Operate with the combinations in vb.net

[tgab11]

Hi,
I don't know if this is the right place to address my issue.
I am using you package on VS in a vb.net application. I've tried to do what you did in here:

https://trycatch.me/combinatorics-in-net-part-i-permutations-combinations-variations/

When it comes to send the combination to a MsgBox, I get errors. I am trying this:

Dim np As New List(Of Integer)

        For i = 0 To 5

            np.Add(i)

        Next

        Dim q As New Combinations(Of Integer)(np, 3)

        For Each v As Integer In q

            MsgBox(String.Join(",", v))

        Next

To mimic what you did there, but it's not working.

I have also tried:

Dim str As String = String.Join(",", q)

MsgBox(str)

But the result is just a sequence of "System.Collections.Generic.List`1[System.Int32]". They are in the number of q.count.

The list of combinations I get is an IReadOnlyList(Of Integer), the program doesn't let me do anything except q.count, so far.

The final aim is to work with the elements of the combinations to mime nested loops, so I need to convert, somehow, the combinations into a matrix (number of combinations, number of elements in each combination), or similar. The MsgBox in the example is just to try and see what happens, but nothing happens unfortunately.

I am really sorry if this is a stupid question, I am not an expert.

Thanks for you time

For Each v As Integer In q

Try removing As Integer from the above statement. The type of v should be an IReadOnlyList(Of Integer) of 3 integers, which you can then process, though maybe not join them as a string, since they are not strings or characters.
