What is difference between instance constructor and Static constructor in C#.Net

Main Differences are :

•  A Constructor declare using Static modifier was known as  Static Constructor. Rest of all were Instance Constructor.
• Static Constructor are responsible for initialization of static variables and Instance Constructor for initialization of instance constructor.
• A static constructor is called only one's in the execution of a class. Where as instance constructor gets called each time we create the object of the class. if no object is created. It is not called at all.
• static constructor is the first block of which gets executed under the class.
• A static constructor can't be parameterized because explicit calling of the constructor is not done.

Sample Example:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace ConsoleApplication1

{

    class staticconstructor

    {

        static staticconstructor()

        {

            Console.WriteLine("static constructor");

        }

         staticconstructor()

        {

            Console.WriteLine("non-static constructor");

        }

        static void Main()

        {

            Console.WriteLine("main method");

            staticconstructor st = new staticconstructor();

            staticconstructor st1 = new staticconstructor();

            Console.ReadLine();

        }

    }

}
