推荐答案

你不能......你要做的就是创建一个新的pdf并将其与旧的pdf合并。但这并不复杂。看一下Stackoverflow上的这篇文章：

You cant.. What you have to do is create a new pdf and merge it with the old one. But it's not complicated. Have a look at this post at Stackoverflow:

http://stackoverflow.com/questions/566899/is-there-a-straight-forward-way-to-append-one-pdf-doc-to-another-using-itextshar[^]

尝试：

Try:

Document doc = new Document( PageSize.A4, 50, 50, 50, 50 );
PdfWriter writer = PdfWriter.GetInstance( doc, new FileStream("test.pfd", FileMode.OpenOrCreate) );
doc.AddDocListener( writer );
doc.Open();

doc.Add( new Chunk("chunk", "This chunk a new text!"));
doc.Close();
