I am writing an application to delete file on a test folder that are over 6 months, the application works fine as I have tested it, I wanted to create a log file to keep track of the name of the deleted files for audit purpose.
but with the scirpt below it does record all the files (deleted and undeleted), all I need is just record the date and time and the name of the deleted files.
Thank you
Script Below:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO;
namespace Delete_PDF_Files
{
public partial class Form1 : Form
{
private string strLogText;
public Form1()
{
InitializeComponent();
}
private void btnCheck_Click(object sender, EventArgs e)
{
// check the number of file in the CPS directory on S drive
listBox1.Items.Clear();
string[] files = System.IO.Directory.GetFiles(@"C:\test\"); // @"S:\CPS Papers\"
this.listBox1.Items.AddRange(files);
textBox1.Text = listBox1.Items.Count.ToString();
}
// delete button to delete files over 6 months from CPS folder
private void btnDelete_Click(object sender, EventArgs e)
{
string[] files = System.IO.Directory.GetFiles(@"C:\test\"); //S:\CPS Papers test C:\test\
foreach (string file in files)
{
System.IO.FileInfo fi = new System.IO.FileInfo(file);
if (fi.LastWriteTime < DateTime.Now.AddMonths(-6))
fi.Delete();
// Create a writer and open the file: //C:\test\log
System.IO.StreamWriter log;
if (!System.IO.File.Exists("C:\\test\\log\\logfile.txt"))
{
log = new System.IO.StreamWriter("C:\\test\\log\\logfile.txt");
}
else
{
log = File.AppendText("C:\\test\\log\\logfile.txt");
}
// Write to the file:
log.WriteLine(DateTime.Now);
log.WriteLine(strLogText);
log.WriteLine();
log.WriteLine();
// Close the stream:
log.Close();
}
}
// Exit button
private void btnExit_Click(object sender, EventArgs e)
{
Application.Exit();
}
}
}
Replace you delete code with this one:
private void btnDelete_Click(object sender, EventArgs e)
{
string[] files = System.IO.Directory.GetFiles(@"C:\test\"); //S:\CPS Papers test C:\test\
foreach (string file in files)
{
System.IO.FileInfo fi = new System.IO.FileInfo(file);
//if (fi.LastAccessTime < DateTime.Now.AddMonths(-3))
if (fi.LastWriteTime < DateTime.Now.AddMonths(-6))
{
fi.Delete();
using (StreamWriter writer = File.AppendText("C:\\test\\log\\logfile.txt"))
{
writer.Write("File: " + file + " deleted at : "+DateTime.Now);
writer.WriteLine("----------------------------------------------------");
writer.Flush();
writer.Close();
}
}
}
}
Instead of using custom logging as you are doing I would recommend that you use a good library like Log4Net . Why reinvent the wheel? I know that it has a small learning curve time but once you get to know you you can easily integrate it in any new projects.
By just adding a config section to your app.config as given here and a few lines of code you should be ready to go.
A good tutorial on Log4Net can be found here
