ms word - How to programatically (C#) determine the pages count of .docx files

Question

I have about 400 files in .docx format, and I need to determine the length of each in #pages.

So, I want to write C# code for selecting the folder that contains the documents , and then returns the #pages of each .docx file.

Answer 1

To illustrate how this can be done, I have just created a C# console application based on .NET 4.5 and some of the Microsoft Office 2013 COM objects.

using System;
using Microsoft.Office.Interop.Word;

namespace WordDocStats
{
    class Program
    {
        // Based on: http://www.dotnetperls.com/word
        static void Main(string[] args)
        {
            // Open a doc file.
            var application = new Application();
            var document = application.Documents.Open(@"C:UsersMyNameDocumentsword.docx");

            // Get the page count.
            var numberOfPages = document.ComputeStatistics(WdStatistic.wdStatisticPages, false);

            // Print out the result.
            Console.WriteLine(String.Format("Total number of pages in document: {0}", numberOfPages));

            // Close word.
            application.Quit();
        }
    }
}

For this to work you need to reference the following COM objects:

• Microsoft Office Object Library (version 15.0 in my case)
• Microsoft Word Object Library (version 15.0 in my case)

The two COM objects gives you access to the namespaces needed.

For details on how to reference the correct assemblies, please refer to section: "3. Setting Up Work Environment:" at: http://www.c-sharpcorner.com/UploadFile/amrish_deep/WordAutomation05102007223934PM/WordAutomation.aspx

-- UPDATE

Documentation about the method Document.ComputeStatistics that gives you access to the page count can be found here: http://msdn.microsoft.com/en-us/library/microsoft.office.tools.word.document.computestatistics.aspx

As seen in the documentation, the method takes a WdStatistic enum that enables you to retrieve different kinds of stats, e.g., the total amount of pages. For an overview of the complete range of stats you have access to, please refer to the documentation of the WdStatistic enum, which can be found here: http://msdn.microsoft.com/en-us/library/microsoft.office.interop.word.wdstatistic.aspx
