Download part of html as a template in c# mvc?

Question

I have an MVC5 C# project and in one of the pages, i'm showing a list of HTML email templates so the user can see how the email templates are and be aware of what is being send to the customers. Now, what i want is a button in each template that allow me to download that template in one .html file. How is this possible?

Answer 1

Use

public ActionResult Index()
{
    var fc = System.IO.File.ReadAllBytes(Server.MapPath("~/Path/To/File.html");
    return File(fc, "application/octet-stream", "download file name.html");
}

This will change the way the client will process it and will assume it's a downloadable file.

Tested on IE11 and FF.

Finally i came with this solution:

public ActionResult DownloadTemplate(string templateName)
        {
            using (var service = new MyService())
            {
                var template = service.GetEmailTemplateByName(templateName);
                string attachment = string.Format("attachment; filename={0}_TEMPLATE.html", templateName);
                Response.ClearContent();
                Response.AddHeader("content-disposition", attachment);
                Response.ContentType = "text/html";
                Response.Write(template.Body);
                Response.End();
                return new EmptyResult();
            }
        }
