C# WinForm发送Email邮件
做这个发送邮件前，先去qq邮箱设置开启smtp服务，如图：记住第一个服务pop3/smtp的授权码。
private void simpleButton3_Click(object sender, EventArgs e)
{//发送
SmtpClient client = new SmtpClient("smtp.qq.com"); //设置邮件协议
client.EnableSsl = true;
client.UseDefaultCredentials = false;//这一句得写前面
client.DeliveryMethod = SmtpDeliveryMethod.Network; //通过网络发送到Smtp服务器
client.Credentials = new NetworkCredential("[email protected]", "ywufrjewunxfbuuu"); //qq邮箱 和 授权码
MailMessage mmsg = new MailMessage(new MailAddress("[email protected]"), new MailAddress("[email protected]")); //发件人和收件人的邮箱地址
mmsg.Subject = "测试"; //邮件主题
mmsg.SubjectEncoding = Encoding.UTF8; //主题编码
mmsg.Body = "测试"; //邮件正文
mmsg.BodyEncoding = Encoding.UTF8; //正文编码
mmsg.IsBodyHtml = true; //设置为HTML格式
mmsg.Priority = MailPriority.High; //优先级
try
{
client.Send(mmsg);
MessageBox.Show("邮件已发成功");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
