c# - Most efficient data type for UUID in database besides a native UUID -

-

what efficient data type store uuid/guid in databases not have native uuid/guid data type? 2 bigints?

and efficient code (c# preferred) convert , guid type?

thanks.

it's hard efficient without knowing database using.

my first inclination use binary(16) column.

as using value in c#, system.guid type has constructor accepts byte[] array, , method tobytearray() returns byte array.
