C# Language Durée de vie de la classe statique


Exemple

Une classe static est initialisée paresseusement sur l'accès des membres et reste active pendant toute la durée du domaine d'application.

void Main()
{
    Console.WriteLine("Static classes are lazily initialized");
    Console.WriteLine("The static constructor is only invoked when the class is first accessed");
    Foo.SayHi();

    Console.WriteLine("Reflecting on a type won't trigger its static .ctor");
    var barType = typeof(Bar);

    Console.WriteLine("However, you can manually trigger it with System.Runtime.CompilerServices.RuntimeHelpers");
    RuntimeHelpers.RunClassConstructor(barType.TypeHandle);
}

// Define other methods and classes here
public static class Foo
{
    static Foo()
    {
        Console.WriteLine("static Foo.ctor");
    }
    public static void SayHi()
    {
        Console.WriteLine("Foo: Hi");
    }
}
public static class Bar
{
    static Bar()
    {
        Console.WriteLine("static Bar.ctor");
    }
}
