namespace Mail
{
 public static class mail
 {
 public static void GetparaBySendmail(string mailaddress,string title,string file ,string content,string fromname,string pwd)
 {
 MailMessage mails = new MailMessage(); //创建邮件类
 string fileone;
 mails.From = new MailAddress(fromname, fromname, System.Text.Encoding.UTF8);//说明指定发件人的信息 收件的地址
 mails.Subject = title;
 fileone=file;
 if (file!=String.Empty) //判断文件是否为空
 {
 AlternateView avfile = new AlternateView(fileone);

 mails.AlternateViews.Add(avfile);
 }
 mails.BodyEncoding = System.Text.Encoding.UTF8;//文件编码
 mails.IsBodyHtml = true;//是否为HTML格式
 mails.Body = content; //发送的内容


 mails.Priority = MailPriority.High;//优先级
 SmtpClient smtp = new SmtpClient(); //发送邮件的协议
 smtp.UseDefaultCredentials=true;
 smtp.Credentials = new System.Net.NetworkCredential(fromname, pwd);//发送人的邮箱
 string host = fromname.Substring(fromname.LastIndexOf("@")+1);
 smtp.Host ="smtp."+ host;
 string[] maillist= mailaddress.Split(';');
 for (int i = 0; i < maillist.Length; i++)
 {
 mails.To.Add(maillist[i]);//收件人的邮箱
 }

 try
 {
 smtp.EnableSsl = true;//ssl加密
 //smtp.Timeout = 1200;
 smtp.Send(mails);
 HttpContext.Current.Response.Write(" <script>alert('发送成功'); </script>");


 }
 catch (Exception e)
 {

 HttpContext.Current.Response.Write(" <script>alert('"+e.Message+"'); </script>");
 }
