    class statiConstructor

    {

        private static int a;

        static statiConstructor()

        {

            a = 10;

            Console.WriteLine("Static Constructor with static member value=" + a);

        }

        {

            Console.WriteLine("Method Call ");

        }

    }

    class UnderstandingStaticConstructor

    {

        public static void Main()

        {

         // In particular, a static constructor is called once, automatically, when the class is used for the first time.

            statiConstructor k = new statiConstructor();

            statiConstructor.MethodCall();
            statiConstructor.MethodCall();

Output:
