C# program to demonstrate the static constructor

Here, we are going to demonstrate the static constructor in C#?
Submitted by Nidhi, on November 08, 2020

Here, we will create a class with the static and non-static constructor. The static constructor is called before the first object of the class gets created.

Program:

The source code to demonstrate the static constructor is given below. The given program is compiled and executed successfully on Microsoft Visual Studio.

//C# program to demonstrate the static constructor

using System;

public class StaticDemo
{
    static StaticDemo()
    {
        Console.WriteLine("Static constructor called");
    }

    public StaticDemo()
    {
        Console.WriteLine("Non-Static constructor called");
    }
}

class Test
{
    static void Main(string[] args)
    {
        Console.WriteLine("Main() method called");

        StaticDemo S1 = new StaticDemo();
        StaticDemo S2 = new StaticDemo();
    }
}

Output:

Main() method called
Static constructor called
Non-Static constructor called
Non-Static constructor called
Press any key to continue . . .

Explanation:

In the above program, we created two classes StaticDemo and Test. The StaicDemo class contains a static and non-static constructor. The static constructor is always called before the first object of the class gets created.

Now look to the Test class that contains the Main() method. The Main() method is the entry point for the program. Here, we printed a message "Main() method called" on the console screen. Then we created the two objects then a static construct gets called after then non-static constructor called for both objects.
