The output of the cipher not embedded into any protocol (like
Such a protocol needs to specify for example where to put the IV,
what key size is used etc. I don't know the CryptStream stuff from
C#; it might have some defaults to create a stream in some protocol.
To write a compatible implementaion, one needs to know at least the
key size, the mode of operation (e.g. CBC or CFB) and the way padding

You also need how to transform a key from whatever ASCII format to the
format actually used. In general keys are not used directly but
preprocessed to match the required key length of the algorithm.
