Hum... I think this is either simpler, or more complex than just that,
depending on how you look at it.
marat's asking about copying a char* to a character managed array. hence,
that likely means doing an encoding conversion, since that would imply
char* -> System::Char[]. In that case, I'd have to wonder if just creating a
temporary System::String object and then calling String::ToCharArray(),
wouldn't just be simpler.
If, on the oither hand, what he really wants is a char*->System::Byte[]
conversion, then the Copy() method of the Marshal class would probably be
faster than doing the loop yourself :)
