c#关于web上收发邮件问题，散尽家财100分

Question

private void Button1_Click(object sender, System.EventArgs e)
{ 
                           string re="";
MailMessage amail=new MailMessage();
amail.To=this.TextBox1.Text;
amail.From=this.TextBox2.Text;
amail.Body=this.TextBox3.Text;
amail.Subject=this.TextBox4.Text;
amail.Priority=MailPriority.High;
amail.BodyFormat=MailFormat.Text;
SmtpMail.SmtpServer=this.TextBox5.Text.ToString();
try
{
SmtpMail.Send(amail);
re="good";
}
catch(Exception ex)
{
re="Email 发送失败"+ex.Message;
                            }
Response.Write("<script language='JavaScript'>window.alert('"+re+"');</script>");
}问题在哪里？点击按钮后就提示   Email 发送失败未能访问"CDO.Message"对象

Answer 1

那是因为没有通过身份验证的原因可以这样写:MailMessage sendPassMail=new MailMessage();
sendPassMail.From = "[email protected]";
sendPassMail.To = "[email protected]";
sendPassMail.Subject = "dfgdfgdfgdfgdfg";
sendPassMail.Priority = MailPriority.High;
sendPassMail.BodyFormat = MailFormat.Text;
sendPassMail.BodyEncoding = Encoding.Default;
sendPassMail.Body = "dgdgdfg" ;
SmtpMail.SmtpServer = "smtp.163.com";
sendPassMail.Fields["http://schemas.microsoft.com/cdo/configuration/sendusing"] = 2;
sendPassMail.Fields["http://schemas.microsoft.com/cdo/configuration/smtpauthenticate"]=1;
sendPassMail.Fields["http://schemas.microsoft.com/cdo/configuration/sendusername"]="sx_863";
sendPassMail.Fields["http://schemas.microsoft.com/cdo/configuration/sendpassword"]="这里写在密码";
//sendPassMail.Fields["http://schemas.microsoft.com/cdo/configuration/sendusing"] = "smtp3.163.com";
try
{
SmtpMail.Send(sendPassMail);

Response.Redirect("成功!");
}
catch(Exception ex)
{
Response.Redirect(ex.Message);
}已经通过..邮件发送成功

Answer 2

这不是登陆到别人的smtp服务器上去发的吗，SmtpMail.SmtpServer=this.TextBox5.Text.ToString();
这条语句不是这个意思?一定要自己的smtp服务器才能实现？

Answer 3

一定自己本机要有smtp服务吗 ?    fx_blog

Answer 4

未能访问"CDO.Message"对象是你的Windows没有安装CDO……
和自己还是别人的smtp服务器没关系

Answer 5

SmtpMail.SmtpServer = "smtp.163.com";
sendPassMail.Fields["http://schemas.microsoft.com/cdo/configuration/sendusing"] = 2;
sendPassMail.Fields["http://schemas.microsoft.com/cdo/configuration/smtpauthenticate"]=1;
sendPassMail.Fields["http://schemas.microsoft.com/cdo/configuration/sendusername"]="sx_863";
sendPassMail.Fields["http://schemas.microsoft.com/cdo/configuration/sendpassword"]="这里写在密码";
//sendPassMail.Fields["http://schemas.microsoft.com/cdo/configuration/sendusing"] = "smtp3.163.com";
