How to save Rotativa PDF on server - asp.net-mvc-5

Question

I am using Rotativa to generate PDF in my "MVC" application. How can I save Rotativa PDF? I need to save the document on a server after all the process is completed.
Code below:
public ActionResult PRVRequestPdf(string refnum,string emid)
{
var prv = functions.getprvrequest(refnum, emid);
return View(prv);
}
public ActionResult PDFPRVRequest()
{
var prv = Session["PRV"] as PRVRequestModel;
byte[] pdfByteArray = Rotativa.WkhtmltopdfDriver.ConvertHtml("Rotativa", "Approver", "PRVRequestPdf");
return new Rotativa.ViewAsPdf("PRVRequestPdf", new { refnum = prv.rheader.request.Referenceno });
}

Answer 1

You can give this a try
var actionResult = new ActionAsPdf("PRVRequestPdf", new { refnum = prv.rheader.request.Referenceno, emid = "Whatever this is" });
var byteArray = actionResult.BuildPdf(ControllerContext);
var fileStream = new FileStream(fullPath, FileMode.Create, FileAccess.Write);
fileStream.Write(byteArray, 0, byteArray.Length);
fileStream.Close();
If that doesn't do the trick then, you can follow the answers here
Just make sure if you do it this way not to have PRVRequestPdf return as a PDF View, rather a normal View like you have above (only mention as managed to fall foul of that myself causing lots of fun).

Another useful answer:
I found the solution here
var actionPDF = new Rotativa.ActionAsPdf("YOUR_ACTION_Method", new { id = ID, lang = strLang } //some route values)
{
//FileName = "TestView.pdf",
PageSize = Size.A4,
PageOrientation = Rotativa.Options.Orientation.Landscape,
PageMargins = { Left = 1, Right = 1 }
};
byte[] applicationPDFData = actionPDF.BuildPdf(ControllerContext);
This is the original thread

You can achieve this with ViewAsPdf.
[HttpGet]
public ActionResult SaveAsPdf(string refnum, string emid)
{
try
{
var prv = functions.getprvrequest(refnum, emid);
ViewAsPdf pdf = new Rotativa.ViewAsPdf("PRVRequestPdf", prv)
{
FileName = "Test.pdf",
CustomSwitches = "--page-offset 0 --footer-center [page] --footer-font-size 8"
};
byte[] pdfData = pdf.BuildFile(ControllerContext);
string fullPath = #"\\server\network\path\pdfs\" + pdf.FileName;
using (var fileStream = new FileStream(fullPath, FileMode.Create, FileAccess.Write))
{
fileStream.Write(pdfData, 0, pdfData.Length);
}
return Json(new { isSuccessful = true }, JsonRequestBehavior.AllowGet);
}
catch (Exception ex)
{
//TODO: ADD LOGGING
return Json(new { isSuccessful = false, error = "Uh oh!" }, JsonRequestBehavior.AllowGet);
//throw;
}
}

You can simply try this:
var fileName = string.Format("my_file_{0}.pdf", id);
var path = Server.MapPath("~/App_Data/" + fileName);
System.IO.File.WriteAllBytes(path, pdfByteArray );
