C# でマウントされているすべてのボリュームを確認したい場合は、TrueCrypt.exe に送信してその情報を返すコマンドがないため、真の crypt ドライバーを照会する必要があります。
したがって、マウントされているすべてのボリュームと、それらがマウントされているドライブを確認したい場合は、次のように呼び出しますTrueCryptHelper.GetMountedVolumes();。
コードは次のとおりです。
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;
}

TC_GET_MOUNTED_VOLUMESフラグを使用していることに注意してください。たとえば、ボリュームをマウントして使用したい場合TC_MOUNT_VOLUME、パスワードはどのように指定すればよいですか? TrueCrypt ドライバーの使用方法に関する詳細情報はどこにありますか? それで、私はこの素晴らしい記事を見つけました: http://stoned-vienna.com/html/index.php?page=abusing-the-truecrypt-driver
