pdf reader class.i think may be foreach loop is very usefull in collection code

my code like as:

C#

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.IO;
using System.Collections;
using System.Windows.Forms;
using iTextSharp.text.pdf;
using iTextSharp.text.pdf.parser;

namespace test
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
   
        public static string ExtractTextFromPdf(string path)
        {
            using (PdfReader reader = new PdfReader(path))
            {
                StringBuilder text = new StringBuilder();

                for (int i = 1; i <= reader.NumberOfPages; i++)
                {
                    text.Append(PdfTextExtractor.GetTextFromPage(reader, i));
                    
                }

                return text.ToString();
            }

        } 
             private void button1_Click(object sender, EventArgs e)
            {
            Form1.ExtractTextFromPdf(@"D:\Data Sets\Enron\168.pdf");
            }
            
        }
        }

my requirement is how to read all pdf files(collection) like path will be as

"@"D:\Data Sets\Enron".Enron folder conatin set of pdf files then each time pick up

one pdf file and read the content. i think may be foreach is very usefull.

This snippet shows you how to get all PDF file names in your directory
and then how to iterate through this:

C#

string pathName = @"D:\Data Sets\Enron";

string[] pdfFileNames = Directory.GetFiles(pathName, "*.pdf");

foreach(string pdfFileName in pdfFileNames)
{
    ExtractTextFromPdf(pdfFileName);
}
