An unhandled exception of type 'System.StackOverflowException' occurred in FreeOnTheBar.exe

Question

A StackOverflowException is thrown in my program and I don't understand why.
Can someone please explain what is happening?

This screenshot shows where exactly the exception is being thrown: Exception

My code:

class Program
{
    static void Main(string[] args)
    {
        var t = new WhiteWine();
        t.Name = "Tom";
        t.year = 1414;

        string f = t.Prepare;      
    }
}

class WhiteWine : Wine
{
    public override string Prepare
    {
        get
        {
            return $"Well, {this.Name} is a cold wine, therefor it served cold. \n All you need to di is take it out from the refrigerator, pour it into a glass and serve.";
        }
    }

    public override string Name
    {
        get
        {
            return $"{this.Name} ({this.year})";
        }
    }
}

public class Wine : Drink
{
    public int year { get; set; }
}

public class Drink : Idrink
{
    public virtual string Name { get; set; }
        
    public virtual string Prepare { get; }
}

Answer 1

The WhiteWine.Name get accessor produces infinite recursion, because you use this.Name to calculate the value of this.Name.

public override string Name
{
    get
    {
        return $"{base.Name} ({this.year})";
    }
}

This should fix the issue.
