关于c#：使用FileWatcher检测文件夹中是否有新文件创建

Detect if there are new files created in a folder using FileWatcher

我想知道在给定目录中是否创建了新文件。我有下一个代码：

private static void CreateWatcher()
{
//Create a new FileSystemWatcher.
FileSystemWatcher watcher = new FileSystemWatcher();

//Set the filter to all files.
watcher.Filter ="*.*";

//Subscribe to the Created event.
watcher.Created += new FileSystemEventHandler(watcher_FileCreated);

//Set the path
watcher.Path = path;

//Enable the FileSystemWatcher events.
watcher.EnableRaisingEvents = true;
}

private static void watcher_FileCreated(object sender, FileSystemEventArgs e)
{
Console.WriteLine("Nuevo archivo creado ->" + e.Name);
}

public static void Main(string[] args)
{
CreateWatcher();
CreateFiles();
Console.Read();
}

在 CreatedFiles() 函数中，我在路径上创建了三个新文件(一个 zip 和两个 txt)。它检测到两个 txt 文件，但与 zip 文件不同。我该如何解决？
