通過C＃發送郵件

Question

我正在嘗試使用gmail stmp服務器通過C＃向自己發送電子郵件，但我收到了來自gmail團隊的電子郵件，內容是： “ Google剛剛阻止了不安全的應用訪問您的Google帳戶。” 。 現在，我更改了設置，以允許安全性較低的應用登錄google，但無法向自己發送電子郵件。以下是我的代碼。

    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();
    }

我也嘗試過使用Yahoo帳戶進行同樣的操作。然后我也沒有收到任何電子郵件。 我已將端口更改為465，將smtphost更改為“ mail.yahoo.com”，並將電子郵件地址更改為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);
}

您已使用此代碼。 它正在運行代碼。

轉到Google帳戶設置，並允許安全性較低的應用程序。 https://myaccount.google.com/u/1/security?utm_source=OGB#signin在底部的“允許安全程度較低的應用程序”滑塊是您需要使用的滑塊。

默認的Google SMTP設置在此處 。
