How to dynamically expand a Memory Mapped File

Question

I\'ve used C# to solve the following requirement.. - create an app the can receive a lot of data fast - you must be able to analyse the received data while more are incoming

Answer 1

I found that closing and recreating the mmf with the same name but new size works to all intents and purposes

                using (var mmf = MemoryMappedFile.CreateOrOpen(SenderMapName, 1))
                {
                    mmf.SafeMemoryMappedFileHandle.Close();
                }
                using (var sender = MemoryMappedFile.CreateNew(SenderMapName, bytes.Length))

and it's really fast.
