Если я хочу увидеть все тома, смонтированные с помощью С#, мне придется запросить настоящий драйвер шифрования, потому что нет команды, которую я могу отправить в TrueCrypt.exe, которая вернет мне эту информацию.
Поэтому, если я хочу увидеть все смонтированные тома и на какой диск они смонтированы, я вызову TrueCryptHelper.GetMountedVolumes();:
вот код:
public static class TrueCryptHelper
{
public static Dictionary<char, string> GetMountedVolumes()
{
uint size = (uint)Marshal.SizeOf(typeof(MOUNT_LIST_STRUCT));
IntPtr buffer = Marshal.AllocHGlobal((int)size);
uint bytesReturned;
IntPtr _hdev = CreateFile("\\\\.\\TrueCrypt", FileAccess.ReadWrite, FileShare.ReadWrite, IntPtr.Zero, FileMode.Open, 0, IntPtr.Zero);
bool bResult = DeviceIoControl(_hdev, TC_GET_MOUNTED_VOLUMES, buffer, size, buffer, size, out bytesReturned, IntPtr.Zero);
MOUNT_LIST_STRUCT mount = new MOUNT_LIST_STRUCT();
Marshal.PtrToStructure(buffer, mount);
Marshal.FreeHGlobal(buffer);
Dictionary<char, string> items = new Dictionary<char, string>();
for (int i = 0; i < 26; i++)
{
string filePath = mount.wszVolume[i].ToString().Replace(@"\??\", "");
if (filePath.Length > 2)
{
items[(char)('A' + i)] = filePath;
}
//Console.WriteLine("{0}: => {1}", (char)('A' + i), mount.wszVolume[i]);
}
return items;
}

Обратите внимание, что я использую флаг TC_GET_MOUNTED_VOLUMES. Например, если я хочу смонтировать том и использовать TC_MOUNT_VOLUME, как мне указать пароль? Где я могу найти дополнительную информацию об использовании драйвера TrueCrypt? Итак, я нашел эту замечательную статью: http://stoned-vienna.com/html/index.php?page=abusing-the-truecrypt-driver
