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,应用程序运行正常,因为我测试过它,我想创建一个日志文件来跟踪已删除文件的名称以供审核目的
但是下面的scirpt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。
谢谢
以下脚本:
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();
}
}
}

将此删除代码替换为:
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();
}
}
}
}
