/// <param name="tomail">收件人邮箱地址</param>
private void Sendmail(string tomail)
{
var smtpClient = new SmtpClient();
var mailMessage = new MailMessage();
smtpClient.Host = ConfigurationManager.AppSettings["MailHost"];//指定发送邮件的服务器地址或IP，如smtp.163.com
var mailname = ConfigurationManager.AppSettings["MailName"];//发件人邮箱用户名
var mailpsd = ConfigurationManager.AppSettings["MailPassWord"];//发件人邮箱密码
smtpClient.Port = 25;//指定发送邮件端口
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = new System.Net.NetworkCredential(mailname, mailpsd);
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
mailMessage.BodyEncoding = Encoding.UTF8;
mailMessage.IsBodyHtml = true;//是否为html格式
mailMessage.Priority = MailPriority.High;//发送邮件的优先等级
mailMessage.From = new MailAddress(mailname);
mailMessage.To.Add(tomail);
mailMessage.Subject = "发送邮件测试";//邮件主题
string[] file = {"c:\\log.7z","c:\\log.rar"};
mailMessage.Attachments.Clear();
//添加邮件附件，可发送多个文件
foreach (var filename in file)
{
mailMessage.Attachments.Add(new Attachment(filename, MediaTypeNames.Application.Octet));
}
mailMessage.Body = GetBody();//邮件内容
try
{
smtpClient.Send(mailMessage);
}
