c# - MailDefinition 类是否仅用于 ASP？

Question

是 MailDefinition仅用于 ASP 的类？它似乎拥有我需要的一切，但显然我需要在 Web.Config 文件中添加 SMTP 服务器信息。我想在 WinForms 应用程序中使用此类。这可能吗？

谢谢

当然，您应该能够从 WinForms 应用程序中使用它。您需要将 SMTP 主机名传递给 System.Net.Mail.SmtpClient 构造函数。像这样:

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);
    }
}
