Examples

The following example shows how to embed objects using LinkedResource into an Email.

[C#]

var eml = new MailMessage
{
	From = "[e-mail]",
	To = "[e-mail]",
	Subject = "This is an email"
};

// Create the plain text part It is viewable by those clients that don't support HTML
var plainView =
	AlternateView.CreateAlternateViewFromString("This is my plain text content", null, "text/plain");

// Create the HTML part.To embed images, we need to use the prefix 'cid' in the img src value.
// The cid value will map to the Content-Id of a Linked resource. Thus <img src='cid:barcode'>
// will map to a LinkedResource with a ContentId of 'barcode'.
var htmlView =
	AlternateView.CreateAlternateViewFromString("Here is an embedded image.<img src=cid:barcode>", null,
		"text/html");

// Create the LinkedResource (embedded image) and Add the LinkedResource to the appropriate view
var barcode = new LinkedResource("1.jpg", MediaTypeNames.Image.Jpeg)
{
	ContentId = "barcode"
};

eml.LinkedResources.Add(barcode);
eml.AlternateViews.Add(plainView);
eml.AlternateViews.Add(htmlView);

eml.Save("EmbeddedImage_out.msg", SaveOptions.DefaultMsgUnicode);

[Visual Basic]

Dim eml = New MailMessage With {
.From = "[e-mail]",
.[To] = "[e-mail]",
.Subject = "This is an email"
}

' Create the plain text part It is viewable by those clients that don't support HTML
Dim plainView = AlternateView.CreateAlternateViewFromString("This is my plain text content", Nothing, "text/plain")

' Create the HTML part.To embed images, we need to use the prefix 'cid' in the img src value.
' The cid value will map to the Content-Id of a Linked resource. Thus <img src='cid:barcode'>
' will map to a LinkedResource with a ContentId of 'barcode'.
Dim htmlView = AlternateView.CreateAlternateViewFromString("Here is an embedded image.<img src=cid:barcode>", Nothing, "text/html")

' Create the LinkedResource (embedded image) and Add the LinkedResource to the appropriate view
Dim barcode = New LinkedResource("1.jpg", MediaTypeNames.Image.Jpeg) With {
  .ContentId = "barcode"
		}

eml.LinkedResources.Add(barcode)
eml.AlternateViews.Add(plainView)
eml.AlternateViews.Add(htmlView)

eml.Save("EmbeddedImage_out.msg", SaveOptions.DefaultMsgUnicode)
