从父字段C#确定层次结构整数

public class BaseClass
{
    protected int hierarchyLevel;

    public BaseClass(int level)
    {
        hierarchyLevel = level;
    }
}

public class DerivedClass : BaseClass
{
    public DerivedClass(int level) : base(level)
    {
    }

    public void PrintHierarchyLevel()
    {
        Console.WriteLine("Hierarchy Level: " + hierarchyLevel);
    }
}

public class Program
{
    public static void Main(string[] args)
    {
        DerivedClass derivedObj = new DerivedClass(2);
        derivedObj.PrintHierarchyLevel();
    }
}
