现在检查此电子邮件正文有多个 src="cid:DDMMYYYY_HHMMSS.gif" 这里所有文件都存储在我的本地 Web 应用程序文件夹中，名称唯一。我想将每个文件附加到电子邮件正文中。（不是电子邮件附件。电子邮件图像嵌入）。

如何处理多张图片...

请帮帮我..

Answer 1

你可以使用类似下面的东西...

private void button1_Click(object sender, EventArgs e)
    {
        try
        {
            MailMessage mail = new MailMessage();
            SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");

            mail.From = new MailAddress("your_email_address@gmail.com");
            mail.To.Add("to_address");
            mail.Subject = "Test Mail - 1";

            mail.IsBodyHtml = true;
            string htmlBody;

            htmlBody = "Write some HTML code here";

            mail.Body = htmlBody;

            SmtpServer.Port = 587;
            SmtpServer.Credentials = new System.Net.NetworkCredential("username", "password");
            SmtpServer.EnableSsl = true;

            SmtpServer.Send(mail);
            MessageBox.Show("mail Send");
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.ToString());
        }
    }

Answer 2

class Program
{
    static void Main(string[] args)
    {
        SmtpMail oMail = new SmtpMail("TryIt");
        SmtpClient oSmtp = new SmtpClient();

        // Set sender email address, please change it to yours
        oMail.From = "test@emailarchitect.net";

        // Set recipient email address, please change it to yours
        oMail.To = "support@emailarchitect.net";

        // Set email subject
        oMail.Subject = "test html email with attachment";

        // Your SMTP server address
        SmtpServer oServer = new SmtpServer("smtp.emailarchitect.net");

        // User and password for ESMTP authentication, if your server doesn't require
        // User authentication, please remove the following codes.            
        oServer.User = "test@emailarchitect.net";
        oServer.Password = "testpassword";

        // If your SMTP server requires SSL connection, please add this line
        // oServer.ConnectType = SmtpConnectType.ConnectSSLAuto;

        try
        {
           // Import html body and also import linked image as embedded images.
           oMail.ImportHtml( "<html><body>test <img src=\"test.gif\"> importhtml</body></html>",
                "c:\my picture", //test.gif is in c:\my picture
                ImportHtmlBodyOptions.ImportLocalPictures | ImportHtmlBodyOptions.ImportCss );

            Console.WriteLine("start to send email with embedded image...");
            oSmtp.SendMail(oServer, oMail);
            Console.WriteLine("email was sent successfully!");
        }
        catch (Exception ep)
        {
            Console.WriteLine("failed to send email with the following error:");
            Console.WriteLine(ep.Message);
        }
    }
}

}

下面的代码可以在邮件中发送多张图片

        string subject = "Subject";
        string body = @"Image 1: <img src='src1'/> <br/> Image 2: <img src='src2'/> <br/> Some Other Content";

        MailMessage mail = new MailMessage();
        mail.From = new MailAddress("<FromAddress@mail.com>");
        mail.To.Add(new MailAddress("<ToAddress@mail.com>"));
        mail.Subject = subject;
        mail.Body = body;
        mail.Priority = MailPriority.Normal;

        string contentID1 = Guid.NewGuid().ToString().Replace("-", "");
        string contentID2 = Guid.NewGuid().ToString().Replace("-", "");

        body = body.Replace("src1", "cid:" + contentID1);
        body = body.Replace("src2", "cid:" + contentID2);

        AlternateView htmlView = AlternateView.CreateAlternateViewFromString(body, null, "text/html");

        //path of image or stream
        LinkedResource imagelink1 = new LinkedResource(@"F:\Images0817045614.png", "image/png");
        imagelink1.ContentId = contentID1;
        imagelink1.TransferEncoding = System.Net.Mime.TransferEncoding.Base64;
        htmlView.LinkedResources.Add(imagelink1);

        LinkedResource imagelink2 = new LinkedResource(@"F:\Images0817045837.png", "image/png");
        imagelink2.ContentId = contentID2;
        imagelink2.TransferEncoding = System.Net.Mime.TransferEncoding.Base64;
        htmlView.LinkedResources.Add(imagelink2);

        mail.AlternateViews.Add(htmlView);

        using (SmtpClient smtpClient = new SmtpClient("<SMTPHostAddress>"))
        {
            smtpClient.Send(mail);
        }

希望这有效！！
