使用C＃.Net錯誤發送電子郵件5.7.1

Question

我試圖創建一個函數，使用時將電子郵件發送到目標地址。

我的電子郵件型號：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Net; 
using System.Net.Mail; 
using System.Security; 

namespace myspecial.net.Models 
{ 
    public class EmailModel 
    { 
     // Sender email and recipient email 
     public MailAddress Sender { get; set; } 
     public IEnumerable<MailAddress> Recipient { get; set; } 
     // Subject and message 
     public String Subject { get; set; } 
     public String Body { get; set; } 
     // Attachment Files 
     public String AttachmentPath { get; set; } 
     // Login Information 
     public String UserName { get; set; } 
     public String Password { get; set; } 
     // Simple Mail Transfer Protocol (SMTP) provider and port 
     public String SmtpServer { get; set; } 
     public Int32 SMTPport { get; set; } 
     // Post Office Protocol (POP) version 3 provider and port 
     public String POP3Server { get; set; } 
     public Int32 POP3port { get; set; } 
     // Secure Sockets Layer 
     public Boolean SSL { get; set; } 
    } 
} 

我的控制器：

/// <summary> 
/// E-Mail's to the address. Before using this function fill the email model. 
/// </summary> 
public void Email(EmailModel mailer) 
{ 
    MailMessage mail = new MailMessage(); 
    // Standart required mail information 
    mail.From = mailer.Sender; 
    mail.Sender = mailer.Sender; 
    // Recipients 
    foreach (MailAddress rcpnt in mailer.Recipient.ToList()) 
    { mail.To.Add(rcpnt); } 
    // Subject 
    mail.Subject = mailer.Subject; 
    // Body 
    mail.Body = mailer.Body; 
    // Optional Attachment 
    if (mailer.AttachmentPath != null || mailer.AttachmentPath.Trim() != "") 
    { 
     System.Net.Mail.Attachment attachment; 
     attachment = new System.Net.Mail.Attachment(mailer.AttachmentPath.Trim()); 
     mail.Attachments.Add(attachment); 
    } 
    // Important (Simple Mail Transfer Protocol) 
    SmtpClient SmtpServer = new SmtpClient(mailer.SmtpServer,mailer.SMTPport); 
    SmtpServer.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; 
    SmtpServer.Credentials = new System.Net.NetworkCredential(mailer.UserName, mailer.Password, mailer.SmtpServer); 
    SmtpServer.Port = mailer.SMTPport; 
    SmtpServer.EnableSsl = mailer.SSL; 
    ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; }; 
    // Send Mail 
    SmtpServer.Send(mail); 
} 

我如何使用它：

 // Send as mail 
     EmailModel mail = new EmailModel(); 
     // Mail addresses to send 
     MailAddress[] addressler = new MailAddress[] { new MailAddress("berkeryuceer@yahoo.com") }; 
     // Options here 
     mail.SMTPport = 465; // Port // 465 // 26 // 25 // 366 // 587 
     mail.SmtpServer = "smtp.gmail.com"; // Server 
     mail.UserName = "MyGmailAddress@gmail.com"; // UserName 
     mail.Password = "**********"; // Password 
     mail.SSL = true; // Secure Sockets Layer 
     // Mail 
     mail.Sender = new MailAddress("MyGmailAddress@gmail.com"); // Sender (From) 
     mail.Recipient = addressler; // Recipient (To) 
     mail.Subject = "Some subject here.."; 
     mail.Body = "Some blabla bla blablabla blabla here..."; 
     // Optional Attachment // Attach excel file. 
     mail.AttachmentPath = ExportToExcelForMail(id).ToString(); 
     Email(mail); 

在我的web項目中創建一個報告的Excel文件，並想送它給我自己附上一封電子郵件。我不知道什麼是錯的或者什麼，我在這裏失蹤。一切似乎有效的給我，但我仍收到此錯誤：

堆棧跟蹤：

所以我是什麼？在這裏失蹤？怎麼了？我如何解決這個問題？

Answer 1

您可以使用下面的代碼：

/// <summary> 
    /// Sends mail with authentification 
    /// </summary> 
    /// <param name="recipients"></param> 
    /// <param name="from"></param> 
    /// <param name="subject"></param> 
    /// <param name="body"></param> 
    /// <param name="isHTMLbody"></param> 
    /// <param name="SMTPhost"></param> 
    /// <param name="priority"></param> 
    /// <param name="credentials"></param> 
    /// <param name="port"></param> 
    /// <param name="enableSsl"></param> 
    static void SendMailWithAuthentication(List<string> recipients, string from, string subject, string body, bool isHTMLbody, 
     string SMTPhost, System.Net.Mail.MailPriority priority, System.Net.NetworkCredential credentials, int? port, bool enableSsl) 
    { 
     System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage(); 
     foreach (string recipient in recipients) 
     { 
      message.To.Add(recipient); 
     } 
     message.SubjectEncoding = Encoding.UTF8; 
     message.BodyEncoding = Encoding.UTF8; 
     message.Subject = subject; 
     message.From = new System.Net.Mail.MailAddress(from); 
     message.IsBodyHtml = isHTMLbody; 
     message.Body = body; 
     message.Priority = priority; 
     System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient(); 
     client.Credentials = credentials; 
     client.Host = SMTPhost; 
     if (port != null) 
     { 
      client.Port = (int)port; 
     } 
     client.EnableSsl = enableSsl; 
     client.Send(message); 
     message.Dispose(); 
    } 

而且這是你應該如何使用它的Gmail：

 string subject = "my subject"; 
     string body = "my html body"; 
     int port = 587; 
     string SMTPhost = "smtp.gmail.com"; 
     string sender = "my@email.com"; 
     System.Net.Mail.MailPriority mPriority = System.Net.Mail.MailPriority.Low;   
     List<string> recipients = new List<string>(){"some@reciever.com"}; 
     bool enableSSL = true; 
     System.Net.NetworkCredential credentials = new System.Net.NetworkCredential("UserName","Password"); 
     SendMailWithAuthentication(recipients, sender, subject, body, true, 
      SMTPhost, 
      mPriority, credentials, 
      enableSSL);
