C#監視文件夾,顯示文件夾操作到listView上

代碼實現,以前在學校生活寫的,就幾句代碼

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;

using System.Threading;

namespace FileWatch

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private FileSystemWatcher watcher = new FileSystemWatcher();

private delegate void mydel(String str);//聲明一個委托

private mydel MyDel;//聲明一個全局的委托實例

///

/// 選擇文件夾并開始監視

///

///

///

private void btnChooseFolder_Click(object sender, EventArgs e)

{

FolderBrowserDialog fd = new FolderBrowserDialog();

if (fd.ShowDialog() == DialogResult.OK)

{

txbFolder.Text = fd.SelectedPath;

FileSystemWatch(txbFolder.Text);

MyDel = new mydel(AddTolist);

}

}

///

/// 增加到列表

///

///

private void AddTolist(string str)

{

lstbResult.Items.Add(str);

}

///

/// 獲取對文件夾操作的信息

///

/// 信息字符串

private void GetInfo(string str)

{

lstbResult.Invoke(MyDel, str);

}

#region 文件監視操作

private void FileSystemWatch(string path)

{

watcher.Path = path;

watcher.Created += new FileSystemEventHandler(OnCreate);

watcher.Deleted += new FileSystemEventHandler(OnDelete);

watcher.Renamed += new RenamedEventHandler(OnRenamed);

watcher.IncludeSubdirectories = true;

watcher.EnableRaisingEvents = true;

}

private void OnChanged(object source, FileSystemEventArgs e)

{

GetInfo(e.Name + " 被 修改. " + DateTime.Now.ToShortTimeString());

}

private void OnCreate(object source, FileSystemEventArgs e)

{

GetInfo(e.Name + " 被 創建." + DateTime.Now.ToShortTimeString());

}

private void OnDelete(object source, FileSystemEventArgs e)

{

GetInfo(e.Name + " 被 刪除." + DateTime.Now.ToShortTimeString());

}

private void OnRenamed(object source, FileSystemEventArgs e)

{

GetInfo(e.Name + " 被 重命名" + DateTime.Now.ToShortTimeString());

}

#endregion

}

}

java回調

public interface CallBack{

public void callBack();

}

總結
