C#: Preventing the console from closing at the end of the program

You've just created your first program in C#, you run it and... surprise. The console opens and closes without you having had time to see anything?

Don't worry, that's normal! Besides, this isn't a problem encountered only in C#, but in the majority of other languages as well.

The goal of a program is to run correctly, and to use as few resources as possible. So once everything is finished (with or without errors), it closes, regardless of the information it may have written to the console during its execution!

Solution

The solution is simple: you need to make the program wait for you to give it the order to stop! To do this, we'll use the following method:

Console.ReadLine();

The Console.ReadLine method is used to retrieve information entered by the user via the keyboard.

But here, we're not going to store this information: as soon as the user presses the "Enter" key, the program will stop and the console will disappear!

Here's a small example program:

static void Main(string[] args)
{
    Console.WriteLine("Je peux lire ceci");
    Console.WriteLine("et ceci.");

    // Le programme va attendre 
    // l'appui d'une touche pour se fermer
    Console.ReadLine();
}
