c#文件夹加密隐藏

如果你想在C#中加密和隐藏文件夹，可以使用以下步骤：

1. 选择要加密和隐藏的文件夹。
2. 使用C#中的AES加密算法对文件夹进行加密。
3. 将加密后的文件夹移动到一个隐藏文件夹中。
4. 使用C#中的文件系统对象隐藏该文件夹，使其在操作系统中不可见。

以下是一些示例代码，可以帮助你实现这些步骤：

使用AES加密算法加密文件夹：

string password = "myPassword";
string folderPath = @"C:\MyFolder";

// Create a new AES object
Aes aes = Aes.Create();

// Generate a random initialization vector
byte[] iv = aes.IV;

// Create a new encryption key using the password and IV
Rfc2898DeriveBytes keyDerivation = new Rfc2898DeriveBytes(password, iv);
byte[] key = keyDerivation.GetBytes(32);

// Create a new encryption stream
using (FileStream inputFileStream = new FileStream(folderPath, FileMode.Open))
using (FileStream outputFileStream = new FileStream(folderPath + ".encrypted", FileMode.Create))
using (ICryptoTransform encryptor = aes.CreateEncryptor(key, iv))
using (CryptoStream cryptoStream = new CryptoStream(outputFileStream, encryptor, CryptoStreamMode.Write))
{
    // Encrypt the input file stream and write it to the output file stream
    inputFileStream.CopyTo(cryptoStream);
}

// Delete the original folder
Directory.Delete(folderPath, true);

将加密后的文件夹移动到一个隐藏文件夹中：

string hiddenFolderPath = @"C:\MyHiddenFolder";

// Create the hidden folder if it doesn't exist
if (!Directory.Exists(hiddenFolderPath))
{
    Directory.CreateDirectory(hiddenFolderPath);
}

// Move the encrypted folder to the hidden folder
string encryptedFolderPath = folderPath + ".encrypted";
File.Move(encryptedFolderPath, hiddenFolderPath + "\\" + Path.GetFileName(encryptedFolderPath));

使用文件系统对象隐藏该文件夹：

string folderName = Path.GetFileName(folderPath);
string hiddenFolderPath = @"C:\MyHiddenFolder";

// Hide the folder by setting its attributes to hidden
File.SetAttributes(hiddenFolderPath + "\\" + folderName, FileAttributes.Hidden);
