4.4.1. Definition. Reading from keyboard

We have seen how to read strings (Console.ReadLine) and how to display on screen (Console.Write) as well as how to assign a value (=). We can also compare its value, using ==, or create a string from others if we join them with the symbol of the sum (+):

Thus, an example to ask our names and greet us using all these possibilities could be:

using System;

public class Example42

{

  public static void Main()

  {

    string greeting = "Hello";

    string secondGreeting;

    string name, farewell;

       

    secondGreeting = "How are you?";

    Console.WriteLine("What is your name?");

    name = Console.ReadLine();   

   

    Console.WriteLine("{0} {1}", greeting, name);

    Console.WriteLine(secondGreeting);

   

    if (name == "Albert")

      Console.WriteLine("So you say you are Albert?");

    else

      Console.WriteLine("So you are not Albert?");

    

    farewell = "Bye " + name + "!";

    Console.WriteLine(farewell);

  }

}
