Question

我正在开发一个ASP .Net网站我的一个ASPX页面包含一个按钮单击此按钮后，我想使用Gmail SMTP服务器发送电子邮件我想将我的Gmail帐户用作凭据。

这是按钮的点击事件处理程序：

protected void m_myButton_Click(object p_sender, EventArgs p_args)
{
    string l_subject = "My subject";

    StringBuilder l_builder = new StringBuilder();
    // ...
    string l_body = l_builder.ToString();

    string l_host = ConfigurationManager.AppSettings["SmtpHost"];
    int l_port = int.Parse(ConfigurationManager.AppSettings["SmtpPort"]);

    NameValueCollection l_smtpAccount = (NameValueCollection)ConfigurationManager.GetSection("smtpAccount");
    string l_address = l_smtpAccount["SmtpAddress"];
    string l_password = l_smtpAccount["SmtpPassword"];

    MailMessage l_mail = new MailMessage();
    l_mail.From = new MailAddress(l_address);
    l_mail.To.Add(l_address);
    l_mail.Subject = l_subject;
    l_mail.Body = l_body;

    SmtpClient l_smtp = new SmtpClient();
    l_smtp.Host = l_host; // l_host = "smtp.gmail.com"
    l_smtp.Port = l_port; // l_port = 587
    l_smtp.EnableSsl = true;
    l_smtp.UseDefaultCredentials = false;
    l_smtp.Credentials = new NetworkCredential(l_address, l_password);

    l_smtp.Send(l_mail);
}

命令行l_smtp.Send（l_mail）失败引发了一个SMTP异常，并且InnerException属性通知我（从法语翻译成英语）：由于目标计算机拒绝连接，因此没有建立任何连接173.194.67.108:587

我的代码基于此页面上的代码：http://www.codeproject.com/Questions/254743/sending-email-in-asp-net-using-smtp-gmail-server

非常感谢任何帮助

Answer 1

试试这个......

 protected void Button1_Click(object sender, EventArgs e)
{
 MailMessage mail = new MailMessage();
 mail.To.Add("Email ID where email is to be send");
 mail.To.Add("Another Email ID where you wanna send same email");
 mail.From = new MailAddress("YourGmailID@gmail.com");
 mail.Subject = "Email using Gmail";

 string Body = "Hi, this mail is to test sending mail"+ 
             "using Gmail in ASP.NET";
 mail.Body = Body;

  mail.IsBodyHtml = true;
 SmtpClient smtp = new SmtpClient();
 smtp.Host = "smtp.gmail.com"; //Or Your SMTP Server Address
 smtp.Credentials = new System.Net.NetworkCredential
   ("YourUserName@gmail.com","YourGmailPassword");
//Or your Smtp Email ID and Password
 smtp.EnableSsl = true;
 smtp.Send(mail);
 }

Answer 2

由于目标计算机已拒绝73.194.67.108:587

，因此未建立任何连接

尝试其他SMTP端口：465

Answer 3

我按照Rup的建议关闭了我的防病毒程序，我没有任何例外我将在我的防病毒程序中创建一个自定义规则，以允许我的ASP .Net网站和Gmail SMTP服务器之间的通信。
