How does a static constructor work?

Question

namespace MyNameSpace
{
    static class MyClass
    {
        static MyClass()
        {
            //Authentication process.. User needs to enter password
                


        

Answer 1

It's ensured that a static class's constructor has been called before any of its methods get executed. Example:

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("Press enter");
        Console.ReadLine();
        Boop.SayHi();
        Boop.SayHi();
        Console.ReadLine();
    }

}

static class Boop
{
    static Boop()
    {
        Console.WriteLine("Hi incoming ...");
    }

    public static void SayHi()
    {
        Console.WriteLine("Hi there!");
    }
}

Output:

Press enter

// after pressing enter

Hi incoming ...

Hi there!

Hi there!
