I have written below code to embed image in the mail which is being sent from my c# code. But when i check the mail, i get image like an attachment and not as an inline image. (Gmail)
AlternateView htmlBodyView = null;
string htmlBody = "<html><body><h1></h1><br><img src=\"cid:SampleImage\"></body></html>";
AlternateView plainTextView = AlternateView.CreateAlternateViewFromString(htmlBody, null, "text/html");
ImageConverter ic = new ImageConverter();
Byte[] ba = (Byte[])ic.ConvertTo(bitmap_obj, typeof(Byte[]));
using (MemoryStream logo = new MemoryStream(ba))
{
LinkedResource sampleImage = new LinkedResource(logo, "image/jpeg");
sampleImage.ContentId = "sampleImage";
htmlBodyView.LinkedResources.Add(sampleImage);
p.SendEmail(htmlBodyView);
}
For reference, a full working simplified example:
public void SendMail()
{
LinkedResource logo = new LinkedResource(
"images\\image005.png", //Path of file
"image/png"); //Mime type: Important!
logo.ContentId = "logo"; //ID for reference
//Actual HTML content of the body in an 'AlternateView' object.
AlternateView vw = AlternateView.CreateAlternateViewFromString(
"Hello, this is <b>HTML</b> mail with embedded image: <img src=\"cid:logo\" />",
null,
MediaTypeNames.Text.Html); //Mime type: again important!
vw.LinkedResources.Add(logo);
var msg = new MailMessage() { IsBodyHtml = true };
msg.AlternateViews.Add(vw);
msg.From = new MailAddress("sender#domain.com");
msg.To.Add(new MailAddress("reciever#domain.com"));
msg.Subject = "HTML Mail!";
using (var client = new SmtpClient("localhost", 25))
client.Send(msg);
}

I have a class that returns an Image:
public static Image GenerateVoucher(decimal voucherAmount, string voucherCode,
DateTime expiryDate)
{
...
Image img = Image.FromFile(path);
using (Graphics graphics = Graphics.FromImage(img))
{
...various drawing on the image...
graphics.DrawString(voucherAmount.ToString(), new Font(handleGothic.Families[0], 113), blueBrushColour, largeVoucherAmountLocation);
}
return img;
}
and I want to embed this response into an email:
public static MailMessage CreateImagedEmail(string mailTo, decimal voucherAmount, string voucherCode, DateTime expiryDate)
{
var mail = new MailMessage();
mail.From = new MailAddress("fromaddress.com");
mail.To.Add(mailTo);
mail.Subject = "Your Email with an image inline";
var plainView = AlternateView.CreateAlternateViewFromString(
"Your email client has detected it is unable to render html emails...",
null, "text/plain");
var htmlView = AlternateView.CreateAlternateViewFromString(
"<h1>Some HTML message </h1>" +
"<img src=cid:voucher>",
null, "text/html");
var voucher = GenerateVoucher(voucherAmount, voucherCode, expiryDate);
LinkedResource voucherImg = new LinkedResource(path);
voucherImg.ContentId = "voucher";
htmlView.LinkedResources.Add(voucherImg);
mail.AlternateViews.Add(plainView);
mail.AlternateViews.Add(htmlView);
return mail;
}
This works fine in the example above when returning the image from the file system, but when I try and add the Image from the method above the LinkedResources complains that it is not a string. I'm happy to convert it to a stream if that will work
I am using following code to send email but it is failed if I used html attachment.
System.IO.MemoryStream ms = new System.IO.MemoryStream();
System.IO.StreamWriter writer2 = new System.IO.StreamWriter(ms);
writer2.Write("<html><head></head><body>Invoice 1</body></html>");
writer2.Flush();
writer2.Dispose();
MailMessage mm = new MailMessage();
mm.To.Add("test#gmail.com");
mm.CC.Add("test2#gmail.com");
mm.From = new MailAddress("test3#gmail.com");
mm.Subject = "नोटिस";
mm.Body = sb.ToString();
System.Net.Mime.ContentType ct = new System.Net.Mime.ContentType(System.Net.Mime.MediaTypeNames.Text.Html);
System.Net.Mail.Attachment attach = new System.Net.Mail.Attachment(ms, ct);
attach.ContentDisposition.FileName = "myFile.html";
mm.Attachments.Add(attach);
mm.Attachments.Add(new Attachment(new MemoryStream(bytes), "rcms.pdf"));
ms.Close();
mm.IsBodyHtml = true;
only one line needed.
var a = System.Net.Mail.Attachment.CreateAttachmentFromString("'"+sb.ToString()+"'</body>", "notices.html");
I encrypted an image,
Now I need to read that image, decrypt and attach it into an email.
