Creating the instance of PdfDocument:

 

             PdfDocument document_doc = new PdfDocument();  

 

Load the file location, in this code “spire.pdf” is a PDF file as in the following:

 

            document_doc.LoadFromFile(@"E:\MVC APP\SpireDoc\SpireDoc\spire.pdf");  

 

Convert the PDF file into Document format using “FileFormat.Doc” as in the following:

 

            document_doc.SaveToFile("Spire.doc", FileFormat.DOC);  

 

Launch the conversion process as in the following:

 

           System.Diagnostics.Process.Start("Spire.doc");  

 

Examples

 

The following converts a PDF to Xps:

//Creating instance of PdfDocument

PdfDocument document = new PdfDocument();

//Loading the File path of pdf file

document.LoadFromFile(@"E:\MVC APP\SpireDoc\SpireDoc\SpireXps.pdf");

//Save Spire.Pdf.PdfDocument object as XPS format.

document.SaveToFile("SpireXps.xps", FileFormat.XPS);

//Launch XPS

System.Diagnostics.Process.Start("SpireXps.xps");
