C#，简单的邮件发送功能，邮件辅助类

这个帮助类只能发送简单的基本邮件，只能发送给多个用户，单一内容。不具有抄送功能，附件添加功能。功能代码如下，

    private void button3_Click(object sender, EventArgs e)    {      int result = SendEmail("123456@qq.com", "123456", new get='_blank'>string[] { "530794089@qq.com" }, "测试标题", "测试内容", "smtp.qq.com");      MessageBox.Show(result.ToString());    }    ///<summary>    /// 发送邮件    ///</summary>    ///<param name="sendEmailAddress">发件人邮箱</param>    ///<param name="sendEmailPwd">发件人密码</param>    ///<param name="msgToEmail">收件人邮箱地址</param>    ///<param name="title">邮件标题</param>    ///<param name="content">邮件内容</param>    ///<param name="host">邮件SMTP服务器</param>    ///<returns>0：失败。1：成功！</returns>    public static int SendEmail(string sendEmailAddress, string sendEmailPwd, string[] msgToEmail, string title, string content, string host)    {      //发件者邮箱地址      string fjrtxt = sendEmailAddress;      //发件者邮箱密码      string mmtxt = sendEmailPwd;      //主题      string zttxt = title;      //内容      string nrtxt = content;      string[] fasong = fjrtxt.Split('@');      //设置邮件协议      SmtpClient client = new SmtpClient(host);  //System.Net.Mail.SmtpClient      client.UseDefaultCredentials = false;      //通过网络发送到Smtp服务器      client.DeliveryMethod = SmtpDeliveryMethod.Network;      //通过用户名和密码 认证      client.Credentials = new NetworkCredential(fasong[0].ToString(), mmtxt); //System.Net.NetworkCredential      //QQ邮箱使用ssl加密，需要设置SmtpClient.EnableSsl 属性为True表示“指定 SmtpClient 使用安全套接字层 (SSL) 加密连接。”      client.EnableSsl = true;      //发件人和收件人的邮箱地址      MailMessage mmsg = new MailMessage();      mmsg.From = new MailAddress(fjrtxt);      for (int i = 0; i < msgToEmail.Length; i++)      {        mmsg.To.Add(new MailAddress(msgToEmail[i]));      }      //邮件主题      mmsg.Subject = zttxt;      //主题编码      mmsg.SubjectEncoding = Encoding.UTF8;      //邮件正文      mmsg.Body = nrtxt;      //正文编码      mmsg.BodyEncoding = Encoding.UTF8;      //设置为HTML格式      mmsg.IsBodyHtml = true;      //优先级      mmsg.Priority = MailPriority.High;      try      {        client.Send(mmsg);        return 1;      }      catch (Exception exss)      {        string msg = exss.Message;        return 0;      }    }
