Question

我正在制作一个c＃和Windows Forms（经典Windows应用程序，如记事本，油漆等）应用程序，它具有获取屏幕截图并通过邮件发送的功能。但是，它现在只能拍摄6张照片（我可以添加更多，但我不想添加更多代码，我想以编程方式制作），如何使其发送更多或更少，如用户设置，外部应用程序？

Timer1发送邮件。 Timer2截图。 resimoran是一个int，它是调整大小的图像比例，默认为1。 counter是一个int，它现在正在运作......

这是我的代码：

    private Bitmap Screenshot()
    {
        Bitmap Screenshot = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
        Graphics GFX = Graphics.FromImage(Screenshot);
        GFX.CopyFromScreen(Screen.PrimaryScreen.Bounds.X, Screen.PrimaryScreen.Bounds.Y, 0, 0, Screen.PrimaryScreen.Bounds.Size);
        return Screenshot;
    }

    void SendReport()
    {
        MailMessage mail;
        var fromAddress = new MailAddress(frommail, fromname);
        var toAddress = new MailAddress(alici, aliciname);
        string fromPassword = mailpass;

        var smtp = new SmtpClient
        {
            Host = mailhostaddress,
            Port = mailport,
            EnableSsl = sslenabled,
            DeliveryMethod = SmtpDeliveryMethod.Network,
            UseDefaultCredentials = usedefaultcre,
            Credentials = new NetworkCredential(fromAddress.Address, fromPassword)
        };
        using (mail = new MailMessage(fromAddress, toAddress)
        {
            Subject = konu + DateTime.Now,
            Body = "None of your businness!"
        })
        {
            mail.Attachments.Add(attach1);
            mail.Attachments.Add(attach2);
            mail.Attachments.Add(attach3);
            mail.Attachments.Add(attach4);
            mail.Attachments.Add(attach5);
            mail.Attachments.Add(attach6);

                    smtp.Send(mail);
        }
    }

private void timer1_Tick(object sender, EventArgs e)
    {
        SendReport();
    }

    private void timer2_Tick(object sender, EventArgs e)
    {
        counter++;
        if (counter == 1)
        {
            Bitmap ekrangor = Screenshot();
            Bitmap imagee = resizeImage(ekrangor, new Size(ekrangor.Width / resimoran, ekrangor.Height / resimoran));
            imagee.Save(@"screen1.jpg");
            System.IO.Stream streamer = new System.IO.MemoryStream();
            imagee.Save(streamer, System.Drawing.Imaging.ImageFormat.Jpeg);
            streamer.Position = 0;
            attach1 = new Attachment(streamer, "screen1.jpg");
        }
        else if (counter == 2)
        {
            Bitmap ekrangor = Screenshot();
            Bitmap imagee = resizeImage(ekrangor, new Size(ekrangor.Width / resimoran, ekrangor.Height / resimoran));
            imagee.Save(@"screen2.jpg");

            streamer.Position = 0;
            attach2 = new Attachment(streamer, "screen2.jpg");
        }
        else if (counter == 3)

            imagee.Save(@"screen3.jpg");
            System.IO.Stream streamer = new System.IO.MemoryStream();

        {
            Bitmap ekrangor = Screenshot();
            Bitmap imagee = resizeImage(ekrangor, new Size(ekrangor.Width / resimoran, ekrangor.Height / resimoran));

public static Bitmap resizeImage(Bitmap imgToResize, Size size)
        {
            return (new Bitmap(imgToResize, size));
        }

而且，请用C＃给我答案，而不是英文！（不是“这样做：MSDN bla bla”，但“试试这个虚空lolnocodezhere（）{}”）

Answer 1

List<T>是你的朋友。

你将它声明在适当的地方

List<Attachment> attachments = new List<Attachment>();

然后你用一个

替换你的6个街区

attachments.Add(new Attachment(streamer, "screen.jpg");)

当合适的时间到来时，你会做一个

foreach(Attachment a in attachments ) mail.Attachments.Add(a);

成功发送邮件后，您可以删除这样的集合：

attachments.Clear();

由你来控制计数器，屏幕图像等等。

顺便说一下：mail.Attachments就是这样一个集合，也许你想直接使用它......？

在c＃windows窗体中添加多个附件到邮件
