            string choice = Console.ReadLine();
 
            switch (choice)
            {
                case "1":
                    Console.WriteLine("Chocolate, chocolate, chocolate!");
                    break;
                case "2":

                    Console.WriteLine("Cake, cake, cake!");
                    break;
                default:
                    Console.WriteLine("Hmmm, I don't know what you're favorite is.");
                    break;
            }

The switch statement is used to add condition to a piece of code. Its syntax is:

switch(<expression>)

                case <expression result>:

                                //code to execute

                                break;

                case <expression result>:

                                //code to execute

                                Break;

                .

                .

                .

                default:

                                //code to execute if there are no matching case

                                break;

expression – could be anything that would result in a value that would get evaluated in each of the cases.
