Generating HTML Email Body in C#

Generating HTML email body in C#

You can use the MailDefinition class.

This is how you use it:

MailDefinition md = new MailDefinition();
md.From = "test@domain.example";
md.IsBodyHtml = true;
md.Subject = "Test of MailDefinition";

ListDictionary replacements = new ListDictionary();
replacements.Add("{name}", "Martin");
replacements.Add("{country}", "Denmark");

string body = "<div>Hello {name} You're from {country}.</div>";

MailMessage msg = md.CreateMailMessage("you@anywhere.example", replacements, body, new System.Web.UI.Control());

Also, I've written a blog post on how to generate HTML e-mail body in C# using templates using the MailDefinition class.

Because there's no designation of IsBodyHTML set to true when using the Send function the way you've done. I think IsBodyHTML is within the MailMessage object.

I'm not entirely sure what IsBodyHTML sets in the body but it may create fully formed HTML (<html><head><body>etc....) so maybe give that a try.

How to send HTML-formatted email?

Setting isBodyHtml to true allows you to use HTML tags in the message body:

msg = new MailMessage("xxxx@gmail.com",
                "yyyy@gmail.com", "Message from PSSP System",
                "This email sent by the PSSP system<br />" +
                "<b>this is bold text!</b>");

msg.IsBodyHtml = true;

Can I set up HTML/Email Templates with ASP.NET?

There's a ton of answers already here, but I stumbled upon a great article about how to use Razor with email templating. Razor was pushed with ASP.NET MVC 3, but MVC is not required to use Razor. This is pretty slick processing of doing email templates

As the article identifies, "The best thing of Razor is that unlike its predecessor(webforms) it is not tied with the web environment, we can easily host it outside the web and use it as template engine for various purpose. "
