C#监视文件夹,显示文件夹操作到listView上
代码实现,以前在学校生活写的,就几句代码

}
private FileSystemWatcher watcher = new FileSystemWatcher();
private delegate void mydel(String str);//声明一个委托
private mydel MyDel;//声明一个全局的委托实例

{

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

FileSystemWatch(txbFolder.Text);
MyDel = new mydel(AddTolist);
}
}
///

private void AddTolist(string str)
{
lstbResult.Items.Add(str);
}

lstbResult.Invoke(MyDel, str);
}
#region 文件监视操作
private void FileSystemWatch(string path)
{
watcher.Path = path;
watcher.Created += new FileSystemEventHandler(OnCreate);

watcher.Renamed += new RenamedEventHandler(OnRenamed);
watcher.IncludeSubdirectories = true;
watcher.EnableRaisingEvents = true;
}
private void OnChanged(object source, FileSystemEventArgs e)

#endregion
}
}
java回调
public interface CallBack{
public void callBack();
}
