Senden von E-Mails .NET über Gmail

Die obige Antwort nicht funktioniert. Sie müssen DeliveryMethod = SmtpDeliveryMethod.Network oder Sie kommen zurück mit einem "client wurde nicht authentifiziert" Fehler. Auch ist es immer eine gute Idee, um ein timeout.

Überarbeiteten code:

using System.Net.Mail;
using System.Net;

var fromAddress = new MailAddress("[email protected]", "From Name");
var toAddress = new MailAddress("[email protected]", "To Name");
const string fromPassword = "password";
const string subject = "test";
const string body = "Hey now!!";

var smtp = new SmtpClient
{
    Host = "smtp.gmail.com",
    Port = 587,
    EnableSsl = true,
    DeliveryMethod = SmtpDeliveryMethod.Network,
    Credentials = new NetworkCredential(fromAddress.Address, fromPassword),
    Timeout = 20000
};
using (var message = new MailMessage(fromAddress, toAddress)
{
    Subject = subject,
    Body = body
})
{
    smtp.Send(message);
}

Hier ist meine version: "Senden Sie E-Mail In C # Mithilfe Von Gmail".

      //Write the subject of ur mail
      const string subject = "Testing";

      const string body = "Hi This Is my Mail From Gmail";

      try
      {
        //we will use Smtp client which allows us to send email using SMTP Protocol
        //i have specified the properties of SmtpClient smtp within{}

        MailMessage message = new MailMessage(SendersAddress, ReceiversAddress, subject, body);

Ich hoffe, dieser code funktioniert einwandfrei. Sie können einen Versuch haben.

//Include this.                
using System.Net.Mail;

string fromAddress = "[email protected]";
string mailPassword = "*****";       //Mail id password from where mail will be sent.
string messageBody = "Write the body of the message here.";


//Create smtp connection.
SmtpClient client = new SmtpClient();
client.Port = 587;//outgoing port for the mail.
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
client.Timeout = 10000;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = new System.Net.NetworkCredential(fromAddress, mailPassword);


//Fill the mail form.
var send_mail = new MailMessage();

send_mail.IsBodyHtml = true;
//address from where mail will be sent.
send_mail.From = new MailAddress("[email protected]");
//address to which mail will be sent.           
send_mail.To.Add(new MailAddress("[email protected]");
//subject of the mail.
send_mail.Subject = "put any subject here";

send_mail.Body = messageBody;
client.Send(send_mail);

Quelle : Senden Sie E-Mail in ASP.NET C#

Nachfolgend ein Beispiel für einen funktionierenden code für das senden in einer E-mail mit C#, im Beispiel unten bin ich mit google ' s smtp-server.

Der code ist ziemlich selbsterklärend, ersetzen Sie E-Mail und Passwort mit email-Adresse und Passwort Werte.

public void SendEmail(string address, string subject, string message)
{
    string email = "[email protected]";
    string password = "put-your-GMAIL-password-here";

    var loginInfo = new NetworkCredential(email, password);
    var msg = new MailMessage();
    var smtpClient = new SmtpClient("smtp.gmail.com", 587);

    msg.From = new MailAddress(email);
    msg.To.Add(new MailAddress(address));
    msg.Subject = subject;
    msg.Body = message;
    msg.IsBodyHtml = true;

    smtpClient.EnableSsl = true;
    smtpClient.UseDefaultCredentials = false;
    smtpClient.Credentials = loginInfo;
    smtpClient.Send(msg);
}

nutzen Sie diesen Weg

MailMessage sendmsg = new MailMessage(SendersAddress, ReceiversAddress, subject, body); 
SmtpClient client = new SmtpClient("smtp.gmail.com");

client.Port = Convert.ToInt32("587");
client.EnableSsl = true;
client.Credentials = new System.Net.NetworkCredential("[email protected]","MyPassWord");
client.Send(sendmsg);

Ich hatte das gleiche Problem aber es wurde gelöst, indem man zu gmail Sicherheitseinstellungen und damit Weniger Sichere apps.
Der Code von Domenic & Donny funktioniert, aber nur, wenn Sie aktiviert ist, die Einstellung

Wenn Sie angemeldet sind (Google), die Sie Folgen können diese link und wechseln "Turn on" für "Zugriff für weniger sichere apps"

Hier ist eine Methode, um E-mail senden und abrufen von Anmeldeinformationen aus dem web.config:

public static string SendEmail(string To, string Subject, string Msg, bool bodyHtml = false, bool test = false, Stream AttachmentStream = null, string AttachmentType = null, string AttachmentFileName = null)
{
    try
    {
        System.Net.Mail.MailMessage newMsg = new System.Net.Mail.MailMessage(System.Configuration.ConfigurationManager.AppSettings["mailCfg"], To, Subject, Msg);
        newMsg.BodyEncoding = System.Text.Encoding.UTF8;
        newMsg.HeadersEncoding = System.Text.Encoding.UTF8;
        newMsg.SubjectEncoding = System.Text.Encoding.UTF8;

        System.Net.Mail.SmtpClient smtpClient = new System.Net.Mail.SmtpClient();
        if (AttachmentStream != null && AttachmentType != null && AttachmentFileName != null)
        {
            System.Net.Mail.Attachment attachment = new System.Net.Mail.Attachment(AttachmentStream, AttachmentFileName);
            System.Net.Mime.ContentDisposition disposition = attachment.ContentDisposition;
            disposition.FileName = AttachmentFileName;
            disposition.DispositionType = System.Net.Mime.DispositionTypeNames.Attachment;

            newMsg.Attachments.Add(attachment);
        }
        if (test)
        {
            smtpClient.PickupDirectoryLocation = "C:\\TestEmail";
            smtpClient.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.SpecifiedPickupDirectory;
        }
        else
        {
            //smtpClient.EnableSsl = true;
        }

        newMsg.IsBodyHtml = bodyHtml;
        smtpClient.Send(newMsg);
        return SENT_OK;
    }
    catch (Exception ex)
    {

        return "Error: " + ex.Message
             + "<br/><br/>Inner Exception: "
             + ex.InnerException;
    }

}

Und den entsprechenden Abschnitt in web.config:

<appSettings>
    <add key="mailCfg" value="[email protected]"/>
</appSettings>
<system.net>
  <mailSettings>
    <smtp deliveryMethod="Network" from="[email protected]">
      <network defaultCredentials="false" host="mail.exapmple.com" userName="[email protected]" password="your_password" port="25"/>
    </smtp>
  </mailSettings>
