推荐答案

看看

Take a look at File.SetAttributes(). There are lots of examples online about how to use it.

来自该MSDN页面:

FileAttributes attributes = File.GetAttributes(path);

        if ((attributes & FileAttributes.Hidden) == FileAttributes.Hidden)
        {
            // Show the file.
            attributes = RemoveAttribute(attributes, FileAttributes.Hidden);
            File.SetAttributes(path, attributes);
            Console.WriteLine("The {0} file is no longer hidden.", path);
        } 
        else 
        {
            // Hide the file.
            File.SetAttributes(path, File.GetAttributes(path) | FileAttributes.Hidden);
            Console.WriteLine("The {0} file is now hidden.", path);
        }
