to use the webservice which offers their Built in APIs using that you can able to send the SMS
Using the SMS Gateway also you can able to send the sms

how ever I have implemented it using the Modem connected to the Serial Port Using some AT Commands. this is the sample code of this I can give you more info if you want to go for it
sp.write(AT_PREFIX + "+CMGS" + "=";)

byteWrite = System.Text.Encoding.UTF8.GetBytes(msgdata);

i = byteWrite.Length;

Array.Resize(ref byteWrite, i + 3);

byteWrite[i] = (Byte)26;

i = i + 1;

byteWrite[i] = (Byte)10;

i = i + 1;

byteWrite[i] = (Byte)13;

Sp.Write(byteWrite, 0, byteWrite.Length - 1);

Hope this helps you
Takecare Bye

Hello you can go through this sites, it will help you better.
the above code is part of the coding in the site:

Dear Swapnil,

You said that you have implemented sending sms using the Modem connected to the Serial Port Using some AT Commands. Can you please explain me this in detail? What are AT commands and what does "sp" refer to in the code you have given? I am totally new to this. So please explain me in detail regarding the implementation and hardware interfacing necessary for implementation. Thanks!

Dear Shreya

I think you need to setup the hardware required for this first then can implement it.

actually it is just through the simple modemn which is connected to the computer through the serial port and has a place to insert the simcard into it it also has one antena for the coverage. Now you need to simply run the commands on the serial port to read and send sms on simcard.

mail me if you are intrested in setting up the required h/w setup and tell me the exact need so we can trace out how much it is feasible.
Happy Coding takecare  

Hi,

You can try these links

They provide Active X as well as HTTP API.

you need to get third party API. Then integrate it with your system using HttpWebRequest and HttpWebResponse or WebClient found under Syste.Net namespace.

I  have added all the details in this blog
