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;

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 }

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 }

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 }

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 }
