How to best send a 2D integer array to clients?

I need to send an integer array to my clients on the network. This would be a very irregular thing (maybe as little as once per session), so bandwidth isn’t really a concern. This is how I've attempted it:

int[,] myArray = new int[100,100];
//...Fill Array ...
RpcSendArray(myArray);

This gives me the following error message:
"UnityException: NetworkWriter used buffer is too big!"
What would be the easiest method of sending this sort of data?

 

Split it into smaller messages or use another netlib.
