我正在编写一个应用程序来删除超过 6 个月的测试文件夹上的文件,该应用程序工作正常,因为我已经对其进行了测试,我想创建一个日志文件来跟踪已删除文件的名称以用于审计目的。
但是下面的脚本确实记录了所有文件(已删除和未删除),我只需要记录日期和时间以及已删除文件的名称即可。
谢谢
下面的脚本:
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();
        }
    }
