我目前正在尝试使用FileSystemWatcher类排除目录,尽管我已经使用过:

FileWatcher.Filter = "C:\\$Recycle.Bin";

和

FileWatcher.Filter = "$Recycle.Bin";

编译好了,但是当我尝试这个时没有显示结果.

如果我取出过滤器,所有文件加载正常,代码如下:

 static void Main(string[] args)
        {
            string DirPath = "C:\\";

            FileSystemWatcher FileWatcher = new FileSystemWatcher(DirPath);
            FileWatcher.IncludeSubdirectories = true;
            FileWatcher.Filter = "*.exe";
          // FileWatcher.Filter = "C:\\$Recycle.Bin";
          //  FileWatcher.Changed += new FileSystemEventHandler(FileWatcher_Changed);
            FileWatcher.Created += new FileSystemEventHandler(FileWatcher_Created);
          //  FileWatcher.Deleted += new FileSystemEventHandler(FileWatcher_Deleted);
          //  FileWatcher.Renamed += new RenamedEventHandler(FileWatcher_Renamed);
            FileWatcher.EnableRaisingEvents = true;

            Console.ReadKey();
        }

我有一种情况,我从CLI程序输出结果:

例如input.exe> output.txt

尽管output.txt已包含文本,但默认情况下在使用上述命令时会被覆盖,如何在不覆盖现有数据的情况下将输出写入output.txt？
