Sending SMS from ASP.NET C# 4.0 application to Mobile using XML API

December 19, 2011 15 Comments


Sending & Receiving SMS from ASP.NET application is nowadays integrate parts of enterprise web application specially in the domains of Healthcare, Hospitality, Insurance , Banking sectors where 24X7  available approach with customers are mandatory.

  • In those respect , I have used a code in C# ASP.NET 4.0 using XML API (Purchased from Value-First SMS Provider) to send SMS from our web application to our clients randomly.
  • So, first develop the GUI for sending SMS. So the following code in .aspx:

<%@Page Language=”C#”AutoEventWireup=”true”CodeBehind=”SMS.aspx.cs”Inherits=”SMSTest.SMS” %>


<!DOCTYPE htmlPUBLIC“-//W3C//DTD XHTML 1.0 Transitional//EN”“http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”&gt;

<html xmlns=”http://www.w3.org/1999/xhtml”&gt;

<head runat=”server”>

<title></title>

</head>

<body style=”height: 313px”>

<form id=”form1″runat=”server”>

<div>

<h1> Sending SMS Application </h1>

</div>

<p>

<asp:LabelID=”lblTo”runat=”server”Text=”To:-“></asp:Label>

</p>

<asp:TextBoxID=”txtTo”runat=”server”></asp:TextBox>

<p>

<asp:LabelID=”lblFrom”runat=”server”Text=”From:-“></asp:Label>

</p>

<asp:TextBoxID=”txtFrom”runat=”server”Width=”128px”></asp:TextBox>

<p>

<asp:LabelID=”lblBody”runat=”server”Text=”SMS Message:-“></asp:Label>

</p>

<p>

<asp:TextBoxID=”txtBody”  TextMode=”MultiLine”runat=”server”></asp:TextBox>

</p>

<asp:ButtonID=”btnSend”runat=”server”onclick=”btnSend_Click”Text=”Send”/>

<p>

<asp:Label ID=”lblResult”runat=”server”Text=” “></asp:Label>

</p>

</form>

</body>

</html>

  • Now , check in Code-behind.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

using System.IO;

using System.Net;

using System.Text;


namespace SMSTest

{

public partial class SMS : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

}

protected void btnSend_Click(object sender, EventArgs e)

{

System.Net.WebClient webClient = new System.Net.WebClient();

string postData = “usr=yourapiusername&pwd=yourapipwd&from= “ + txtFrom.Text + “&to=” + txtTo.Text +“&type=text” + txtBody.Text;

webClient.Headers.Add(“Content-Type”,“application/x-www-form-urlencoded”);

lblResult.Text = webClient.UploadString(“http://api.myvaluefirst.com/psms/servlet/psms.Eservice2?data=&lt;?xml%20version=\”1.0\”%20encoding=\”ISO-8859-1\”?><!DOCTYPE%20MESSAGE%20SYSTEM%20\”http://127.0.0.1/psms/dtd/message.dtd\”%20><MESSAGE><USER%20USERNAME=\”Your SMS API Username” + “\”%20PASSWORD=\”Your SMS API Password” + “\”/><SMS%20UDH=\”0\”%20CODING=\”1\”%20TEXT=\”” + txtBody.Text + “\”%20PROPERTY=\”0\”%20ID=\”1\”><ADDRESS%20FROM=\”919903013543\”%20TO=\”” + txtTo.Text + “\”%20SEQ=\”1\”%20TAG=\”some%20clientside%20random%20data\”%20/></SMS></MESSAGE>&action=send”, postData);

}

}

}

  • Next , Check the output for sending SMS in runtime.

  • Check the Fiddler output for SMS XML API & it’s Status message delivered or not.

 

  • Status shows the SMS has been delivered so check in handset the received SMS from your ASP.NET Web Application.
