Hi Raymond, You are right. True multidimensional arrays are not supported now in binary serialized (C#). Jugged arrays work fine. So, you can use them or just one-dimensional array with 2D-index calculation.
Anyway, I opened a ticket: https://issues.apache.org/jira/browse/IGNITE-6896 You can track a progress on this issue. Thank you, Alexey -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
