C# advanced permutation scenario

Question

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\': 1         


        

Answer 1

check this out: Combination Generator in Linq

Another solution without LINQ, assuming you will be doing this on only 4 things per row, the easiest thing is to just brute force it and do nested foreach loops.

foreach ( choice in allChoices )
{
    foreach ( choice in allChoices )
    {
        foreach ( choice in allChoices )
        {
            foreach ( choice in allChoices )
            {
                // combine and add to a collection
            }
        }
    }
}

edit: added objects to loop over in foreach loops
