c# - 如何在 Asp.Net 中发送带附件的电子邮件

Question

我需要在 asp.net 中的电子邮件中附加一张图片，该文件已添加到解决方案资源管理器中，但我不知道如何将其添加到我的电子邮件中，请指导我

我当前的代码如下

public void SendMail()
{
    try
    {
        string receiverEmailId = "name@exmp.com";
        string senderName = ConfigurationManager.AppSettings["From"].ToString();
        string mailServer = ConfigurationManager.AppSettings["SMTPServer"].ToString(); ;
        string senderEmailId = ConfigurationManager.AppSettings["SMTPUserName"].ToString();
        string password = ConfigurationManager.AppSettings["SMTPPasssword"].ToString();
        var fromAddress = new MailAddress(senderEmailId, senderName);
        var toAddress = new MailAddress(receiverEmailId, "Alen");
        string subject = "subject";
        string body = "body.";
        var smtp = new SmtpClient
        {
            Host = "smtp.gmail.com",
                    Port = 587,
                    EnableSsl = true,
                    DeliveryMethod = SmtpDeliveryMethod.Network,
                    Credentials = new NetworkCredential(fromAddress.Address, password)
        };
        using (var message = new MailMessage(fromAddress, toAddress)
        {
            Subject = subject,
            Body = body
        })
        {
            smtp.Send(message);
        }
    }
    catch (Exception ex)
    {
    }
}

你检查了吗MailMessage.Attachments属性(参见 MSDN)？

// create attachment and set media Type
//      see http://msdn.microsoft.com/de-de/library/system.net.mime.mediatypenames.application.aspx
Attachment data = new Attachment(
                         "PATH_TO_YOUR_FILE", 
                         MediaTypeNames.Application.Octet);
// your path may look like Server.MapPath("~/file.ABC")
message.Attachments.Add(data);
