ASP.NET MVC 4 FileResult - In error

Question

I have a simple Action on a controller which returns a PDF.

Works fine.

public FileResult GetReport(string id)
{
    byte[] fileBytes = _manager.GetRepor         


        

Answer 1

The FileResult class inherits from ActionResult. So, you can define your Action like this:

public ActionResult GetReport(string id)
{
    byte[] fileBytes = _manager.GetReport(id);
    string fileName = id + ".pdf";

    if(fileBytes == null || fileBytes.Length == 0)
       return View("Error");

    return File(fileBytes, MediaTypeNames.Application.Octet, fileName);
}
