Question

我正在尝试使用gmail stmp服务器通过C＃向我自己发送电子邮件，但我收到了来自gmail团队的电子邮件，说“Google刚刚屏蔽了一个不太安全的应用访问您的Google帐户。”。现在我已经更改了设置以允许不太安全的应用程序登录谷歌，但我无法向自己发送电子邮件。这是我的代码。

    private static string sendMail(System.Net.Mail.MailMessage mm)
    {
        try
        {
            string smtpHost = "smtp.gmail.com";
            string userName = "myemail@gmail.com";//write your email address
            string password = "xxxxxx";//write password
            System.Net.Mail.SmtpClient mClient = new System.Net.Mail.SmtpClient();
            mClient.Port = 587;
            mClient.EnableSsl = true;
            mClient.UseDefaultCredentials = false;
            mClient.Credentials = new NetworkCredential(userName, password);
            mClient.Host = smtpHost;
            mClient.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
            mClient.Send(mm);
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.ToString());
        }

        return "Send Sucessfully";
    }
private void f()
      {
          i = i + 1;
        string sysName = string.Empty;
        string sysUser = string.Empty;
        System.Net.Mail.MailAddress toAddress = new System.Net.Mail.MailAddress("myemail@gmail.com");
        System.Net.Mail.MailAddress fromAddress = new System.Net.Mail.MailAddress("myemail@gmail.com");
        System.Net.Mail.MailMessage mm = new System.Net.Mail.MailMessage(fromAddress, toAddress);
        sysName = System.Security.Principal.WindowsIdentity.GetCurrent().Name.ToString();
        sysUser = System.Security.Principal.WindowsIdentity.GetCurrent().User.ToString();
        mm.Subject = sysName + " " + sysUser;
        string filename = string.Empty;
        mm.IsBodyHtml = true;
        mm.BodyEncoding = System.Text.Encoding.UTF8;
        MessageBox.Show(sendMail(mm).ToString());
        //sendMail(mm);
    }
    private void Form1_Load(object sender, EventArgs e)
    {
        f();
    }

我也尝试过我的雅虎帐户。然后我也没有收到任何电子邮件。我已将端口更改为465并将smtphost更改为“mail.yahoo.com”，并将电子邮件地址更改为mymail@yahoo.com

protected void SendMail()
{
    // Gmail Address from where you send the mail
    var fromAddress = "Gmail@gmail.com";
    // any address where the email will be sending
    var toAddress = YourEmail.Text.ToString(); 
    //Password of your gmail address
    const string fromPassword = "Password";
     // Passing the values and make a email formate to display
    string subject = YourSubject.Text.ToString();
    string body = "From: " + YourName.Text + "\n";
    body += "Email: " + YourEmail.Text + "\n";
    body += "Subject: " + YourSubject.Text + "\n";
    body += "Question: \n" + Comments.Text + "\n";
    // smtp settings
    var smtp = new System.Net.Mail.SmtpClient();
    {
        smtp.Host = "smtp.gmail.com";
        smtp.Port = 587;
        smtp.EnableSsl = true;
        smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
        smtp.Credentials = new NetworkCredential(fromAddress, fromPassword);
        smtp.Timeout = 20000;
    }
    // Passing values to smtp object
    smtp.Send(fromAddress, toAddress, subject, body);
}

您已使用此代码。它正在运行代码。

转到Google帐户设置，并允许安全性较低的应用程序。 https://myaccount.google.com/u/1/security?utm_source=OGB#signin 在底部＆＃34;允许不太安全的应用程序＆＃34;滑块是您需要使用的滑块。

默认的Google SMTP设置为here。
