I need to get every possible combination of characters that follows a rule.
我需要获得遵循规则的每个可能的字符组合。
Say:
说：
Length: 5-6
Characters: ABCabc123
长度：5-6个字符：ABCabc123
I should get stuff back like this:
我应该这样回来：
AAAAA
AAAAB
AAABA
AAABB
..
..
AcbC13
Is there any way to do this quick an efficiently?
有没有办法快速有效地做到这一点？
Please keep in mind I am using VB.net but I do understand concepts related to just general speaking.
请记住我使用的是VB.net，但我确实理解与一般说法相关的概念。
