Question

我有一个将pdf文件合并在一起的桌面应用程序。我的老板希望我让应用程序将excel文件转换为pdf，并允许应用程序将它们全部合并在一起。有人可以帮忙吗？除了将excel文件转换为pdf的功能之外，我拥有一切，以便我可以成功地将它们转换。

我不确定itextsharp是否允许我将excel转换为pdf并将它们合并在一起，但是请让我知道我能做什么。

namespace mergePdf
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }


        protected void btnMerge_Click(object sender, EventArgs e)
        {


            if (!Directory.Exists(@"C:\Merge Folder\"))
                Directory.CreateDirectory(@"C:\Merge Folder\");
            Stream myStream;
            SaveFileDialog saveFileDialog1 = new SaveFileDialog();

            saveFileDialog1.Title = "Select PDFFile";
            saveFileDialog1.Filter = "PDF(*.pdf)|*.pdf";
            saveFileDialog1.FilterIndex = 2;
            saveFileDialog1.RestoreDirectory = true;

            if (saveFileDialog1.ShowDialog() == DialogResult.OK)
            {
                if ((myStream = saveFileDialog1.OpenFile()) != null)
                {
                    // Code to write the stream goes here.
                    myStream.Close();
                }
            }
            string pdfFile1 = Path.GetFullPath(textBoxPdfFile1Path.Text);
            string[] filenames = { pdfFile1 };
            string outputFileName = System.IO.Path.GetRandomFileName() + 
            ".pdf"; ;
            string outputPath = saveFileDialog1.FileName;

            FileInfo fileInfo = new FileInfo(outputPath);
            Console.WriteLine(fileInfo.DirectoryName);


            Document doc = new Document();
            PdfCopy writer = new PdfCopy(doc, new FileStream(outputPath, 
            FileMode.Create));
            if (writer == null)
            {
                return;
            }
            doc.Open();
            foreach (var filename in listBox1.Items)
            {
                PdfReader reader = new PdfReader(filename.ToString());
                reader.ConsolidateNamedDestinations();
                for (int i = 1; i <= reader.NumberOfPages; i++)
                {
                    PdfImportedPage page = writer.GetImportedPage(reader, i);
                    writer.AddPage(page);
                }

                reader.Close();
            }

            writer.Close();
            doc.Close();
            System.Diagnostics.Process.Start(outputPath);
        }



        private void Form1_Load(object sender, EventArgs e)
        {


        }

        protected void btnSelectFile1_Click(object sender, EventArgs e)
        {

            OpenFileDialog ofd = new OpenFileDialog();
            ofd.Filter = "PDF files (*.pdf)|*.pdf|All files (*.*)|*.*";
            ofd.Multiselect = true;

            if (ofd.ShowDialog() == DialogResult.OK)
            {
                textBoxPdfFile1Path.Text = ofd.FileName;
                string[] files = ofd.FileNames;
                listBox1.Items.AddRange(files);
            }
        }
    }
}
