使用 C# 添加附件到电子邮件

我正在使用此答案中的以下代码通过 Gmail 在 .NET 中发送电子邮件 https://stackoverflow.com/questions/32260/sending-email-in-net-through-gmail。我遇到的问题是在电子邮件中添加附件。如何使用下面的代码添加附件？

using System.Net.Mail;

var fromAddress = new MailAddress("[email protected] /cdn-cgi/l/email-protection", "From Name");
var toAddress = new MailAddress("[email protected] /cdn-cgi/l/email-protection", "To Name");
const string fromPassword = "fromPassword";
const string subject = "Subject";
const string body = "Body";

var smtp = new SmtpClient
{
    Host = "smtp.gmail.com",
    Port = 587,
    EnableSsl = true,
    DeliveryMethod = SmtpDeliveryMethod.Network,
    UseDefaultCredentials = false,
    Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
};
using (var message = new MailMessage(fromAddress, toAddress)
    {
        Subject = subject,
        Body = body
    })
{
    smtp.Send(message);
}

The message从您创建的对象new MailMessage方法调用有一个属性.Attachments.

例如：

message.Attachments.Add(new Attachment(PathToAttachment));
