C# iTextsharp Replace Page of a multi-page PDF -


say, have 5-page pdf called 'a.pdf' page 2 , 4 empty. , 2-page pdf called 'b.pdf'. want copy the first page of 'b.pdf' page2 of 'a.pdf' , second page of 'b.pdf' page 4 of 'a.pdf'.

i found it's quite hard find examples, found provided here, http://itextsharp.10939.n7.nabble.com/replace-pages-with-itextsharp-td2956.html called 'pdfstamper.replacepage()', guess i'm looking for, did simple demo didn't work out. can have check me?

string _outmergefile = server.mappath("~/11/a.pdf");  string file2 = server.mappath("~/11/b.pdf"); pdfreader readera = new pdfreader(_outmergefile); pdfreader readerb = new pdfreader(file2);  pdfstamper cc = new pdfstamper(readera,new memorystream());  cc.replacepage(readerb, 1, 2); cc.replacepage(readerb, 2, 4); cc.close();

thanks in advance.

================================================================================= jose's suggestion. code works now. i'm providing simple sample here others reference.

public void myfunction() {     string _outmergefile = server.mappath("~/11/a.pdf");      string file2 = server.mappath("~/11/b.pdf");     pdfreader readera = new pdfreader(_outmergefile);     pdfreader readerb = new pdfreader(file2);      pdfstamper cc = new pdfstamper(readera, new filestream(server.mappath("~/11/result.pdf"), filemode.append));      cc.replacepage(readerb, 1, 2);     cc.close(); }

ok, think i've found problem. cc created in memory, , don't see code save actual changes file before close it, alterations made in-memory file lost. 1 option create new filestream () instead of memory stream
