How the path should be when including images into MvCMailer Mail

Question

im trying to embed an image when sending an email with MvCMailer like this:

    Dictionary<string,string> resources = new Dictionary<string,string>();
    resources["logo"] = new Uri(new Uri(string.Format("{0}://{1}{2}", System.Web.HttpContext.Current.Request.Url.Scheme, System.Web.HttpContext.Current.Request.Url.Authority, Url.Content("~"))), "/Content/images/logo.png").ToString();
    mailSender.Confirm(user.Username, user.Email, link,resources).Send();

How ever it generate this:

URI formats are not supported.

Im not sure what kind of path i should send, and how to generate it ?

Answer 1

Resource paths should be local paths on disk, not URLs.

Write

resources["logo"] = Server.MapPath("~/Content/images/logo.png");
