无法使用Mailkit从xamarin.android应用程序发送电子邮件

Question

我无法使用MailKit库jstedfast从xamarin.android应用程序发送电子邮件。

我使用下面的代码：

try 
{ 
    //From Address 
    string FromAddress = "from_sender@gmail.com"; 
    string FromAdressTitle = "Email Title"; 
    //To Address 
    string ToAddress = "to_receiver@gmail.com"; 
    string ToAdressTitle = "Address Title"; 
    string Subject = "Subject of mail"; 
    string BodyContent = "Body of email"; 

    //Smtp Server 
    string SmtpServer = "smtp.gmail.com"; 
    //Smtp Port Number 
    int SmtpPortNumber = 587; 

    var mimeMessage = new MimeMessage(); 
    mimeMessage.From.Add(new MailboxAddress(FromAdressTitle, FromAddress)); 
    mimeMessage.To.Add(new MailboxAddress(ToAdressTitle, ToAddress)); 
    mimeMessage.Subject = Subject; 
    mimeMessage.Body = new TextPart("plain") 
    { 
     Text = BodyContent 

    }; 

    using (var client = new SmtpClient()) 
    { 

     client.Connect(SmtpServer, SmtpPortNumber, false); 
     // Note: only needed if the SMTP server requires authentication 
     // Error 5.5.1 Authentication 
     client.AuthenticationMechanisms.Remove("XOAUTH2"); 
     client.Authenticate("from_sender@gmail.com", "password"); 
     client.Send(mimeMessage); 
     Console.WriteLine("The mail has been sent successfully !!"); 
     Console.ReadLine(); 
     client.Disconnect(true); 

    } 

} 
catch (Exception ex) 
{ 
    string message = ex.Message; 
} 

当我运行从我的应用程序的代码，它抛出一个异常：

MailKit.Security.AuthenticationException

我在想什么这段代码。任何人都可以帮助我！

使用MAILMESSAGE类。

using System.Net.Mail; 

。

MailMessage mail = new MailMessage("example@gmail.com", "example@gmail.com", "Title","Body"); 
        SmtpClient client = new SmtpClient(); 
        client.Host = ("smtp.gmail.com"); 
        client.Port = 587; //smtp port for SSL 
        client.Credentials = new System.Net.NetworkCredential("example@gmail.com", "password"); 
        client.EnableSsl = true; //for gmail SSL must be true 

        client.Send(mail);
