Convert .doc to .docx using C# [closed]

问题:

I convert PDF file to the word file using PDFFocus.net dll. But for my system I want .docx file. I tried different ways. There some libraries available. But those are not free. This is my pdf to doc convert code.

    Using System;     Using System.Collections.Generic;     Using System.Linq;     Using System.Text;     Using System.Threading.Tasks;     Using iTextSharp.text;     Using iTextSharp.text.pdf;      namespace ConsoleApplication     {           class Program           {                static void main(String[] args)                {                     SautinSoft.PdfFocus f=new SautinSoft.PdfFocus();                     f.OpenPdf(@"E:\input.pdf");                           t.ToWord(@"E:\input.doc");                 }           }     } 

This work successfully. Then I tried with below code to convert .doc to .docx. But it gives me error.

//Open a Document. Document doc=new Document("input.doc"); //Save Document. doc.save("output.docx"); 

Can anyone help me please.

Yes like Erop said. You can use the Microsoft Word 14.0 Object Library. Then it's really easy to convert from doc to docx. E.g with a function like this:

    public void ConvertDocToDocx(string path)     {         Application word = new Application();          if (path.ToLower().EndsWith(".doc"))         {             var sourceFile = new FileInfo(path);             var document = word.Documents.Open(sourceFile.FullName);              string newFileName = sourceFile.FullName.Replace(".doc", ".docx");             document.SaveAs2(newFileName,WdSaveFormat.wdFormatXMLDocument,                               CompatibilityMode: WdCompatibilityMode.wdWord2010);              word.ActiveDocument.Close();             word.Quit();              File.Delete(path);         }     } 

Make sure to add CompatibilityMode: WdCompatibilityMode.wdWord2010 otherwise the file will stay in compatibility mode. And also make sure that Microsoft Office is installed on the machine where you want to run the application.

Another thing, I don't know PDFFocus.net but have you tried converting directly from pdf to docx. Like this:

     static void main(String[] args)      {            SautinSoft.PdfFocus f=new SautinSoft.PdfFocus();            f.OpenPdf(@"E:\input.pdf");                  t.ToWord(@"E:\input.docx");      } 

I would assume that this is working, but it's only an assumption.

Try to use Microsoft.Office.Interop.Word assembly.

An MSDN article can be found Here

Include references in your project, and enable their use in a code module via an example from the above link that shows

using System.Collections.Generic; using Word = Microsoft.Office.Interop.Word;
