How to Show pdf file in C#

We know that PDF is not Microsoft technology, it is created by Adobe system and widely used for document exchange, and based on post script. .Net framework does not provide any library to handles PDF files or it is not easy to handle PDF files in .net.

If we want to show PDF file in .net windows form than we can use many approaches such as we can use web browser control or we can use office library. But except these we can also use Acrobat reader control. Adobe provides an ActiveX COM control that you can add to the C# Toolbox.  It is free component provided by Adobe Acrobat.

Start C# Windows application and add the ‘Adobe PDF Reader’ control to the C# Toolbox.
Right-click on any tab of toolbox and select “Choose Items…’ Select the “COM Components” tab and check “Adobe PDF Reader” and click OK.

  2. That is very nice tutorial….Thanks a lot Mr…

    I think (dlg.Filter = “pdf files (*.pdf) |*.pdf;”;)
    line should be corrected like this…
    (dlg.Filter = “all files|*.pdf”;) or should be removed that bracket…

  4. What version of VS are you using. I’ve tried this with VS2005 & VS2010 with Reader X & XI respectively. The DLL isn’t there. Are you sure you don’t need the full Acrobat installed?

    1. The only Acrobat reader should installed on the machine..

      You can verify whether your machine has the DLL or not from the :

      C:Program Files (x86)Common FilesAdobeAcrobatActiveXAcroPDF.dll
