我正在构建一个修改单词2010文档的应用程序,它应该以pdf格式下载。我编写一个代码将单词转换为pdf,但它正在转换我上传的文档而不是修改后的单词。如何将修改后的单词转换为PDF.Below是不转换修饰单词的功能。 protected void btnUpload_Click(object sender,EventArgs e) {
if (FileUploadControl.HasFile)
{
string fileNameFromUser = FileUploadControl.FileName;
var fiFileName = new System.IO.FileInfo(fileNameFromUser);
using (MemoryStream ms = new MemoryStream())
{
ms.Write(FileUploadControl.FileBytes, 0, FileUploadControl.FileBytes.Length);
using (WordprocessingDocument sDoc = WordprocessingDocument.Open(ms, true))
{
}
lblMessage.Text = "Dokumenti u ngarkua me sukses!";
Session["ByteArray"] = FileUploadControl.FileBytes;
Session["fileNameFromUser"] = fileNameFromUser;
}
}
byte[] byteArray = (byte[])(Session["ByteArray"]);
if (byteArray != null)
{
try
{
using (MemoryStream ms = new MemoryStream())
{
ms.Write(byteArray, 0, byteArray.Length);
using (WordprocessingDocument wDoc = WordprocessingDocument.Open(ms, true))
{
var body = wDoc.MainDocumentPart.Document.Body;
var lastParagraf = body.Elements<Paragraph>().LastOrDefault();
var newParagraf = new Paragraph(
new Run(
new Text("Perdoruesi:" + " " + User.Identity.Name)));
var newParagraf2 = new Paragraph(
new Run(
new Text("Data dhe ora:" + " " + DateTime.Now.ToString())));
var newParagraf3 = new Paragraph(
new Run(
new Text("Kodi unik:" + " " + randomstring(14))));
var newParagraf4 = new Paragraph(
new Run(
new Text("Shifra:" )));
lastParagraf.InsertAfterSelf(newParagraf);
lastParagraf.InsertAfterSelf(newParagraf2);
lastParagraf.InsertAfterSelf(newParagraf3);
lastParagraf.InsertAfterSelf(newParagraf4);
}
Session["ByteArray"] = ms.ToArray();
lblMessage.Text = "U ngarkua dhe u vulos dokumenti!";
Guid pdfFileGuid = Guid.NewGuid();
var filePath = Path.GetTempFileName();
FileUploadControl.SaveAs(filePath);
var appWord = new Microsoft.Office.Interop.Word.Application();
var wordDoc = appWord.Documents.Open(filePath);
var convertedFilePath = Path.GetTempFileName();
wordDoc.ExportAsFixedFormat(convertedFilePath, Microsoft.Office.Interop.Word.WdExportFormat.wdExportFormatPDF);
Response.Clear();
Response.AddHeader("content-disposition", "attachment; filename=Converted.Pdf");
Response.AddHeader("content-type", "application/pdf");
Response.TransmitFile(convertedFilePath);
File.Delete(filePath);
File.Delete(convertedFilePath);
}
}
catch (Exception ex)
{
lblMessage.Text = "ERROR:" + ex.Message.ToString();
}
}
else
{
lblMessage.Text = "Nuk e keni zgjedhur dokumentin apo formati i dokumentit nuk pershtatet!";
}
}
答案 0 :(得分:0)
目前,您可以在此处将int pageCountBefore = builder.Document.PageCount;
中的数据加载到会话中:
FileUploadControl
然后,您将会话中的数据加载到用于打开文档进行编辑的Session["ByteArray"] = FileUploadControl.FileBytes;
中:
MemoryStream
在编辑结束时,您将更新的内容复制回会话:
byte[] byteArray = (byte[])(Session["ByteArray"]);
if (byteArray != null)
{
try
{
using (MemoryStream ms = new MemoryStream())
{
ms.Write(byteArray, 0, byteArray.Length);
using (WordprocessingDocument wDoc = WordprocessingDocument.Open(ms, true))
但;这是我们最后一次看到会话使用的时间;然后将上传的文件写入临时文件,并使用 执行Word自动化:
lastParagraf.InsertAfterSelf(newParagraf3);
lastParagraf.InsertAfterSelf(newParagraf4);
}
Session["ByteArray"] = ms.ToArray();
是的:这会将原始文件转换为上传,因为var filePath = Path.GetTempFileName();
FileUploadControl.SaveAs(filePath);
var appWord = new Microsoft.Office.Interop.Word.Application();
var wordDoc = appWord.Documents.Open(filePath);
与您所做的更改无关。相反,也许尝试:
FileUploadControl
然后应该包括更改。
补充侧面观察:
var filePath = Path.GetTempFileName();
File.WriteAllBytes(filePath, (byte[])Session["ByteArray"]);
var appWord = new Microsoft.Office.Interop.Word.Application();
var wordDoc = appWord.Documents.Open(filePath);
,appWord
,wordDoc
,filePath
等 - 所有可能都需要一些convertedFilePath
爱)finally
)可能是并不是一个好主意或必要的想法;我建议您在此方法中使用本地Session
或类似内容,并完全删除byte[]
