奇威羊的程式甜甜圈

下面為使用iTextSharp來合併PDF檔的function

using iTextSharp.text; using iTextSharp.text.pdf; using System.IO; using System.Collections; using System.ComponentModel; using System.Text; /// <summary> 合併PDF檔(集合) </summary> /// <param name="fileList">欲合併PDF檔之集合(一筆以上)</param> /// <param name="outMergeFile">合併後的檔名</param> private void mergePDFFiles(string[] fileList,string outMergeFile) { outMergeFile = Server.MapPath(outMergeFile); 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.Length;i++) { reader = new PdfReader(Server.MapPath(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); } } document.Close(); }

如要叫用可以用以下方式

private void mergePDF() { string[] pdflist = new string[3]; pdflist[0] = "RPT01.pdf"; pdflist[1] = "RPT02.pdf"; pdflist[2] = "RPT03.pdf"; mergePDFFiles(pdflist,"newpdf1.pdf"); }
