Hi guys,I'm trying to send sms using asp.net c#.

just a small background - its about sending members a message when they sign up,

but i am stuck with sending message ,

protected void sendmessagetomobile()

{

try

{

string uid = "9999999999";

string password = "****";

string message = "Test";

string no = "9999999999";

//string no = TextBox1.Text;

HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://ubaid.tk/sms/sms.aspx?uid=" + uid + "&pwd=" + password + "&msg=" + message + "&phone=" + no + "&provider=way2sms");

HttpWebResponse myResp = (HttpWebResponse)req.GetResponse();

StreamReader respStreamReader = new System.IO.StreamReader(myResp.GetResponseStream());

string responseString = respStreamReader.ReadToEnd();

respStreamReader.Close();

myResp.Close();

Response.Write("sent");

}

catch (WebException ee) { }

}

I'm kinda still new to this programming,so any kind of help will be greatly helpful..

public string sendSmsByGetMethod()
        {
            using (var wb = new WebClient())
            {
                byte[] response = wb.UploadValues("https://URL", new NameValueCollection()
                  {
                   {"username" , username},
                     {"hash" , HashKey},
                   {"numbers" , txtMobileNo.Text},
                  {"message" , txtMessage.Text},
                   {"sender" , txtFrom.Text}, // not more than 11 charactor
                  {"test" , "true"}// for testing purpose

                   });
                string result = System.Text.Encoding.UTF8.GetString(response);
                return result;

            }
        }

Hi...

For sending messages on mobile from ASP.NET Portal, can we do it without using a 3rd party dll ??

Have you got any error on your code? If yes, let us know. Apart from that, you are using ubaid API service on your code, which is Free. I'm not sure about that SMS service is working fine. Because i believe that nothing comes as free. ASFAIK, there is no "trusted" FREE SMS gateway which allow to sent FREE SMS from your application. I have already searched the same for one of my project. But no luck. Before you start, i suggest to go thru this link, which give some basics about SMS gateways. So you need to buy SMS from SMS Service providers (SMS Gateway). This google search will provide a list of SMS providers and based on your financial status you can go with.
