不懂，帮顶

mailMessage.To.Add(txt_To.Text);
没有add吧
还有 z456123这个应该是发送人的用户名吧换找个试试
253631203
smptClient.Credentials = new System.Net.NetworkCredential(mailMessage.From.Address, "z456123"); 在看看，是英文的吗

[z812183667]

上面的代码编译通过了啊！运行的时候才报的错误
z456123这个是我的密码啊！

[fuda_1985]

一般情况下，是因为mail的设置不对。。

[宝_爸]

我这里可以，至少不是在smptClient.Credentials = new System.Net.NetworkCredential(mailMessage.From.Address, "z456123");这句抛出的异常

Google了下，发现可能和主机名有关系，我的机器名士英文的

lz密码泄露了:)

[我在深圳搬砖-Justin]

这个是System.Net .Mail.Message 类的一个错误
System.Net.Mail 类发送电子邮件，收到 FormatException 消息。 当收件人电子邮件地址包含双引号，则会发生此问题
微软的官方网站，也报出了解决方案，不过还是用System.Web.Mail 发邮件比较实在点。

对啊System.Net .Mail.Message用这个发送邮件就是有个BUG，
但是怎么避免啊！
但是我不会用System.Web.Mail这个发送邮件，谁有源码给我到邮箱里面吧，谢谢了，[e-mail]

不过你最好先搞清楚原因是7楼说的还是5楼说的。

[z812183667]

MailMessage mail = new MailMessage();
           mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");
            mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "[e-mail]");
           mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "z456123");
            mail.BodyFormat = MailFormat.Text;
           mail.BodyEncoding = Encoding.UTF8;
            mail.From = "[e-mail]";
            mail.To = txt_To.Text;
            mail.Subject = txt_Subject.Text;
            mail.Body = txt_Msg.Text ;

            SmtpMail.SmtpServer = "smtp.qq.com";
            SmtpMail.Send(mail);

我这样写对吗？

[宝_爸]

我这里没有安装net1.1,因此没法测试，
不过应该加入Credentials 相关的东西。
不幸的是，我搜索不到相关内容。

[xupeihuagudulei]

可能pop3没设置对

[宝_爸]

[Quote=引用 13 楼 xupeihuagudulei 的回复:]

[/Quote]

pop3是接收邮件的协议

[z812183667]

都不行啊！
好是不行啊！

[z812183667]

谢谢大家了，终于成功了！
