今天遇到了，需要将pdf文件插到word里，好像word不支持直接插入pdf文件，所以现在通过将pdf转为图片的方式，逐个将图片插入到word。这里使用apose.pdf第三方库，将多个pdf文件读取，然后转为pdf。具体的实现代码如下所示。

 private void BTN_PDF_TO_IMAGES_Click(object sender, EventArgs e){List<string> files = GetFiles(@"C:\Users\qrb\Desktop\测绘资质\三、专业技术人员\part7", new string[] { "*.pdf"});int indexxx = 0;foreach (var item in files){indexxx = indexxx + 1;Console.WriteLine(item);try{Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document(item);int pageCount = pdfDocument.Pages.Count;Aspose.Pdf.Devices.Resolution resolution = new Aspose.Pdf.Devices.Resolution(130);Aspose.Pdf.Devices.JpegDevice jpegDevice = new Aspose.Pdf.Devices.JpegDevice(resolution);string parentPath=Path.GetDirectoryName(item);string fileNameWithoutExtension = Path.GetFileNameWithoutExtension(item);for (int pageIndex = 1; pageIndex <= pageCount; pageIndex++) {string fileName = parentPath + "\\"+ fileNameWithoutExtension + "_" + Convert.ToString(pageIndex)+".jpeg";MemoryStream stream = new MemoryStream();jpegDevice.Process(pdfDocument.Pages[pageIndex], stream);using (var fs = new FileStream(fileName, FileMode.OpenOrCreate)){jpegDevice.Process(pdfDocument.Pages[pageIndex], fs);fs.Close();}}}catch (Exception ex) {System.Windows.Forms.MessageBox.Show("异常错误:" + ex.ToString());}}
