Question

So this is what I have for my list.

[0], [1], [2], [3], [4]

I want to be able to loop through these – But the trick here is that I want to start at an offset then loop around back to that offset?

ex.

[0], [1], [2], [3], [4]
      o-->            
//Start at offset 1 then get 2, 3, 4 then loop back around to zero

ex2.

[0], [1], [2], [3], [4]
                o-->            
//Start at offset 3 then get 4, then loop back around to zero, then 1, 2 

I thought about using the regular List<T> and trying to implement this concept into a for loop but I’m not sure if I want to do that if theirs a more concise way of doing so.

Basically don’t start at 0 and loop back to the start and go through the elements back to the offset.

You are really describing a ring buffer or circular buffer.

The simple implementation is

int start; // Set your desired start offset

for (int i = start; i < myList.Length; i++)
{
    // do stuff
}

for (int j = 0; j < start; j++)
{
    // do stuff
}
