推荐答案
要发送邮件，您可以将此方法与您的Webmail势能一起使用
to send mail you can use this method with your webmail cardentials
public static Boolean SendingMail(string From, string To, string Subject, string Body)
{
try
{
MailMessage m = new MailMessage("sender@gmail.com", 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 = "mail.google.com";
NetworkCredential authinfo = new NetworkCredential("sender@gmail.com", "u1234");
smtp.UseDefaultCredentials = false;
smtp.Credentials = authinfo;
smtp.Send(m);
return true;
}
catch (Exception ex)
{
return false;
}
}
System.Net.Mail.MailMessage obj = new System.Net.Mail.MailMessage();
SmtpClient serverobj = new SmtpClient();
serverobj.Credentials = new NetworkCredential("YourEmailId", "YourPassword");
serverobj.Port = 587;
serverobj.Host = "smtp.gmail.com";
serverobj.EnableSsl = false;
obj = new System.Net.Mail.MailMessage();
obj.From = new MailAddress("anilmeets4u@gmail.com", "AgileLearning.com", System.Text.Encoding.UTF8);
obj.To.Add(ASPxtxtToUser.Text);
obj.CC.Add(ASPxTexttoCc.Text);
obj.Priority = System.Net.Mail.MailPriority.High;
obj.Subject = txtSubject.Text;
string date = DateTime.Now.ToString();
obj.Body = ASPxMemo1.Text;
serverobj.Send(obj);
lblsend.Text = "Your Message Send Sucessfully";
试试这个会很好用的
