Question

MailDefinition类仅适用于ASP吗？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？

当然，您应该可以从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);
    }
}

MailDefinition类是否仅用于ASP？
