Question

int x = 9; 
List<string> list = new List<string> {"a", "b"};

I want list to be: a b a b a … until list.Count = x. How might I achieve this?

Something like this should work. I did not check it, let it be an exercise for you 🙂

int currentCount = list.Count;

for (int i=0; i<x; ++i)
{
     list.Add(list[i%currentCount]);  
}
