How can I compare a users input to a list of methods?

I'm writing some code where I have made a few methods and have put all of them in a list however I want the user to be able to choose a method from the list and then run that method as i dont want all the methods to run and only output the answer of chosen method as this is inefficient.

class program
    {
        //arrays
        static void Arrays()
        {
            Console.WriteLine("Enter number of cars:");
            Console.ReadKey();
        }

        // List
        static void List()
        {
            Console.WriteLine("Enter items for shopping list");
            shoppingList.Add("Apples");
            shoppingList.Add("oranges");
            shoppingList.Add("milk");
            shoppingList.Add("butter");

            Console.ReadKey();
        }

        static void Main(string[] strings)
        {
            List<Action> methods = new List<Action>();

            methods.Add(Arrays);
            methods.Add(List);

            Console.WriteLine("what method do you want:");
            string answer = Console.ReadLine();

            foreach (Action a in methods.Where(//one of the methods == answer));
                Console.WriteLine(//the method that is == answer);

            if (answer == //one methods in list)
            { 
                Console.WriteLine(////the method that is == answer);   
            }
        }

You could use a dictionary:

Dictionary<string, Action> methods = new(StringComparer.OrdinalIgnoreCase);
methods.Add(nameof(Arrays), Arrays);
methods.Add(nameof(List), List);

Console.WriteLine("what method do you want:");
string answer = Console.ReadLine();
if(methods.TryGetValue(answer, out Action doIt))
{
    doIt();
}
