        {

            PdfReader reader;

            Document document = new Document();

            PdfWriter writer = PdfWriter.GetInstance(document, new FileStream(outMergeFile, FileMode.Create));

            document.Open();

            PdfContentByte cb = writer.DirectContent;

            PdfImportedPage newPage;

            for (int i = 0; i < fileList.Count; i++)

            {

                reader = new PdfReader(fileList[i]);

                int iPageNum = reader.NumberOfPages;

                for (int j = 1; j <= iPageNum; j++)

                {

                    document.NewPage();

                    newPage = writer.GetImportedPage(reader, j);

                    cb.AddTemplate(newPage, 0, 0);

                }

            }

            if (print)

            {

                StringBuilder script = new StringBuilder();

                script.Append("this.print({bUI: true,bSilent: true,bShrinkToFit: false});");

                writer.ViewerPreferences = PdfWriter.HideMenubar | PdfWriter.HideToolbar | PdfWriter.HideWindowUI;

                writer.AddJavaScript(script.ToString());

                //PdfAction.JavaScript("myOnMessage();", writer);

                //writer.AddJavaScript("this.print(true);function myOnMessage(aMessage) {app.alert('Test',2);} var msgHandlerObject = new Object();doc.onWillPrint = myOnMessage;this.hostContainer.messageHandler = msgHandlerObject;");

            }

            document.Close();

        }

    }

}

调用函数：

 private const short PDSAVEFULL = 1;

 private void btnMerage_Click(object sender, EventArgs e)

 {

       string path = "C:\\Users\\Administrator\\Desktop\\PDFTest\\newpdf2.pdf";

       iTextSharp test = new iTextSharp();

       test.mergePDFFiles(FileList,path,true);

       System.Diagnostics.Process.Start(path);

 }

 List<string> FileList = new List<string>();

 private void btnSelectFolder_Click(object sender, EventArgs e)

 {

       folderBrowserDialog.ShowDialog();

       string floderpath = folderBrowserDialog.SelectedPath;

       if (string.IsNullOrEmpty(floderpath)) { MessageBox.Show("path error"); return; }

       DirectoryInfo theFolder = new DirectoryInfo(floderpath);

       FileInfo[] fileInfo = theFolder.GetFiles();

       foreach (FileInfo NextFile in fileInfo)  //遍历文件

       {

           FileList.Add(NextFile.FullName);

       }

 }
