Send HTML E-mails with embedded image content using ASP.NET C#
To send emails with HTML formatting and to embed resources such as
images, in csharp, we create an alternateview to hold the embedded
resource link and then create a linked resource object for each embedded
image. The content ID of the linked resource is used to embed the image
in the html email. add the HTML-tagged content to the Mail Body. The
important thing to remember is to set the IsBodyHtml attribute to True
on the mail object.
