写个小例子,开发环境是VS2005

     public void send()
        {
            try
            {

                WebRequest webreq = WebRequest.Create("http://bj.bbcool.cn/");
                webreq.Credentials = CredentialCache.DefaultCredentials;
                HttpWebResponse response = (HttpWebResponse)webreq.GetResponse();
                MessageBox.Show(response.StatusDescription);

                Stream dataStream = response.GetResponseStream();
               
                StreamReader reader = new StreamReader(dataStream);
               
                string responseFromServer = reader.ReadToEnd();

                string myip = responseFromServer.Substring(responseFromServer.IndexOf("IP:"), 33);

                reader.Close();
                dataStream.Close();
                response.Close();

                MailAddress from = new MailAddress("[e-mail]");//发件人
                MailAddress to = new MailAddress("[e-mail]");//收件人
                MailMessage message = new MailMessage(from, to);
                message.Subject = "这是文件主题"; //文件主题
                message.Body = @"这是邮件正文";//邮件正文
                SmtpClient client = new SmtpClient();
                client.Credentials = new System.Net.NetworkCredential("邮件登录用户名", "邮件登录密码");
                client.Host = "smtp.163.com";
                client.Send(message);

            }
            catch (Exception ee)
            {
                MessageBox.Show(ee.Message);
 
            }
