如何使用文件系统驱动程序隐藏C#中的目录？

要在C#中使用文件系统驱动程序隐藏目录，请遵循以下步骤：

首先，确保已安装.NET Framework 4.0或更高版本。
在Visual Studio中创建一个新的C#控制台应用程序项目。
添加以下代码：

using System;
using System.IO;
using System.Runtime.InteropServices;
using System.Security.AccessControl;
using System.Security.Principal;

namespace HideDirectory
{
    class Program
    {
        [DllImport("kernel32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
        static extern IntPtr CreateFile(
            string lpFileName,
            uint dwDesiredAccess,
            uint dwShareMode,
            IntPtr lpSecurityAttributes,
            uint dwCreationDisposition,
            uint dwFlagsAndAttributes,
            IntPtr hTemplateFile);

        static void Main(string[] args)
        {
            string folderPath = @"C:\MyHiddenFolder";
            try
            {
                if (!Directory.Exists(folderPath))
                {
                    Directory.CreateDirectory(folderPath);
                }

                HideFolder(folderPath);
                Console.WriteLine($"Folder {folderPath} has been hidden.");
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Error: {ex.Message}");
            }
        }

        static void HideFolder(string folderPath)
        {
            var folderInfo = new DirectoryInfo(folderPath);
            var hFile = CreateFile(
                folderInfo.FullName,
                GENERIC_READ | GENERIC_WRITE,
                FILE_SHARE_READ | FILE_SHARE_WRITE,
                IntPtr.Zero,
                OPEN_EXISTING,
                FILE_FLAG_BACKUP_SEMANTICS,
                IntPtr.Zero);

            if (hFile.ToInt32() != -1)
            {
                try
                {
                    uint fileAttributes = GetFileAttributes(hFile);
                    fileAttributes |= FILE_ATTRIBUTE_HIDDEN;
                    SetFileAttributes(hFile, fileAttributes);
                }
                finally
                {
                    CloseHandle(hFile);
                }
            }
        }

        const uint GENERIC_READ = 0x80000000;
        const uint GENERIC_WRITE = 0x40000000;
        const uint FILE_SHARE_READ = 0x00000001;
        const uint FILE_SHARE_WRITE = 0x00000002;
        const uint OPEN_EXISTING = 0x00000003;
        const uint FILE_FLAG_BACKUP_SEMANTICS = 0x02000000;
        const uint FILE_ATTRIBUTE_HIDDEN = 0x00000002;

        [DllImport("kernel32.dll", SetLastError = true)]
        static extern uint GetFileAttributes(IntPtr hFile);

        [DllImport("kernel32.dll", SetLastError = true)]
        static extern bool SetFileAttributes(IntPtr hFile, uint fileAttributes);

        [DllImport("kernel32.dll", SetLastError = true)]
        static extern bool CloseHandle(IntPtr hObject);
    }
}
