public class Class1
    {
        string name;
        public Class1(string name)
        {
            this.name = name;
            Console.WriteLine("1.");
            Console.WriteLine("parent constracter:"+name);
        }
    }

public class Class2:Class1
    {
        string age;
        public Class2()
            : base("sucre")
        {
            Console.WriteLine("2.");
        }
    }

public class Class3:Class2
    {
        public Class3() : base()
        {
            Console.WriteLine("3");
        }

    }

class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("实例化1   ++++");
            Class1 a = new Class1("kk");
            Console.WriteLine("实例化2   ++++");
            Class2 b = new Class2();
            Console.WriteLine("实例化3   ++++");
            Class3 c = new Class3();
        }
    }

Console:
实例化1   ++++
1.
parent constracter:kk
实例化2   ++++
1.
parent constracter:sucre
2.
实例化3   ++++
1.

base: 调用父类构造方法.
parent constracter:sucre
2.
