Error in return type-Class

I am new to C# and am testing on return types using array and a class. But Somehow I am stuck while trying to return a class' object. In class notWhole, I tried to pass an array as an argument to the constructor but somehow compiler throws an error saying "field initializer can't initialize non static field member".

class Whole
{
    int[] Arr = new int[3];
    public Whole()
    {
    }
    public Whole(int[] arr)
    {
        Arr = arr;
    }

    public int[] Spit()
    {
        return Arr;
    }

}

class notWhole
{
    int[] arr = new int[] { 1, 2, 3 };
    Whole w1 = new Whole(arr); //ERROR: can't pass an array(arr) as an argument
    public Whole wow()
    {
        return w1;
    }
}

C# does not allow you to access in initializers section other fields or methods You could use a constructor for your purposes. Also, if you use a static then you could create some side effects since all of your Whole instances will have a reference to same static array and a change in one of you Whole instance will be "available" in all others.

class notWhole
{
    Whole w1;
    public notWhole()
    {
        int[] arr = new int[] { 1, 2, 3 };
        w1 = new Whole(arr); 
    }

    public Whole wow()
    {
        return w1;
    }
}

I think that error message is enough to identify the reason, ie.,

A field initializer cannot reference the non-static field, method, or property

So you can try like this:

Whole w1 = new Whole(new int[] { 1, 2, 3 });

or like this :

static int[] arr = new int[] { 1, 2, 3 };
Whole w1 = new Whole(arr);
