How to get all possible combinations ?

Question

I have n numbers of  array contains n number of data.

I want to write out all the possible combinations.

For ex:-

var list1 = new List<string> { "A", "B", "C", "D" };

var list2 = new List<string> { "10", "20", "30", "40", "50" };

var list3 = new List<string> { "ABC", "DEF", "GHI", "JKL" };

Possible outputs :

A-10-ABC

A-10-DEF

A-10-GHI

A-10-JKL

A-20-ABC

A-20-DEF

A-20-GHI

A-20-JKL

A-30-ABC

A-30-DEF

A-30-GHI

A-30-JKL

........ and so on

The actual problem is the number of list variable is not constant, therefore I can't just write a fixed amount of nested loop.

Hope someone can help me....
