MailDefinition類僅用於ASP嗎？

Question

MailDefinition類僅用於ASP嗎？它似乎有我需要的一切，但顯然我需要在Web.Config文件中添加SMTP服務器信息。我想在WinForms應用程序中使用這個類。這可能嗎？

謝謝

當然，你應該可以在WinForms應用程序中使用它。您需要將SMTP主機名傳遞給System.Net.Mail.SmtpClient構造函數。類似這樣的：

using System.Net.Mail; 
using System.Web.UI.WebControls; 

// namespace etc 

private void SendEmail() 
{ 
    string to = "to@somewhere.com,to2@somewhere.com"; 

    MailDefinition mailDefinition = new MailDefinition(); 
    mailDefinition.IsBodyHtml = false; 

    string host = "smtpserver"; // Your SMTP server name. 
    string from = "from@somewhere.com"; 
    int port = -1;    // Your SMTP port number. Defaults to 25. 

    mailDefinition.From = from; 
    mailDefinition.Subject = "Boring email"; 
    mailDefinition.CC = "cc@somwhere.com,cc2@somwhere.com"; 

    List<System.Net.Mail.Attachment> mailAttachments = new List<System.Net.Mail.Attachment>(); 
    // Add any attachments here 

    using (MailMessage mailMessage = mailDefinition.CreateMailMessage(to, null, "Email body", new System.Web.UI.Control())) 
    { 
     SmtpClient smtpClient = new SmtpClient(host); 
     if (port != -1) 
     { 
      smtpClient.Port = port; 
     } 
     foreach (System.Net.Mail.Attachment mailAttachment in mailAttachments) 
     { 
      mailMessage.Attachments.Add(mailAttachment); 
     } 
     smtpClient.Send(mailMessage); 
    } 
}
