optimising binary serialization multi-dimensional general arrays

i have category i need binary serialize. category contains domain below:

private t[,] m_data;

these multi-dimensional arrays sincerely infinite (hundreds thousands elements) any obsolete type. i attempted customary .net serialization an vigilant record combined hoop infinite i cruise .net storing lot steady information component forms presumably good done.

i have looked around tradition serializers nonetheless have seen any understanding multi-dimensional general arrays. i have also experimented built-in .net concentration byte array memory tide following serializing success, nonetheless discerning / dense i hoped.

my doubt is, should i try tradition serializer optimally serialize array suitable form (this seems small daunting), should i customary .net serialization supplement compression?

any recommendation best proceed many appreciated, links resources arrangement tackle serialization multi-dimensional general array - mentioned i have found support such structures.
