发邮件怎么老发不成功？代码不多，高手过来接分
protected void btnSend_Click(object sender, EventArgs e){
string mailto = this.TextTo.Text;
string mailfrom = this.TextFrom.Text;
string mailpwd = this.TextPwd.Text;
string mailtile = this.Texttile.Text;
string mailcontent = this.TextContent.Text;
if ( SendMailTo(mailto, mailfrom, mailpwd, mailtile, mailcontent))
{
this.Label1.Text = "发送成功";
}
else
{
this.Label1.Text = "发送失败";
}
}
public bool SendMailTo(string mailto,string mailfrom,string mailpwd,string mailtile,string mailcontent)
{
try
{
MailMessage message = new MailMessage(mailfrom, mailto, mailtile, mailcontent);
message.BodyEncoding = System.Text.Encoding.GetEncoding("GB2312");
message.IsBodyHtml = true;
SmtpClient client = new SmtpClient("smtp.126.com");
client.Credentials = new NetworkCredential(mailfrom, mailpwd);
client.Send(message);
return true;
}
catch
{
return false;
}
}
catch 邮箱不可用。 服务器响应为: Óû§±»Ëø¶¨ --------------------编程问答-------------------- public bool SendMailTo(string mailto,string mailfrom,string mailpwd,string mailtile,string mailcontent)

--------------------编程问答-------------------- 原来是126的问题 --------------------编程问答-------------------- 换成STMP.163.com的试一下，我曾经用163的做过，可以发送 --------------------编程问答-------------------- 用Tom的可以~ --------------------编程问答-------------------- 126smtp服务器有问题 反正以前是pop服务有问题
还有就是可能需要ssl --------------------编程问答-------------------- 这种情况大多是smtpserver的问题.换其他的试试,我原来做这个的时候用过21cn的可以 --------------------编程问答-------------------- 我用的smtp.163.com的smtpserver可以. 发邮件建议使用CDO组件来发送.好用 --------------------编程问答-------------------- 要不你改用IIS替发，其中必须注意的是你必须机子上装了SMTP服务，并启动该服务。才可以
用这个肯定行的 --------------------编程问答-------------------- 能不能发个可以发的原代码啊，感激不尽！ --------------------编程问答--------------------
