来源： FileSystemWatch 对文件的监测 修改 创建 删除 并写入日志 – RunningMan1229 – 博客园
我做的这个主要是用来对文件的监测 修改 创建 删除 并写入日志
此外我做的WinForm程序
首先导入命名空间
1 using System.IO;
申明全局变量
1 private FileSystemWatcher watch = new FileSystemWatcher();
2 private FileStream fs = null;
2 private FileStream fs = null;
先写一个写日志的方法，我这里写的路径都是固定的，你们可以给这个路径配置在App.config中，用户可以选择路径，选择完以后
修改config文件，下次用的时候可以默认选择上次的路径，这里我就不做了
1 public void write(string message)
2 {
3 string path = “C:\\Log\\”;
4 if (!Directory.Exists(path))
5 {
6 Directory.CreateDirectory(path);
7 }
8 string fileName = path + “Log.txt”;
9
10 if (!File.Exists(fileName))
11 {
12 FileStream file = new FileStream(fileName, FileMode.Create);
13 file.Dispose();
14 }
15 fs = new FileStream(fileName, FileMode.Append, FileAccess.Write);
16 StreamWriter sw = new StreamWriter(fs, Encoding.UTF8);
17 sw.WriteLine(message);
18 sw.WriteLine(“———————–“);
19 sw.Dispose();
20 fs.Dispose();
21 }
2 {
3 string path = “C:\\Log\\”;
4 if (!Directory.Exists(path))
5 {
6 Directory.CreateDirectory(path);
7 }
8 string fileName = path + “Log.txt”;
9
10 if (!File.Exists(fileName))
11 {
12 FileStream file = new FileStream(fileName, FileMode.Create);
13 file.Dispose();
14 }
15 fs = new FileStream(fileName, FileMode.Append, FileAccess.Write);
16 StreamWriter sw = new StreamWriter(fs, Encoding.UTF8);
17 sw.WriteLine(message);
18 sw.WriteLine(“———————–“);
19 sw.Dispose();
20 fs.Dispose();
21 }
写监测的方法，我这里只是记录了一部分信息
1 public void ReNameWatch(object sender, FileSystemEventArgs e)
2 {
3 write(DateTime.Now.ToString(“yyyy-MM-dd hh:mm:ss”) + ” ReName File : ” + e.Name.ToString());
4 }
5
6 public void DeleteWatch(object sender, FileSystemEventArgs e)
7 {
8 write(DateTime.Now.ToString(“yyyy-MM-dd hh:mm:ss”) + ” Delete File : ” + e.Name.ToString());
9 }
10
11 public void CreateWatch(object sender, FileSystemEventArgs e)
12 {
13 write(DateTime.Now.ToString(“yyyy-MM-dd hh:mm:ss”) + ” Create File : ” + e.Name.ToString());
14 }
15
16 public void ChangeWatch(object sender, FileSystemEventArgs e)
17 {
18 write(DateTime.Now.ToString(“yyyy-MM-dd hh:mm:ss”) + ” Change File : ” + e.Name.ToString());
19 }
2 {
3 write(DateTime.Now.ToString(“yyyy-MM-dd hh:mm:ss”) + ” ReName File : ” + e.Name.ToString());
4 }
5
6 public void DeleteWatch(object sender, FileSystemEventArgs e)
7 {
8 write(DateTime.Now.ToString(“yyyy-MM-dd hh:mm:ss”) + ” Delete File : ” + e.Name.ToString());
9 }
10
11 public void CreateWatch(object sender, FileSystemEventArgs e)
12 {
13 write(DateTime.Now.ToString(“yyyy-MM-dd hh:mm:ss”) + ” Create File : ” + e.Name.ToString());
14 }
15
16 public void ChangeWatch(object sender, FileSystemEventArgs e)
17 {
18 write(DateTime.Now.ToString(“yyyy-MM-dd hh:mm:ss”) + ” Change File : ” + e.Name.ToString());
19 }
写按钮点击事件
1 public void Watch(object sender, EventArgs e)
2 {
3 if (this.button1.Text == “Start”)
4 {
5 string path = “C:\\”;
6 watch.Path = path;
7 watch.Filter = “*.txt”;
8 watch.NotifyFilter = NotifyFilters.FileName | NotifyFilters.Size | NotifyFilters.LastWrite | NotifyFilters.Attributes | NotifyFilters.CreationTime | NotifyFilters.DirectoryName | NotifyFilters.LastAccess | NotifyFilters.Security;
9
10 watch.Renamed += new RenamedEventHandler(ReNameWatch);
11 watch.Deleted += new FileSystemEventHandler(DeleteWatch);
12 watch.Created += new FileSystemEventHandler(CreateWatch);
13 watch.Changed += new FileSystemEventHandler(ChangeWatch);
14
15 watch.EnableRaisingEvents = true;
16 this.button1.Text = “Stop”;
17 }
18 else if (this.button1.Text == “Stop”)
19 {
20 watch.EnableRaisingEvents = false;
21 this.button1.Text = “Start”;
22 }
23 }
2 {
3 if (this.button1.Text == “Start”)
4 {
5 string path = “C:\\”;
6 watch.Path = path;
7 watch.Filter = “*.txt”;
8 watch.NotifyFilter = NotifyFilters.FileName | NotifyFilters.Size | NotifyFilters.LastWrite | NotifyFilters.Attributes | NotifyFilters.CreationTime | NotifyFilters.DirectoryName | NotifyFilters.LastAccess | NotifyFilters.Security;
9
10 watch.Renamed += new RenamedEventHandler(ReNameWatch);
11 watch.Deleted += new FileSystemEventHandler(DeleteWatch);
12 watch.Created += new FileSystemEventHandler(CreateWatch);
13 watch.Changed += new FileSystemEventHandler(ChangeWatch);
14
15 watch.EnableRaisingEvents = true;
16 this.button1.Text = “Stop”;
17 }
18 else if (this.button1.Text == “Stop”)
19 {
20 watch.EnableRaisingEvents = false;
21 this.button1.Text = “Start”;
22 }
23 }
写加载事件
1 public Two()
2 {
3 InitializeComponent();
4 this.KeyDown += new KeyEventHandler(Two_KeyDown);
5 this.button1.Click += new EventHandler(Watch);
6 }
2 {
3 InitializeComponent();
4 this.KeyDown += new KeyEventHandler(Two_KeyDown);
5 this.button1.Click += new EventHandler(Watch);
6 }
