    {
        string filename = "~/Files/Mastering MeteorJS Application Development.pdf";
        String _fileName = "akash";
        string path = MapPath(filename);
        //byte[] bts = System.IO.File.ReadAllBytes(path);
        Response.Buffer = true;
        Response.ContentType = "application/pdf";
        Response.AddHeader("content-disposition:", "attachment;filename=" + _fileName + ".pdf");
        Response.TransmitFile(path);
        //Response.Close();
    }

There is a problem i faced when published the web application.This Files folder does not copy on Published folder on visual studio 2010 after publishing the app to file system.so i manually copy the Files directory with contents after published of web application and paste in that dir. now its ok
