convert doc to pdf in c#

问题

How can i convert .doc to .pdf using asp.net c#. I cannot use any third party component.

The code should be in

C# or vb.net
Compatible with VS 2005. (If not, then also please post your replies, i would then manually convert to VS 2005)

Let me know if any query.

Thanks!

Prerequisites:

MS word2007 with (Primary Interoperability assembly will be installed by default).
plugin SaveAsPDFandXPS (free from MS Site)

Make sure you have reference to Word.12. It will automatically add Microsoft.Office.interop.word to your reference. Follow these for other office application. (Note: you should have installed VS 2005 Tools for Office 2nd Ed. Runtime (VSTO 2005 SE) (x86)

//Add Office Library

using Word = Microsoft.Office.Interop.Word;

object str_letter_path = @"D:\DOCTEST.doc";
object outputFilePathPDF = @"D:\PDFTEST.PDF";

Word.Application wordApp = new Word.Application();
wordApp.Visible = false;
wordApp.ScreenUpdating = false;

object oMissing = System.Reflection.Missing.Value;
object fileFormat = Word.WdSaveFormat.wdFormatPDF;

Word.Document doc = wordApp.Documents.Open(ref str_letter_path, ref oMissing,
                ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
                ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing,
                ref oMissing, ref oMissing, ref oMissing, ref oMissing);

            doc.Activate();

            doc.SaveAs(ref outputFilePathPDF,
                            ref fileFormat, ref oMissing, ref oMissing,
                            ref oMissing, ref oMissing, ref oMissing, ref oMissing,
                            ref oMissing, ref oMissing, ref oMissing, ref oMissing,
                            ref oMissing, ref oMissing, ref oMissing, ref oMissing);

            object saveChanges = Word.WdSaveOptions.wdDoNotSaveChanges;
            if (doc != null)
                ((Word._Document)doc).Close(ref saveChanges, ref oMissing, ref oMissing);
            ((Microsoft.Office.Interop.Word._Application)wordApp).Quit(ref saveChanges, ref oMissing, ref oMissing);

You can use Microsoft.Office.Interop.Word.dll to convert Word file to PDF.

Install the package first and add a reference to it.

using Microsoft.Office.Interop.Word;

Then use the following code to Convert word document to PDF.

Application app = new Application();
Document doc = app.Documents.Open(@"D:/test.docx");
doc.SaveAs2(@"D:/test.pdf", WdSaveFormat.wdFormatPDF);
doc.Close();
app.Quit();
Console.WriteLine("Completed");
