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.
