我正在尝试将 MS 图表放入 outlook 电子邮件中。我想避免将它保存到桌面上，所以我决定使用 MemoryStream。到目前为止，这是我放在一起的:
MemoryStream s = new MemoryStream();
chart1.SaveImage(s, ChartImageFormat.Png);
s.Position = 0;
OutlookApp outlookApp = new OutlookApp();
MailItem mailItem = outlookApp.CreateItem(OlItemType.olMailItem);
mailItem.Subject = "This is the subject";
chart1.SaveImage(s, ChartImageFormat.Png);
chart1.SaveImage(s, ChartImageFormat.Png);
mailItem.HTMLBody = "<html><body>This is the <strong>funky</strong> message body</body></html>" ;
mailItem.Attachments.Add(s);
//Set a high priority to the message
mailItem.Importance = OlImportance.olImportanceHigh;
mailItem.To = "testemail@gmail.com";
mailItem.Display(false);
//mailItem.Send();
我似乎无法找到将 MemoryStream 放入电子邮件的方法。
请您参考如下方法:
Outlook 支持使用 SMTP 发送电子邮件。所以你可以使用 SmtpClient发送电子邮件。然后您可以将图片作为附件发送或将图片放在电子邮件正文中:
var body = @"Here is the chart: <br/> <img src=""$CONTENTID1$""/>";
var CONTENTID1 = Guid.NewGuid().ToString().Replace("-", "");
body = body.Replace("$CONTENTID1$", "cid:" + CONTENTID1);
var htmlView = AlternateView.CreateAlternateViewFromString(body, null, "text/html");
var stream = new MemoryStream();
this.chart1.SaveImage(stream, System.Drawing.Imaging.ImageFormat.Png);
stream.Position = 0;
LinkedResource imagelink1 = new LinkedResource(stream, "image/png");
imagelink1.ContentId = CONTENTID1;
imagelink1.TransferEncoding = System.Net.Mime.TransferEncoding.Base64;
htmlView.LinkedResources.Add(imagelink1);
MailMessage mail = new MailMessage();
mail.From = new MailAddress("someone@outlook.com");
mail.To.Add(new MailAddress("someone@example.com"));
mail.Subject = "Subject";
mail.AlternateViews.Add(htmlView);
SmtpClient client = new SmtpClient();
client.Host = "smtp-mail.outlook.com";
client.Port = 587;
client.EnableSsl = true;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = new NetworkCredential("someone@outlook.com", "password");
client.Send(mail);
这样，图表图像将显示在电子邮件正文中:
