c#smtp发送邮件修改版_用qq邮箱发邮件的例子

try
{
MailMessage mm = new MailMessage();
MailAddress Fromma = new MailAddress("xxxx@qq.com");
MailAddress Toma = new MailAddress("MMMMMMM@qq.com", null);
mm.From = Fromma;
//收件人
mm.To.Add("MMMMMM@qq.com");
//邮箱标题
mm.Subject = "Hello Dear:";
mm.IsBodyHtml = true;
//邮件内容
mm.Body = "你好Mr流星！";
//内容的编码格式
mm.BodyEncoding = System.Text.Encoding.UTF8;
//mm.ReplyTo = Toma;
//mm.Sender =Fromma;
//mm.IsBodyHtml = false;
mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnSuccess;
mm.CC.Add(Toma);
SmtpClient sc = new SmtpClient();
NetworkCredential nc = new NetworkCredential();
nc.UserName = "XXXXX@qq.com";//你的邮箱地址
nc.Password = "zzzzz";//你的邮箱密码,此处密码是xxxxx@qq.com邮箱的密码
   sc.UsedefaultCredentials = true;
sc.DeliveryMethod = SmtpDeliveryMethod.Network;
sc.Credentials = nc;
//如果这里报mail from address must be same as authorization user这个错误，是因为QQ邮箱没有开启SMTP，
//到邮箱设置下即可，在帐户下，如果是163邮箱的话，请修改为smtp.163.com
sc.Host = "smtp.qq.com";
sc.Send(mm);
}
catch (Exception ex)
{
throw new Exception(ex.Message);
