主题：[求助]如何字符串随机组合

假设有字符：“一、二、三、中、上、下、左、右“字符；需要随机组合出多个字符串：一二三中上下左右、上二三中一下左右...；请问代码如何做到？

直接打乱

 

Dim str() As String = {"1", "2", "3", "4", "5", "6", "7", "8", "9", "0", "+", "-", "*", "/", ">"}
For i As Integer = 1 To str.Length '洗牌测次数
    Dim rnum1 As Integer = Rand.Next(str.Length)
    Dim rnum2 As Integer = Rand.Next(str.Length)
    Dim temp As String = str(rnum1)
    str(rnum1) = str(rnum2)
    str(rnum2) = temp   
Next
Dim data As String = String.Join("", str)
msgbox(data)

我找到这个代码是这样的：

Dim a() As String = {"135","138","139"}
Dim b() As String = {"0741","5987","3656","2135"}
Dim c() As String = {"5555","4444","6666","9999","8888"}
For Index As Integer = 0 To 90
    Dim nr As DataRow = DataTables("表A").addnew
    nr("第一列") = a(rand.Next(0,3)) & b(rand.Next(0,4)) & c(rand.Next(0,5))
Next

非常感谢您的解答。

Dim str As String = "135,138,139"

Dim a() As String = str.Split(",")
