不得不来CSDN问了，C#发邮件问题！！！！急！

[iMIssINGu]

用.net 2.0 的system.net.mail 发邮件 gmail的 下面代码没有提示错误 就是运行之后没反应 ！！！！
MailMessage testMail = new MailMessage();
testMail.From = new MailAddress(txtBoxFrom.Text);
testMail.To.Add(new MailAddress(txtBoxTo.Text));
testMail.Subject = txtBoxSubject.Text;
testMail.BodyEncoding = System.Text.Encoding.UTF8;
testMail.IsBodyHtml = true;
testMail.Body = richTxtBoxContent.Text;
testMail.Priority = MailPriority.High;

SmtpClient client = new SmtpClient(txtBoxSmtpSever.Text,587);//或者是587、465
client.UseDefaultCredentials = false;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.Credentials = new System.Net.NetworkCredential("****@gmail.com", "****");
client.EnableSsl = true;

try
{
client.Send(testMail);
}
catch (Exception ee)
{
richTxtBoxContent.Text = ee.Message;
}

没人给我说我会疯掉的！！！！

没反应去看邮箱吧，发成功了应该。我刚还以为gmail又不支持smtp了，还试了一下能发
我的代码是vb的跟你的基本一样

        Dim message As New System.Net.Mail.MailMessage

        message.From = New MailAddress("[e-mail]") '"Your DisplayName"
        message.To.Add(New MailAddress("[e-mail]")) ' the email you want to send email to
        Message.Subject = "A test email"

        message.IsBodyHtml = True
        message.BodyEncoding = System.Text.Encoding.UTF8
        Message.Body = "this is just a simple test!<br> Jack"
        message.Priority = MailPriority.High

        Dim client As New SmtpClient("smtp.gmail.com", 587)  ' // 587;//Gmail使用的端口
        client.Credentials = New System.Net.NetworkCredential("[e-mail]", "xxx") ' // Your user name & password
        client.EnableSsl = True  ' //经过ssl加密 

        Try
            client.Send(message)
            Debug.Print("邮件发送到" + message.To.ToString() + "<br>")

        Catch ex As Exception
            Debug.Print(ex.Message + "<br>" + ex.InnerException.Message)

        End Try

兄弟，是不是你发送完毕之后没有提示？所以你觉得没有反应哦？

MailMessage testMail = new MailMessage();
            testMail.From = new MailAddress(txtBoxFrom.Text);
            testMail.To.Add(new MailAddress(txtBoxTo.Text));
            testMail.Subject = txtBoxSubject.Text;
            testMail.BodyEncoding = System.Text.Encoding.UTF8;
            testMail.IsBodyHtml = true;
            testMail.Body = richTxtBoxContent.Text;
            testMail.Priority = MailPriority.High;
           
            SmtpClient client = new SmtpClient(txtBoxSmtpSever.Text,587);//或者是587、465
            client.UseDefaultCredentials = false;
            client.DeliveryMethod = SmtpDeliveryMethod.Network;
            client.Credentials = new System.Net.NetworkCredential("****@gmail.com", "****");
            client.EnableSsl = true;
   
            try
            {   
                this.Cursor = Cursors.WaitCursor;
                client.Send(testMail);
                this.Cursor = Cursors.Default;
                MessageBox.Show("发送成功");
            }
            catch (Exception ee)
            {
                this.Cursor = Cursors.Default;
                richTxtBoxContent.Text = ee.Message;
            }

你发送完输出个提示看看，应该是发过去了

[liujiayu10]

用JMAIL4吧 网上例子多的是，NET自带的东西都不太好用的

[chuxue1342]

代码貌似没有问题!为什么不去邮箱里面看看~~

[zzxap]

断点一下看执行到哪里看看

[zjs1109]

STMP问题吧。。

[xiaojing7]

增加个提示就OK了

[路人乙e]

条件：from == username

[I_loveCoding]

这么多的思路 ，值得学习一下。

[jdhlowforever]

学习下.跟ASP差不多.SMTP的都差不多吧.

可能是邮件帐号的问题，新帐号是发不出去的，最好用企业邮箱和一些经常使用并且邮箱使用时间较长的ID
