Efficiency: Creating an array of doubles incrementally?

Question

Consider the following code:

List<double> l = new List<double>();

//add unknown number of values to the list
l.Add(0.1); //assume we don't have these values ahead of time.
l.Add(0.11);
l.Add(0.1);

l.ToArray(); //ultimately we want an array of doubles

Anything wrong with this approach? Is there a more appropriate way to build an array, without knowing the size, or elements ahead of time?

Answer 1

There's nothing wrong with your approach. You are using the correct data type for the purpose.
