I'd done something similar what you want on MVC 5 and I used FilePathResult as J.W said.

cshtml:

@Html.ActionLink("Download Here", "DownloadExampleFiles", "Product", new { fileName = "variation-example" }, new { @target = "_blank" })

ProductController:

public FilePathResult DownloadExampleFiles(string fileName)
{
    return new FilePathResult(string.Format(@"~\Files\{0}", fileName + ".txt"), "text/plain");
}

Download a file seems to be very silly/easy, however, for those who are new on MVC, it's not. This approach sounds to be the best while using MVC.

PS: I've forced a .txt just as an example. You should do what is intersting for you to get the specific file.

Check out this tutorial to return different action result.

The ASP.NET MVC framework supports several types of action results including:

  • ViewResult – Represents HTML and markup.
  • EmptyResult – Represents no result.
  • RedirectResult – Represents a redirection to a new URL.
  • JsonResult – Represents a JavaScript Object Notation result that can be used in an AJAX application.
  • JavaScriptResult – Represents a JavaScript script.
  • ContentResult – Represents a text result.
  • FileContentResult – Represents a downloadable file (with the binary content).
  • FilePathResult – Represents a downloadable file (with a path).
  • FileStreamResult – Represents a downloadable file (with a file stream).

Something like this maybe:

<h2>List Of Reports</h2>
<ul>
    <% foreach (var report in Model){ %>
        <li><a href="<%= Html.BuildUrlFromExpression<ReportController>(r => r.Reports(report.Filename)) %>"><%=report.Filename %></a></li>
    <% } %>
</ul>

There maybe a shorter way but this works.

AFAIK, there is nothing special about doing this in MVC. Create a LinkButton on your form with a handler that generates the PDF file, then redirect to the created file.
