I am trying to figure how how to find all the combinations given the following information:

I start with a JSON dataset:

```
var choices = { 1: {'Q': 100, 'R': 150, 'W' : 250, 'T', 30},
                2: {'Q': 90, 'R': 130, 'W' : 225, 'T', 28},
                3: {'Q': 80, 'R': 110, 'W' : 210, 'T', 25},
                4: {'Q': 70, 'R': 90, 'W' : 180, 'T', 22},
                5: {'Q': 60, 'R': 70, 'W' : 150, 'T', 18},
                6: {'Q': 50, 'R': 50, 'W' : 110, 'T', 15},
                7: {'Q': 40, 'R': 30, 'W' : 80, 'T', 11},
                8: {'Q': 30, 'R': 25, 'W' : 50, 'T', 8},
                9: {'Q': 20, 'R': 10, 'W' : 25, 'T', 5},
                10: {'Q': 10, 'R': 5, 'W' : 15, 'T', 3}
              };

```

What I'm trying to figure out is how I can take this dataset, and generate all possible combinations when selecting either the 'Q', 'R', 'W', or 'T' element for each row.

So I hope my end result will be something like this

```
var allChoices = { 0: {1: {'Q': 100},
                       2: {'R': 130},
                       3: {'W' : 210},
                       4: {'W' : 180},
                       5: {'T', 18},
                       6: {'R': 50,},
                       7: {'Q': 40,},
                       8: {'T', 8},
                       9: {'R': 10},
                      10: {'W' : 15},
                     },
                 1: {...},
                 ...
                 1048576: {...}

              };

```

I used JSON because I think it is the easiest to visualize but does anyone know how I could go about accomplishing this in c#?

Let me know if this not clear enough I'm having a hard time figuring out how exactly to ask this question.
