IStream to Stream -anybody know?(COM->C#)

[Asteroid]

Hello people! I have ATL COM Server, there are some important functions, which pass IStream* arguments. I have no problems with diffrent types, but one type, which i cannot convert to C# type. How can convert from IStream(COM) to Stream(C# client)
For me is not important type in C#, i need onli get data from IStream.
Thank you!
