2）：如何在Asp.Net中调用此Service去创建对应的Lead，请看如下代码：

            try
            {
                StringBuilder data = new StringBuilder();
                data.Append("oid=[youroid]");
                data.Append("&first_name=" + Server.UrlEncode(this.txtFirstName.Text));
                data.Append("&last_name=" + Server.UrlEncode(this.txtLastName.Text));
                data.Append("&email=" + Server.UrlEncode(this.txtEmail.Text));

                string url = "https://test.salesforce.com/servlet/servlet.WebToLead?encoding=UTF-8";
                HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
                req.Method = "POST";
                req.ContentType = "application/x-www-form-urlencoded";
                byte[] buffer = Encoding.UTF8.GetBytes(data.ToString());
                req.ContentLength = buffer.Length;
                using (Stream reqst = req.GetRequestStream())
                {
                    reqst.Write(buffer, 0, buffer.Length);
                }

                WebResponse response = req.GetResponse();
            }
            catch (Exception ex)
            {

            }
