推荐答案

public static Boolean SendingMail(string From, string To, string Subject, string Body)
    {

            try
            {
                MailMessage m = new MailMessage("Uma<[email protected]>", To);
                m.Subject = Subject;
                m.Body = Body;
                m.IsBodyHtml = true;
                m.From = new MailAddress(From);

                m.To.Add(new MailAddress(To));
                SmtpClient smtp = new SmtpClient();
                smtp.Host = "smtp.gmail.com";

                NetworkCredential authinfo = new NetworkCredential("[email protected]","password");
                smtp.UseDefaultCredentials = false;
                smtp.Credentials = authinfo;
                smtp.Send(m);
                return true;




            }
            catch (Exception ex)
            {
                return false;
            }
        }

public string SendMail(string toList, string from, string ccList, string subject, string body)
{

    MailMessage message = new MailMessage();
    SmtpClient smtpClient = new SmtpClient();
    string msg = string.Empty;
    try
    {
        MailAddress fromAddress = new MailAddress(from);
        message.From = fromAddress;
        message.To.Add(toList);
        if (ccList != null && ccList != string.Empty)
            message.CC.Add(ccList);
        message.Subject = subject;
        message.IsBodyHtml = true;
        message.Body = body;
        smtpClient.Host = "smtp.gmail.com";   // We use gmail as our smtp client
        smtpClient.Port = 587;
        smtpClient.EnableSsl = true;
        smtpClient.UseDefaultCredentials = true;
        smtpClient.Credentials = new System.Net.NetworkCredential("Your Gmail User Name", "Your Gmail Password");

        smtpClient.Send(message);
        msg = "Successful<BR>";
    }
    catch (Exception ex)
    {
        msg = ex.Message;
    }
