How to retrieve a file from a database?

Question

ASP.NET

Good time!
I am writing an ASP.NET MVC net461 project.
I save an arbitrary file (.doc, .xls, etc.) in the MSSQL database. I store it as byte[]. But I can’t understand how I can download this file from the link on the client side? How to convert a byte array to a file?
Thanks in advance!

He who has hands, google it!

public ActionResult Index()
{
    byte[] contents = GetPdfFileData();
    return File(contents, "application/pdf", "test.pdf");
}
