In controller you can use MvcHtmlString
public class HomeController : Controller
{
public ActionResult Index()
{
string rawHtml = "<HTML></HTML>";
ViewBag.EncodedHtml = MvcHtmlString.Create(rawHtml);
return View();
}
}
In your View you can simply use that dynamic property which you set in your Controller like below
<div>
@ViewBag.EncodedHtml
</div>
