对于VB中的循环

Question

我有一个5×5矩阵我想填充,我想简化为for循环.

据我所知,我需要2个for循环才能完成这项任务？

我对VB仍然很陌生,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

尝试这样的事情:

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
