In this tutorial, we will see both how to input information into our application and how to display it.
1 - Keyboard Input
To enter information via the keyboard, all we need to do is write the following line of code
Console.ReadLine();When we do this, if we press the play button in Visual Studio, it will allow us to enter any value until we press enter.
However, if we only receive the information, we’re not doing anything with it, so we need to store it in a variable
String etradaTeclado = Console.ReadLine();
2 - Output to Screen
Displaying information is very simple, we just need to use the statement Console.WriteLine(variable)
Therefore, we can make an example that asks the user for their name and displays it on the screen.
Console.WriteLine("Introudce tu nombre:");
string nombre = Console.ReadLine();
Console.WriteLine($"El nombre es {nombre}");
Console.ReadKey();
The code piece we see to display in Console.WriteLine() is called string interpolation which we will see further on in this course.
Finally, we put a Console.ReadKey() so that the code execution pauses until we enter a single character via the keyboard
