Decryption and encryption of Java RSA using C #

I encrypt the message and then decrypt it. Here is the gist: https://gist.github.com/2489899 . I have to store these keys in an xml scheme, because the message must also decrypt in C #. (This is just a "summary" of my program with a dam, etc.). But I always get an exception:

javax.crypto.BadPaddingException: Data must start with zero

Simple, your call to the RSAPrivateCrtKeySpec constructor uses the wrong order of parameters.
