Not clear at all. How is that: "saving to pdf using asp.net but i am using win forms"?

It simply means he got some code working on server side in an ASP.NET project, and would like to use it in a Winforms application (thus, no Response object whatsoever) :)

Of course... :-)
Thank you, Phil.

You can use a stream other than a memory-one (for example, a binary file stream) and write to it.

This could look like:

C#

using (FileStream fs = File.Open("First_PDF_document.pdf"))
using(Document document = new Document(PageSize.A4, 25, 25, 30, 30))
using(PdfWriter writer = PdfWriter.GetInstance(document, fs))
{
    document.Open();
    document.Add(new Paragraph("Hello World"));
    document.Close();
    writer.Close();
    fs.Close();
}

This way you do not construct a Response object (relative to web connections), but rather an actual file on your filesystem.

Hope this helps.

PS: you may have to adapt the content of using blocks a little bit; I currently have no IDE installed on my computer, so unable to test for that piece of code.
