对于VB中的循环

Question

我有一个5乘5的矩阵我想填充，我想简化成for循环。

据我所知，我需要2个循环来完成这项任务？

我仍然很新的VB希望你能理解

Dim x(4, 4) As Char 

    x(0, 0) = Mid(key, 1, 1) 
    x(0, 1) = Mid(key, 2, 1) 
    x(0, 2) = Mid(key, 3, 1) 
    x(0, 3) = Mid(key, 4, 1) 
    x(0, 4) = Mid(key, 5, 1) 
    x(1, 0) = Mid(key, 6, 1) 
    x(1, 1) = Mid(key, 7, 1) 
    .... 
    x(4, 4) = Mid(key, 25, 1) 

Answer 1

尝试是这样的：

Dim x As Integer 
Dim y As Integer 
Dim myMatrix(4, 4) As Char 

For x = 0 To 4 
    For y = 0 To 4 
     myMatrix(x, y) = Mid(key, (x * 5) + y + 1, 1) 
    Next
