How to detect all PDF Portfolio files in a directory?

[[email protected]]

I'm trying to find all of the files in a directory that are PDF Portfolio files. I found this code

Code: Select all

using System;
using Spire.Pdf;

namespace Detect_if_a_PDF_is_a_Portfolio
{
    class Program
    {
        static void Main(string[] args)
        {
            PdfDocument pdf = new PdfDocument();
            const string Filename = @"file path";
            pdf.LoadFromFile(Filename);

            bool isPortfolio = pdf.IsPortfolio;
            if (isPortfolio)
            {
                Console.WriteLine("It's a Portfolio!");
            }
            Console.Read();
        }
    }
}


and it works for a single file but I need to scan through an entire directory. Also, I'd like to change the console output from "It's a portfolio" to "path to file and name of file is a portfolio". Any help is appreciated as I really don't know much of anything about C#.

Hi,

Thanks for your inquiry.
Please refer to below code to load files from a directory. If there is any question, welcome to write back.

Code: Select all

string directory = "C:\\folder";
DirectoryInfo directoryInfo = new DirectoryInfo(directory);
FileInfo[] directoryFiles = directoryInfo.GetFiles();
foreach (FileInfo file in directoryFiles)
{
    PdfDocument pdf = new PdfDocument();
    pdf.LoadFromFile(file.FullName);
    bool isPortfolio = pdf.IsPortfolio;
    if (isPortfolio)
    {
        Console.WriteLine(file.FullName + " is a Portfolio!");
    }
}

Nina, thanks so much! This is awesome and is working. One thing, how could I exclude running this against pdf files that are secured? That seems to throw an exception stating the password is incorrect. I'm currently using the below to only include .PDF files and to include sub-directories. Can I add something to the search pattern to exclude secured pdf files?

Code: Select all

FileInfo[] directoryFiles = directoryInfo.GetFiles("*.pdf", SearchOption.AllDirectories);

Dear Mike,

Thanks for your feedback and sorry for late reply as weekend.
You could add try catch statement to exclude the Pdf files which have open password. Sample code is as follows. Any question, welcome to write back.

Code: Select all

foreach (FileInfo file in directoryFiles)
{
    PdfDocument pdf = new PdfDocument();
    try
    {
        pdf.LoadFromFile(file.FullName);
    }
    catch(Exception exception)
    {
        Console.WriteLine("The error of loading "+file.FullName +" is: "+ exception.Message);
        //Skip the current loop and force the next loop
        continue;
    }
    bool isPortfolio = pdf.IsPortfolio;
    if (isPortfolio)
    {
        Console.WriteLine(file.FullName + " is a Portfolio!");
    }
}

Nina, you have no idea how much of a headache you have saved me from. THANK YOU! This is working great. The only other question I had was if it is possible to output the console information to a .txt file? I tried

Code: Select all

               {
                    Console.WriteLine(file.FullName + " is a Portfolio!");
                }
           
        }
            File.WriteAllLines(@"c:\data.txt");
        }

But I can't seem to get the syntax right. No rush on this as what you have already given me is working pretty good. Again, I really appreciate your help.

Dear Mike,

Thanks for your feedback.
Please refer to the following code to write the information in a .txt file.

Code: Select all

StringBuilder builder = new StringBuilder();
foreach (FileInfo file in directoryFiles)
{
    PdfDocument pdf = new PdfDocument();
    try
    {
        pdf.LoadFromFile(file.FullName);
    }
    catch (Exception exception)
    {
        builder.AppendLine("The error of loading " + file.FullName + " is: " + exception.Message);
        //Skip the current loop and force to next loop
        continue;
    }

    bool isPortfolio = pdf.IsPortfolio;
    if (isPortfolio)
    {
        builder.AppendLine(file.FullName + " is a Portfolio!");
    }
}
File.WriteAllText(@"c:\data.txt", builder.ToString());
