I believe this code should work for you:
我相信这段代码应该适合你：
Dim array(56,67) As Integer 'Example array'
Dim x_axis As Integer = array.GetLength(0)-1 'To find out number of dimensions on the x'
Dim y_axis As Integer = array.GetLength(1)-1 'To find out number of dimensions on the y'

GetLength(0)will give the number of rows present in 2D array
GetLength(0)将给出二维数组中存在的行数
