如何找到2D數組中的水平行數？

我有 ：

   Dim i(,) As Integer = {{2, 5, 6, 7}, {32, 5, 4, 2}}

找到i中的行數？

例如 ：

 // Here, array i has 2 sets of data i.e. 2 rows
 // set1 = {2,5,6,7} and set2 = {32,5,4,2}
 // So, I want the number of sets i.e 2 in this case !

請幫忙 ！

Answer 1

GetLength方法可用於查找數組的任何維度的長度。

Answer 2

我相信這段代碼應該適合你：

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'

Answer 3

GetLength(0)將給出2D數組中存在的行數
