System.Net.Mail.SmtpClient client = new SmtpClient();
client.Host = "smtp.163.com";
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential("NET.10", "kaixuan#310");
//星号改成自己邮箱的密码
client.DeliveryMethod = SmtpDeliveryMethod.Network;

System.Net.Mail.MailMessage message = new MailMessage("NET.10@163.com", "3511481@qq.com");
message.Subject = "测试";
message.Body = "用自己写的软件发的邮件！";
message.BodyEncoding = System.Text.Encoding.UTF8;
message.IsBodyHtml = true;
//添加附件
Attachment data = new Attachment(@"d:\nd.gif", System.Net.Mime.MediaTypeNames.Application.Octet);
message.Attachments.Add(data);
try
{
client.Send(message);
MessageBox.Show("Email successfully send.");
MessageBox.Show("发送成功!");
}
catch (Exception ex)
{
MessageBox.Show("Send Email Failed." + ex.ToString());
}
