Why I'm getting StackOverflowException?

I’m getting StackOverflowException when I run below program. My doubt is how this program recursively calling each classes(ArrayTest1, ArrayTest2) fields without executing constructor method?

using System;

public class Program
{
    public static void Main()
    {
        Console.WriteLine("Hello World");
        var arraryTest = new ArrayTest1();
    }
}

public class ArrayTest1
{
    ArrayTest2 arrayTest2 = new ArrayTest2();
    public ArrayTest1()
    {
        Console.WriteLine($"{nameof(ArrayTest1)} Class Contructor Executed");
    }
}

public class ArrayTest2
{
    ArrayTest1 arrayTest1 = new ArrayTest1();
    public ArrayTest2()
    {
        Console.WriteLine($"{nameof(ArrayTest2)} Class Contructor Executed");
    }
}

>Solution :

Because you create an infinite chain of ArrayTest1 -> ArrayTest2 -> ArrayTest1 -> ArrayTest2 -> …

To understand why you are not getting any output, see C# constructor execution order

Important steps in your case (no inheritance involved):

• Member variables are initialized to default values
• Variable initializers are executed
• The constructor bodies are executed

You never reach constructor bodies, as the stack overflow happens in variable initializer
