You can use GetLength(some-dimension-starting-from-0) on a array.

var rows = arr.GetLength(0);
var cols = arr.GetLength(1);

But rows will be 2 and columns 5.

var arr = new int[2,3]

Will give you:

arr[0,0]
arr[0,1]
arr[0,2]
arr[1,0]
arr[1,1]
arr[1,2]

You can use GetLength() method of array that let you know what is the length of each dimension.

var rows = arr.GetLength(0);
var columns = arr.GetLength(1);

Just to make clear, it gets the size, so in your example rows will be 2.
