How to add values ​​to a 2D array?

Question

Arrays

Good evening! Can you please tell me how to add values ​​to a two-dimensional array?
There is an array: int[,] array = { {1, 2, 3}, {4, 5, 6} };
You need to do something like this: array += {7, 8, 9}; To become array = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
How can you do that?
PS Thank you!

Arrays, they are arrays because you can't add values ​​to them.
Use an array list: List and add arrays via Add.
