  {
    /// <summary>
    /// 发件人
    /// </summary>
    public static string mailFrom { get; set; }

    /// <summary>
    /// 收件人

    /// 附件
    /// </summary>
    public static string[] attachmentsPath { get; set; }

    public static bool Send()
    {
      //使用指定的邮件地址初始化MailAddress实例
      MailAddress maddr = new MailAddress(mailFrom);

      //初始化MailMessage实例
      MailMessage myMail = new MailMessage();

      //向收件人地址集合添加邮件地址
      if (mailToArray != null)
      {
        for (int i = 0; i < mailToArray.Length; i++)
        {
          myMail.To.Add(mailToArray[i].ToString());
        }
      }

      //向抄送收件人地址集合添加邮件地址
      if (mailCcArray != null)
      {
        for (int i = 0; i < mailCcArray.Length; i++)
        {
          myMail.CC.Add(mailCcArray[i].ToString());
        }
      }
      //发件人地址
      myMail.From = maddr;

      //电子邮件的标题
      myMail.Subject = mailSubject;

      //电子邮件的主题内容使用的编码
      myMail.SubjectEncoding = Encoding.UTF8;

      //电子邮件正文
      myMail.Body = mailBody;

      //电子邮件正文的编码
      myMail.BodyEncoding = Encoding.Default;

      //电子邮件优先级
      myMail.Priority = MailPriority.High;

      //电子邮件不是html格式
      myMail.IsBodyHtml = isbodyHtml;

      //在有附件的情况下添加附件
      try
      {
        if (attachmentsPath != null && attachmentsPath.Length > 0)
        {
          Attachment attachFile = null;
          foreach (string path in attachmentsPath)
          {
            attachFile = new Attachment(path);
            myMail.Attachments.Add(attachFile);
          }
        }
      }
      catch (Exception err)
      {
        throw new Exception("在添加附件时有错误:" + err.Message);
      }

      SmtpClient client = new SmtpClient();

      //指定发件人的邮件地址和密码以验证发件人身份
      client.Credentials = new NetworkCredential(mailFrom, mailPwd);

      //设置SMTP邮件服务器
      //client.Host = "smtp." + myMail.From.Host;
      client.Host = host;

      //SMTP邮件服务器端口
      client.Port = port;

      //是否使用安全连接
      //client.EnableSsl = true;

      try
      {
        //将邮件发送到SMTP邮件服务器
        client.Send(myMail);
        return true;
      }
      catch (SmtpException ex)
      {
        string msg = ex.Message;
        return false;
      }

    }
