ASP.NET MVC: render view to generate PDF: use iTextSharp or better solution?

If you can have the HTML in memory then you can convert it to PDF. I've once did something similar using xhtmlrenderer. It is a JAVA framework that bundles iText and that is capable of converting an HTML stream into PDF. As it is written in JAVA I've used the ikvmc.exe to convert the jar file into a .NET assembly and use it directly from managed code.

 public class Pdf : IPdf
    {
        public FileStreamResult Make(string s)
        {
            using (var ms = new MemoryStream())
            {
                using (var document = new Document())
                {
                    PdfWriter.GetInstance(document, ms);
                    document.Open();
                    using (var str = new StringReader(s))
                    {

                        var htmlWorker = new HTMLWorker(document);

                        htmlWorker.Parse(str);
                    }
                    document.Close();
                }

                HttpContext.Current.Response.ContentType = "application/pdf";
                HttpContext.Current.Response.AddHeader("content-disposition", "attachment;filename=MyPdfName.pdf");
                HttpContext.Current.Response.Buffer = true;
                HttpContext.Current.Response.Clear();
                HttpContext.Current.Response.OutputStream.Write(ms.GetBuffer(), 0, ms.GetBuffer().Length);
                HttpContext.Current.Response.OutputStream.Flush();
                HttpContext.Current.Response.End();

                return new FileStreamResult(HttpContext.Current.Response.OutputStream, "application/pdf");
            }
        }
    }
