C#: help with coding

[Shani Aulakh]

Hi All,
I have the following class which deletes files older than X number of days and with specific extension. I dont see any error in the code from my point of you. Please, can anyone double check for me because when i m debuging it, files are not getting deleted. Thanks:)

using System;
using System.IO;
using System.Collections;
 
namespace Files_ExtLib1
{
    public class FolderWatcher
    {
        string m_FolderPath;
 
        public FolderWatcher()
        {
            //
            // TODO: Add constructor logic here
            //
        }
 
        #region Property
        public string FolderPath
        {
            get
            {
                return m_FolderPath;
            }
            set
            {
                m_FolderPath = value;
            }
        }
        #endregion
 
        public int DeleteFilesOlderThan(int Days, int Hrs, int Mins, string filter)
        {
            DateTime dt = GetRelativeDateTime(Days, Hrs, Mins);
            ArrayList oldFilePaths = FilesOlderThan(dt, filter);
            int count = 0;
            foreach (string filePath in oldFilePaths)
            {
                try
                {
                    File.Delete(filePath);
                    count++;
                }
                catch (Exception e)
                {
                    Console.WriteLine("Unable to delete " + filePath);
                    Console.WriteLine("Reason: {0} ", e);
                }
                Console.WriteLine("Files successfully deleted");
            }
            return count;
        }
 
        // Using GetRelativeDateTime as a private method instead of public however as it is only to be used internally
        private static DateTime GetRelativeDateTime(int days, int hours, int minutes)
        {
            return DateTime.Now.AddDays(-days).AddHours(-hours).AddMinutes(-minutes);
        }
 
        public ArrayList FilesOlderThan(DateTime dt, string filter)
        {
            // Using the supplied path 
            DirectoryInfo directory = new DirectoryInfo(m_FolderPath);
            // Filter is applied to the directory.GetFiles method to get files of given extension
            // get FileInfos for the files in the current directory matching the filter expression
            FileInfo[] files = directory.GetFiles(filter);
            //list to hold the result
            ArrayList older = new ArrayList();  
            foreach (FileInfo file in files)
            {
                //if smaller (older) than the relative time 
                if (file.CreationTime < dt) 
                    older.Add(file.Name); //add it to the list 
            }
            return older;
        }
    }
}
 

Entry point

        private void DeleteFiles_Click(object sender, EventArgs e)
        {
            FolderWatcher fw = new FolderWatcher();
            fw.FolderPath = @"c:\csharp"; // FolderName
            //OpenFileDialog OpenFileDialog1 = new OpenFileDialog();
            fw.DeleteFilesOlderThan(int.Parse(Textbox1.Text), int.Parse(Textbox2.Text), int.Parse(Textbox3.Text), "*" + filetype.SelectedItem.ToString()); // deletes everything older than specified days,hrs, and mins respectively
