converting word to pdf using c#

Hi, if you have MS Word installed then you could use a Word automation in your C# application, for example like the following:

using Microsoft.Office.Interop.Word;

var application = new Application();
var document = application.Documents.Open(FileName: @"C:\Sample.docx");
document.ExportAsFixedFormat(OutputFileName: @"C:\Sample.pdf",
                             ExportFormat: WdExportFormat.wdExportFormatPDF);
 
document.Close();
application.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject(application);

If not, than you can try combining an OpenXML SDK and iTextSharp, I tried this once but unfortunately the result was not satisfying.
You can also try this Word component in C#, I used it in quite a few scenarios and tasks that required a DOCX manipulations in .NET and I must say it is easy to work with.
For example here is a direct way you can convert your Word document into a PDF file in .NET:

DocumentModel.Load(@"C:\Sample.docx", LoadOptions.DocxDefault)
             .Save(@"C:\Sample.pdf", SaveOptions.PdfDefault);

1. Declare a document and load document which you prepare by using ocument.LoadFromFile() method. The parameter passed to this method is file name string.
2. Save Word document as PDF by using document.SaveToFile() method. Parameters passed to this method is file name string and file format. The file format must be PDF.
You can download spire.DOC here :http://netword.codeplex.com/

C#

using System;

 using Spire.Doc;

 using Spire.Doc.Documents; namespace DoctoPDF

 {

 class toPDF

 {

 static void Main(string[] args)


 { //Load Document

 Document document = new Document();

 document.LoadFromFile(@"E:\work\documents\TestSample.docx");

 //Convert Word to PDF

 document.SaveToFile("toPDF.PDF", FileFormat.PDF);

 //Launch Document

 System.Diagnostics.Process.Start("toPDF.PDF");

 }

 }

 }




{Visual Basic]

Imports System

 Imports Spire.Doc

 Imports Spire.Doc.Documents

 Namespace DoctoPDF

 Friend Class toPDF

 Shared Sub Main(ByVal args() As String)


 'Load Document

 Dim document As New Document()

 document.LoadFromFile("E:\work\documents\TestSample.docx")

 'Convert Word to PDF

 document.SaveToFile("toPDF.PDF", FileFormat.PDF)

 'Launch Document

 System.Diagnostics.Process.Start("toPDF.PDF")

 End Sub

 End Class

 End Namespace
