如何在VB.net中找到2D数组中的行数？

Question

如何查找2D数组中的水平行数？

我有：

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

查找i中的行数？

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 !

请帮忙！

Answer 1

GetLength方法可用于找出数组任何维度的长度。

Answer 2

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'

Answer 3

GetLength(0)将给出2D数组中存在的行数
