C#调用Mail发送QQ邮件

需要用到：

1.System.Net.Mail;

2.QQ邮箱的POP3/SMTP服务码

QQ邮箱的POP3/SMTP服务码获取方法：

1.打开qq邮箱：

2.进入设置页面--》账户：（往下翻）开启服务POP3/SMTP服务，QQ邮箱会给一个POP3/SMTP服务码保存下来

代码:

/// <summary>
       /// 发送邮件,成功返回true,否则false
       /// </summary>
       /// <param name="to">收件人</param>
       /// <param name="body">内容</param>
       /// <param name="title">标题</param>
       /// <param name="whichEmail">是否join</param>
       /// <param name="path">附件</param>
       /// <param name="Fname">姓名</param>
       /// <returns>结果</returns>
       public static bool SentMailHXD(string to, string body, string title, string whichEmail, string path, string Fname)
       {
           bool retrunBool = false;
           MailMessage mail = new MailMessage();
           SmtpClient smtp = new SmtpClient();
           string strFromEmail = "";//你的邮箱
           string strEmailPassword = "";//QQPOP3/SMTP服务码
           try
           {
               mail.From = new MailAddress("" + Fname + "<" + strFromEmail + ">");
               mail.To.Add(new MailAddress(to));
               mail.BodyEncoding = Encoding.UTF8;
               mail.IsBodyHtml = true;
               mail.SubjectEncoding = Encoding.UTF8;
               mail.Priority = MailPriority.Normal;
               mail.Body = body;
               mail.Subject = title;
               smtp.Host = "smtp.qq.com";
               smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
               smtp.Credentials = new System.Net.NetworkCredential(strFromEmail, strEmailPassword);
               //发送邮件
               smtp.Send(mail);   //同步发送
               retrunBool = true;
           }
           catch (Exception ex)
           {
               retrunBool = false;
           }
           // smtp.SendAsync(mail, mail.To); //异步发送 （异步发送时页面上要加上Async="true" ）
           return retrunBool;
       }

调用方法即可：

SentMailHXD("收件人", "内容, "标题", "抄送", "附件（附件方法我移除了）", "你的姓名");</span>
