String to byte[] reloaded

Hi
I need an efficient method to convert a string object to it's byte[]
equivalent.
I know there are LOTS of methods, but they lack in efficiency. All
methods allocate new memory to create the byte[] array. Of course,
when memory allocation occurs, then naturally extra processing power
is needed.
To more explicit, MFC introduced a super-efficient method of dealing
with this situation. As far as I remember (I switched from MFC
to .NET
few years ago), MFC's CString class has a method with the following
signature:

byte[] GetBuffer()


This method "blocks" the CString instance until ReleaseBuffer()
method
is called. Again, maybe the method names are not quite as I remember,
but the important thing is the principle.
The marvelous result is that you may freely iterate through the
byte[]
array returned by GetBuffer() method and even modify it (with respect
to some limits, of course), and all this, without allocating new
memory.
My question is: using MemoryStream class will do the job for me? I
mean, there is a method called GetBuffer(), but will it allocate new
memory or not, as it is not stated in MS documentation.


Thanks

Sorry about that and thanks for your responses.
Anyway, is there a way to put the same question in 2 or more groups?

Thanks.
