StackOverFlow exception while setting a property via the construction

Question

I have a simple class model with a single property inside.

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            UF uf = new UF(5);
        }
    }
}

namespace ConsoleApp1
{
    class UF
    {
        public UF(int N)
        {
            this.n = N;
            Console.WriteLine(this.n);
        }

        private int n
        {
            get => n;

            set
            {
                if (value <= 0) throw new ArgumentOutOfRangeException(nameof(value));
                else
                {
                    n = value;
                }
            }
        }

    }
}

Who can explain to me why after class initialization via my constructor I am having the StackOverflow exception on the setter property?

Answer 1

Your exception comes from here :

n = value;

You have declared your property with the name of n and constantly tries to rewrite its value. Try renaming your property to something like N and it should be fine.

class UF
{
    public UF(int N)
    {
        this._n = N;
        Console.WriteLine(this.n);
    }

    int _n;
    private int N
    {
        get => _n;

        set
        {
            if (value <= 0) throw new ArgumentOutOfRangeException(nameof(value));
            else
            {
                _n = value;
            }
        }
    }

}
