[C#] FileSystemWatcher

這是一個讓我覺得有趣的元件…
他是用來監控檔案是否有新增刪除修改…
詳細的介紹還是看msdn吧…
來點小範例…

void Main()
{
    FileSystemWatcher fsw = new FileSystemWatcher();
    fsw.Path = @"D:\";
    fsw.Filter = "*.txt";
    fsw.Created += new FileSystemEventHandler(fsw_Created);
    fsw.Changed += new FileSystemEventHandler(fsw_Changed);
    fsw.EnableRaisingEvents = true;
 }

void fsw_Changed(object sender, FileSystemEventArgs e)
{
    Console.WriteLine("File: " + e.FullPath + " " + e.ChangeType);
}

void fsw_Created(object sender, FileSystemEventArgs e)
{
    Console.WriteLine("File: " + e.FullPath + " " + e.ChangeType);
}
