Static Constructor Vs Non-Static Constructor

• A Constructor that is defined using static keyword is a static constructor. Rest of the others are Non-Static only. 
• Static Constructor is the first block of code which executes under a class where as Non-Static Constructor gets executed only after creating the object of class as well as each and every time the object of class is created.
• In the life cycle of a class a Static Constructor gets called one and only one time whereas a Non-Static Constructor gets called either for zero(no objects are created) or n times (n objects are created).
• A Static Constructor can never be parametrized because it is the first block of code that executes in a class and more over it is implicitly called and Non-Static constructors can be parametrized because they are explicitly called and we have a chance of sending values to the parameters.

            StatCon s2 = new StatCon();
            StatCon s3 = new StatCon();
            Console.ReadLine();
        }
