using System;

namespace ConsoleApp1
{

    public class Panda
    {
        public Panda Mate;
        public void Marry(Panda partner)
        {
            Mate = partner;
            partner.Mate = this;
        }
    }


    class Program
        {

            static void Main(string[] args)
            {

                Panda female= new Panda { };
                Panda male= new Panda { };

                male.Marry(female);
              //  female.Marry(male);
                Console.WriteLine(male.Mate.ToString());
                Console.WriteLine(female.Mate.ToString());

                Console.ReadLine();
            }
        }
    }
}

此代码来自Albahari并添加了我的代码。如何将相关合作伙伴名称输出到字符串？我想根据阶级关系输出男性伴侣姓名和男性伴侣姓名。我需要返回类实例名称而不是返回其属性的名称。或者name属性应该自动命名为类实例。

I try 
            var name = nameof(female.Mate);
            Console.WriteLine(name);
            Console.ReadLine();
        } but this outputs "Mate"

Answer 1

public class Panda
{
    public string name;
    public Panda Mate;
    public void Marry(Panda partner)
    {
        Mate = partner;
        partner.Mate = this;
    }

    public override string ToString()
    {
        return this.name + " = " + Mate.name;
    }
}


class Program
{

    static void Main(string[] args)
    {

        Panda female = new Panda { };
        Panda male = new Panda { };

        female.name = "Lilly";
        male.name = "Shadow";

        male.Marry(female);
        //  female.Marry(male);
        Console.WriteLine(male.ToString());
        Console.WriteLine(female.ToString());

        Console.ReadLine();
    }
}

请尝试此代码

public class Panda
{
    public string name;
    public Panda Mate;
    public void Marry(Panda partner)
    {
        Mate = partner;
        partner.Mate = this;
    }

    public override string ToString()
    {
        return this.name + " = " + Mate.name;
    }
}


class Program
{

    static void Main(string[] args)
    {

        Panda female = new Panda { };
        Panda male = new Panda { };

        female.name = nameof(female);
        male.name = nameof(male);

        male.Marry(female);

        Console.WriteLine(male.ToString());
        Console.WriteLine(female.ToString());

        Console.ReadLine();
    }

}
