Best way to use unmanaged buffer as a Byte []? preferably w/o copying from native to managed memory

[lallous]

Hello

I am writing managed c++/c++ native code.

We have soem buffer passed as char* from native, and we want to pass to a
managed MemoryStream object.

Is it possible to have a Byte [] reference that char* and then we set the
Byte[] size?

Or this:

Is the only suggest way?

The reason I look for an alternative is that because I come fron a native
background and copying memory over and over is a concern.

Use System::IO::UnmanagedMemoryStream.

You shouldn't, as long as a profiler hasn't proved that there is
indeed a performance bottleneck (this is true, as well for native as
for managed code).