For first step I try to put an image file and attach it into an Email,
but when i receive email, the attached image is corrupted !
I try many different ways, but without success.
(I created windows application project just for test, Eventually I need to use solution in MVC Web Application project)
private void btnSend_Click(object sender, EventArgs e)
{
var filePath = "D:\\3.jpg"; // path to none encrypted image file
var ms = new MemoryStream(File.ReadAllBytes(filePath));
// Create attachment
var attach = new Attachment(ms, new ContentType(MediaTypeNames.Image.Jpeg));
attach.ContentDisposition.FileName = "sample.jpg";
// Send Email
IMailSender mailSender = new MailSender();
var isSuccess = mailSender.Send(
"sample email title",
"sample#gmail.com",
"sample subject",
"sample body",
new Attachment[] { attach });
MessageBox.Show(isSuccess ? "Email sent successfully" : mailSender.ErrorMessage);
}
using (MailMessage Message = new MailMessage())
{
Message.From = new MailAddress("from#mail.com");
Message.Subject = "My Subject";
Message.Body = "My Body";
Message.To.Add(new MailAddress("to#mail.com"));
//Attach more file
foreach (var item in Attachment)
{
MemoryStream ms = new MemoryStream(File.ReadAllBytes(filePath));
Attachment Data = new Attachment(ms, "FileName");
ContentDisposition Disposition = Data.ContentDisposition;
Disposition.CreationDate = DateTime.UtcNow.AddHours(-5);
Disposition.ModificationDate = DateTime.UtcNow.AddHours(-5);
Disposition.ReadDate = DateTime.UtcNow.AddHours(-5);
Data.ContentType = new ContentType(MediaTypeNames.Application.Pdf);
Message.Attachments.Add(Data);
}
SmtpClient smtp = new SmtpClient("SmtpAddress", "SmtpPort");
smtp.Credentials = new NetworkCredential("SmtpUser", "SmtpPassword");
await smtp.SendMailAsync(Message);
}
I hope this helps
I'm trying to insert an image in an email following this http://www.codeproject.com/Tips/326346/How-to-embed-a-image-in-email-body
but for some images are not showing in the mail.
Here is the code.
var message = new MailMessage();
message.From = new MailAddress("noreply#happy.com");
message.To.Add("testmail#gmail.com");
var body = new StringBuilder();
message.IsBodyHtml = true;
message.BodyEncoding = Encoding.UTF8;
var path = #"C:\Users\Public\Pictures\Sample Pictures\Penguins.jpg";
AlternateView altView = AlternateView.CreateAlternateViewFromString("testing mail: <img src=cid:myImage>", null, MediaTypeNames.Text.Html);
LinkedResource imageToSend = new LinkedResource(path);
imageToSend.ContentId = "myImage";
altView.LinkedResources.Add(imageToSend);
message.AlternateViews.Add(altView);
var smtp = new SmtpClient();
smtp.Send(message);
How can I put this ==>
url('data:image/jpeg;base64,/9j/4AAQSkZJRgABAgEASABIAAD/2wBDAAEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEB') into new System.Net.Mail.LinkedResource()
to send mail form C#, using background css style with base64 string, not file url.
I wondered this myself and got to this post. I solved it and figured i would share the my solution.
var imageData = Convert.FromBase64String("/9j/4AAQSkZJRgABAgEASABIAAD/2wBDAAEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEB");
var contentId = Guid.NewGuid().ToString();
var linkedResource = new LinkedResource(new MemoryStream(imageData), "image/jpeg");
linkedResource.ContentId = contentId;
linkedResource.TransferEncoding = TransferEncoding.Base64;
var body = string.Format("<img src=\"cid:{0}\" />", contentId);
var htmlView = AlternateView.CreateAlternateViewFromString(body, null, "text/html");
htmlView.LinkedResources.Add(linkedResource);
