But it doesn't work. Is there any changes in this code that I have to do?
Please tell me any other way to send sms from desktop application or web application
Answer
I dont know way2sms but the easiest SMS API I have found is http://cp.bulksmsportal.co.za/sms_default.aspx
Code is really simple as well
public static void sendSMS(string Recepient, string Message)
{
//Recepient is the cellno in string format
StringBuilder sb = new StringBuilder();
sb.Append("http://www.mymobileapi.com/api5/http5.aspx?");
sb.Append("Type=sendparam");
sb.Append("&username={yourusername}");//add your username here
sb.Append("&password={yourpassword}");//add your password here
sb.AppendFormat("&numto={0}", Recepient);
string message = HttpUtility.UrlEncode(Message, ASCIIEncoding.ASCII);
sb.AppendFormat("&data1={0}", message);
try
{
////Create the request and send data to the SMS Gateway Server by HTTP connection
HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(sb.ToString());
//Get response from the SMS Gateway Server and read the answer
HttpWebResponse myResp = (HttpWebResponse)myReq.GetResponse();
System.IO.StreamReader respStreamReader = new System.IO.StreamReader(myResp.GetResponseStream());
string responseString = respStreamReader.ReadToEnd();
respStreamReader.Close();
myResp.Close();
}
catch (Exception ex)
{
}
}
