"Content-Type","application/x-www-form-urlencoded"

C#

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;
 
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=yourapi username & 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=<?xml%20version=\"1.0\"%20encoding=\"ISO-8859-1\"?><user%20username>    }
