dotnet interop:

In managed c++, what is the most efficient way to copy the contents of a
native buffer (BYTE*) to a managed stream?

thanks

Thanks, it appears that the UnmanagedMemoryStream can't be chained to
another stream. Would be nice if you could write a block of native memory
to the UnmanagedStream and have it write to the chained / underlying stream.

As of .NET 2.0 you can use the System.IO.UnmanagedMemoryStream. It
wraps the native buffer directly so it doesn't require any copying.
