问题描述
我有一个ArrayList [] myList中，我试图创建数组中的值的所有排列的列表。
I have an ArrayList[] myList and I am trying to create a list of all the permutations of the values in the arrays.
如：（所有值都是字符串）
EXAMPLE: (all values are strings)
myList[0] = { "1", "5", "3", "9" };
myList[1] = { "2", "3" };
myList[2] = { "93" };
myList中的计数可以变化，以便其长度事先不知道。
The count of myList can be varied so its length is not known beforehand.
我希望能够生成所有排列的列表类似于以下（但有一些额外的格式）。
I would like to be able to generate a list of all the permutations similar to the following (but with some additional formatting).
1 2 93
1 3 93
5 2 93
5 3 93
3 2 93
3 3 93
9 2 93
9 3 93
请问一下，我试图完成这个有意义吗？我似乎无法拿出这样做的一个好方法，（如果有的话）。
Does this make sense of what I am trying to accomplish? I can't seem to come up with a good method for doing this, (if any).
编辑：
我不知道，如果递归将与我的愿望，格式化输出在我自己的方式干涉。对不起，我没有什么之前，我是格式化提。
I am not sure if recursion would interfere with my desire to format the output in my own manner. Sorry I did not mention before what my formatting was.
我要结束了建筑上的所有组合的String []数组下面的格式如下图所示：
I want to end up building a string[] array of all the combinations that follows the format like below:
为1 2 93置换
我想输出是val0 = 1; VAL1 = 2;将val2 = 93;
I want the output to be "val0=1;val1=2;val2=93;"
我将与递归实验了。谢谢DrJokepu
I will experiment with recursion for now. Thank you DrJokepu
推荐答案
我很惊讶没有人张贴的LINQ的解决方案。
I'm surprised nobody posted the LINQ solution.
from val0 in new []{ "1", "5", "3", "9" }
from val1 in new []{ "2", "3" }
from val2 in new []{ "93" }
select String.Format("val0={0};val1={1};val2={2}", val0, val1, val2)
