//如果没有上述三行代码,则出现如下错误提示:服务器拒绝了一个或多个收件人地址。服务器响应为: 554 : Client host rejected: Access denied
//SMTP地址
string smtp = "smtp." + From.Substring(From.IndexOf('@') + 1);
SmtpMail.SmtpServer = "smtp." + From.Substring(From.IndexOf('@') + 1);
//开始发送邮件
try

return "邮件发送成功!";
}
catch (System.Net.Mail.SmtpException ex)
{
return ex.Message;
}
//核心代码结束
}
}
然后下来是自己做的一个demo--
前台
function gei() {
var file_value = document.getElementById("File1").value;
document.getElementById("HiddenField1").value = file_value;
}
发给:
抄送:
密送:
主题:
内容:
附件:
后台:
protected void Button1_Click(object sender, EventArgs e)
{ //实例邮件帮助类
mailhelper mails = new mailhelper();
string filePath = HiddenField1.Value;
string a = mails.SendeEmal(TextBox1.Text, "邮件账号", "邮件密码", TextBox2.Text, TextBox4.Text, TextBox5.Text, filePath, TextBox3.Text);
Label1.Text = a;
}
