I want to add elements to an array - as the user inputs integers

Question

Simply put - I'm starting out in C# and I'm trying to make a game right now (text based) where the computer generates a number between 20-30. Then the user takes a number from 1-3 away, then the computer takes a number between 1-3 away and the last person to take a number away to make 0 loses.

My question is - I want to setup an array for user answers, but I cannot figure out how to add an element to the array based on how many rounds it takes the user to finish the game. E.g. They could put in 1 a bunch of times and take their time - adding a lot of elements to the array, or they could do a bunch of 3s and make the game quick.

{
class Program
{
    static void Main(string[] args)
    {
        Random rnd = new Random();
        int randomStart = 0;
        randomStart = rnd.Next(20, 30);

        Console.WriteLine("The starting number is {0}", randomStart);
        Console.ReadLine();



    }
}

}

I've tried experimenting with array placement and ideas but I left them out of the code that I've put here because it may be easier for you to guide me by just adding to it.

Thanks for the help.

You can't change the dimensions of an array dynamically in C#. If you need to add values at run time you to use a different list type.

You might consider a standard List (https://msdn.microsoft.com/en-us/library/6sh2ey19(v=vs.110).aspx) or an ArrayList (https://msdn.microsoft.com/en-us/library/system.collections.arraylist(v=vs.110).aspx).
